August 16, 2024/0 Comments/in App Design, app development, Appreneur, Blog, Business, Contractor Company Apps, custom mobile app for businesses, IOS Mobile App Development, Mobile Application Development, UI design, User Interface/by NS804 Content

What can a native app development agency offer you over a freelancer or a studio that uses hybrid or cross-platform development tools? In short, a native app developer will build your app, ensuring that it closely aligns with the guidelines and hardware specifications of the target platform. The result is an app that offers optimal performance and utilizes the unique features of each platform. Furthermore, the app’s look and feel are native to each platform, i.e., iOS and Android.

That’s not necessarily the result you will get if you hire a freelancer or studio that relies on cross-platform tooling. With freelancers, it’s hard to find developers equally proficient in iOS and Android native app development. Usually, a freelancer will have spent time mastering one of these platforms and only have some familiarity with the other. Nevertheless, it has become more common for freelance developers to use hybrid or cross-platform tools to target both platforms.

But what’s the deal with studios that use cross-platform tools when native app development is better? These studios are either understaffed or don’t have experienced staff on the team to handle native app development. And some more unscrupulous studios are simply trying to cut corners by offering an inferior service to their clients. However, there are cases where some of the more proficient studios know how to work around the pitfalls of cross-platform app development.

At NS804, we don’t have this problem, as we’ve built our reputation and achieved numerous accolades for creating top-quality native mobile apps. As of 2012, we’ve developed over 100 apps in several popular categories like business, entertainment, and productivity. That’s why we’ll reveal several key benefits you’ll enjoy when partnering with a native app development agency.

1. Build Apps That Always Perform At Their Best

We always use the best-in-class programming languages and tools. For iOS development, we use Xcode with the Swift language, and for Android, we use Android Studio with the Kotlin language. In cases with specific project requirements or legacy code, we’ll use Objective-C for iOS apps and Java for Android apps.

Also, we follow the best practices and guidelines set by Apple and Google and ensure that we stay current with our tooling and development methodologies. And that’s important because Apple and Google regularly update their programming languages, integrated development environments (IDEs), and software development kits (SDKs).

By regularly upgrading all of these, we can take advantage of the latest functionality, performance enhancements, and security features of iOS and Android. All this allows us to build apps for our clients that perform at their best upon release. Great-performing apps always satisfy users, leading to positive reviews and ratings on the app stores.

As you’re probably aware by now, a high number of reviews and ratings helps convince potential users to download your app. So, if you’re serious about the overall monetary performance of your app, partnering with a trusted native app development agency is your best bet!

2. Prioritize App Quality And Stability

While your users will be happy with an app that runs great after its first installation — this isn’t enough. Your app must run well consistently in the days, weeks, and months ahead. Nowadays, users are no longer willing to put up with buggy apps that crash on a whim. Mainly because platform holders, mobile device manufacturers, and developers have all upped their game.

But it’s not only a higher bar on quality that you need to be concerned about. Users are far less forgiving than you’d expect regarding app crashes, freezes, or sluggish start-up times. And don’t expect users to go easy on your app because their device warns them about excess memory use, and they decide to close other applications or clear the cache. In such cases, users will delete your app and look for a better alternative.

Consider the following metrics regarding app performance when planning your next project. Recent statistics reveal that users enjoy 99.81% crash-free sessions on Android and 99.93% on iOS. That’s a high percentage for both mobile platforms, so you must work closely with an app development agency to achieve similar or better results for your project.

Furthermore, users receive high memory usage rate warnings at 12.94% on Android and relatively lower at 5.49% on iOS. An agency experienced in developing native Android apps knows how to optimize their code for the Java Virtual Machine (JVM). While the JVM is great for making code portable across a wide range of devices, it’s far heavier on system resources because it must interpret and execute bytecode, unlike machine code that runs on bare metal.

3. Design A User Interface (UI) That Looks And Feels Native

The performance and stability of your app will win over many users. However, the look and feel of your app must be polished if it’s going to retain those users and cause them to recommend it to others. We already know that users are incredibly savvy and have high expectations of what a great app must look and feel like.

Therefore, you can’t rely on design trends that were hot two or three years ago to impress users. Also, don’t implement trailblazing graphic design techniques from the web, print media, or art world into your app. That’s because your app may end up with a design identity that looks too busy, pretentious, or artsy. Worse still, all this may hurt its usability, which is a huge turn-off for most users.

The best and most profitable mobile apps often boast clean and minimal UI design. Take a close look at several of the highest-grossing apps, such as Flipboard, Spotify, and WhatsApp, to see this design paradigm in action. To ensure you design a great UI that looks and feels native on iOS and Android, hire an app development agency to help you with this process.

While UI design may seem easy, it’s a fine art on its own, and that’s why the best studios hire talented UI designers to handle this all-important task. After the initial planning phase of your app, the UI designer will create flat wireframes for you to review. There will likely be some back-and-forth until you settle for the final UI design. For the best native UI results, it’s best to use Apple’s UIKit and SwiftUI frameworks for the iOS version and Jetpack Compose UI for the Android version.

4. Conduct Rigorous App Testing

No matter how good the early builds of your app seem, never ship it without a rigorous testing app process. Unfortunately, this is a challenging and complex process that requires an experienced hand. That’s why it’s a good idea to team up with an app development agency to help with the following types of testing methods:

Performance testing: It’s a method specifically for testing loading times, responsiveness, and system resource usage. If your app fails any part of this testing process, it’s too unstable to be released and requires further work.

Compatibility testing: Your app may work fine on the Android Emulator or the iOS Simulator, but you must still test on real hardware. Also, you must test to see how compatible your app is on the broadest range of devices possible. The testing process is more elaborate on Android than iOS due to the massive range of Android devices available.

Functionality testing: Ensure that all the functionality you planned for your app works properly. Furthermore, you’ll be able to determine whether or not any navigation issues impact the user journey negatively.

Security testing: One of the most crucial testing processes to evaluate the effectiveness of your app’s security. Even the slightest failure of this test means that your app is vulnerable to data breaches by bad actors like hackers, cyber terrorists, and authoritarian regimes.

Release testing: The final testing phase before it reaches your target audience. A common way to do this is by releasing a beta version to test among the development team and a small group of users who have signed up for the beta.

5. App Maintenance And Updates

After you release your app in the app stores, you must maintain it by regularly rolling out new updates and features. Even if you amaze early adopters with the first version of your app, they’ll soon lose interest if they see that you’re not updating your app at a regular cadence.

Moreover, you must regularly gather user feedback and conduct surveys to learn what new features users want and if they’re experiencing any issues with your app. It also makes sense to do this when you’re about to scale your app or introduce an important feature.

You could handle all this, but if you hire an agency to do it instead, your updates will be more robust and released on schedule. You’ll also have free time to plan your next app or focus on other aspects of your app business.

In Conclusion

Hiring a trusted native app development agency is a smart choice if you want the best for your users and app business. After all, the app development process is very challenging, with many pitfalls that you want to avoid, so you must find the right partner. Contact NS804 today to learn how we’ll help you create phenomenal native apps to stay ahead of the curve!

How to Develop a Native Android App: A Step-by-Step Guide

August 15, 2024/0 Comments/in app development/by Juice AI

Developing a native Android app involves creating software specifically designed to run on Android devices, using the Android operating system’s native tools and capabilities.

This specificity allows developers to utilize hardware and software features like camera, GPS, and notifications more effectively, resulting in a smoother and more efficient user experience.

For businesses and developers alike, understanding the intricacies of how to develop native Android apps is crucial. With the Android market share continuing to grow, having a well-designed and functional app can set you apart from the competition. By focusing on native development, you ensure that your app is optimized for performance, security, and user engagement.

Ready to take the next step in your app development journey? Get a free quote from NS804, experts in native mobile app development, and bring your vision to life.

Setting Up Your Development Environment

The first step in learning how to develop a native Android app is setting up your development environment. This process involves installing the necessary tools and software that will enable you to build and test your app effectively.

Begin by downloading and installing Android Studio, the official integrated development environment (IDE) for Android development. Android Studio provides a comprehensive suite of tools, including a code editor, a visual layout editor, and an Android emulator, which allows you to test your app on different virtual devices.

Once Android Studio is installed, you will need to install the Java Development Kit (JDK). Java is the primary programming language used for Android development, so having the latest version of the JDK is essential. You can configure Android Studio to use the JDK by navigating to the project structure settings within the IDE.

Next, set up the Android SDK (Software Development Kit). The SDK includes various tools, libraries, and APIs necessary for building and testing Android apps. Android Studio typically manages the SDK setup for you, but you can customize the SDK components based on your project’s requirements.

Finally, configure an Android Virtual Device (AVD) within Android Studio. An AVD simulates an Android device on your computer, allowing you to test your app’s functionality and performance without needing a physical device. You can create multiple AVDs to test your app on different screen sizes and Android versions.

With your development environment set up, you’re ready to dive into coding and start building your native Android app. Properly setting up your tools ensures a smoother development process and helps you avoid common pitfalls and issues down the line.

Understanding Android App Architecture

To master how to develop a native Android app, it’s crucial to understand the underlying architecture. Android app architecture is a structural design that guides the development process, ensuring that your app is scalable, maintainable, and testable.

At the core of Android app architecture is the Model-View-ViewModel (MVVM) pattern. This pattern helps to separate the app’s data (Model) from its UI (View), with the ViewModel acting as an intermediary. The Model holds the business logic and data, the View displays the data and interacts with the user, and the ViewModel handles the communication between the Model and the View.

Another key component is Activities and Fragments. An Activity is a single, focused task that the user can perform, such as a login screen or a settings page. Fragments are modular sections of an Activity, allowing for more flexible and reusable UI components. Together, they form the building blocks of your app’s user interface.

Understanding Intents and Services is also essential. Intents are messaging objects used to request actions from other app components or even other apps. Services, on the other hand, perform long-running operations in the background, such as downloading files or playing music. They ensure that your app remains responsive and efficient.

Finally, you need to be aware of Android Jetpack, a suite of libraries, tools, and guidance provided by Google to help you build robust Android apps. Jetpack components such as LiveData, Room, and Navigation are designed to work together seamlessly, reducing boilerplate code and simplifying complex tasks.

By grasping these architectural principles, you’ll be better equipped to create high-quality, efficient, and maintainable Android apps. A solid understanding of Android app architecture lays the foundation for successful app development, enabling you to tackle more advanced topics with confidence.

Writing Your First Android App Code

Once you have a firm grasp of how to develop a native Android app and understand its architecture, it’s time to dive into writing your first lines of code. This step is crucial as it sets the groundwork for your entire application.

Begin by setting up your development environment using Android Studio, the official Integrated Development Environment (IDE) for Android development. Android Studio provides a comprehensive suite of tools to streamline your coding experience. After installation, you’ll need to create a new project. Choose a project template that suits your needs, such as an empty activity or a basic activity with a layout file.

Next, you’ll encounter the MainActivity.java (or MainActivity.kt for Kotlin) file. This file serves as the entry point for your application. It extends the AppCompatActivity class and overrides the onCreate() method. Within this method, you will set up your user interface by linking the activity to its XML layout file using setContentView(R.layout.activity_main).

To create a basic user interface, navigate to the res/layout/activity_main.xml file. This XML file defines the layout of your activity. You can use various UI components like TextView, Button, and EditText by adding their XML tags within a layout container such as LinearLayout or ConstraintLayout. For instance:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical">

    <TextView 
        android:id="@+id/textView" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:text="Hello, World!" />

    <Button 
        android:id="@+id/button" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:text="Click Me" />

</LinearLayout>

With the UI components defined, you can now handle user interactions in the MainActivity file. For example, to respond to a button click, you can set an OnClickListener within the onCreate() method:

Button button = findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        TextView textView = findViewById(R.id.textView);
        textView.setText("Button Clicked!");
    }
});

Writing your first Android app code may seem daunting at first, but with practice, it becomes second nature. The key is to start simple, gradually incorporating more complex features as you grow more confident in your coding abilities.

Testing and Debugging Your Android App

After writing your first lines of code, the next critical step in how to develop a native Android app is to rigorously test and debug your application. Ensuring that your app runs smoothly and is free of bugs is essential for a positive user experience.

Begin by using the built-in testing tools provided by Android Studio. One of the most powerful tools at your disposal is the Android Emulator. This emulator allows you to simulate a wide range of devices and Android versions, enabling you to test your app’s performance across different environments. Start by setting up virtual devices that mimic the hardware and software specifications of your target audience.

Unit testing is an integral part of the development process. In Android development, you can use frameworks like JUnit to write and run unit tests. These tests help verify that individual components of your app work as expected. For example, you can create a unit test for a function that calculates the sum of two numbers:

public class CalculatorTest {
    @Test
    public void addition_isCorrect() {
        assertEquals(4, Calculator.add(2, 2));
    }
}

For UI testing, consider using Espresso, a framework that allows you to write automated tests for your app’s user interface. Espresso tests interact with UI components and verify their behavior. Here’s an example of an Espresso test that checks if a button click updates a TextView:

@Test
public void buttonClick_updatesTextView() {
    onView(withId(R.id.button)).perform(click());
    onView(withId(R.id.textView)).check(matches(withText("Button Clicked!")));
}

Debugging is another crucial aspect of app development. Android Studio offers a comprehensive debugger that allows you to set breakpoints, inspect variables, and step through your code line by line. This helps identify and resolve issues more efficiently. Additionally, the Logcat tool provides real-time logging of your app’s behavior, helping you track down and fix runtime errors.

Remember to also test your app on physical devices. Emulators are great for initial testing, but they can’t replicate the exact performance characteristics of real hardware. Testing on actual devices ensures that your app performs well in real-world scenarios.

By incorporating thorough testing and debugging practices, you can significantly improve the quality and reliability of your native Android app, paving the way for a successful launch.

Deploying and Updating Your Android App

After thorough testing and debugging, the next step in how to develop a native Android app is deploying and updating your application. Deployment is the process of making your app available to users, typically through the Google Play Store.

To start, you’ll need to create a developer account on the Google Play Console. This platform provides all the tools necessary for publishing and managing your app. Once your account is set up, you can begin by preparing your app for release. This involves generating a signed APK or Android App Bundle, which is a package file format used for distributing and installing apps.

Follow these steps to generate a signed APK in Android Studio:

In Android Studio, go to Build > Generate Signed Bundle / APK.
Select either Android App Bundle or APK and click Next.
Choose an existing key or create a new one to sign your app.
Follow the prompts to complete the process and generate the signed APK or App Bundle.

Once you have your signed APK or App Bundle, you can upload it to the Google Play Console. Here, you’ll also need to provide important details about your app, such as its title, description, screenshots, and promotional graphics. Additionally, it’s crucial to set the appropriate app permissions and adhere to Google’s policies to ensure a smooth review process.

After submitting your app, Google will review it to ensure it meets their guidelines. Once approved, your app will be available for download on the Google Play Store. But the process doesn’t end there. Regular updates are vital to maintain user engagement and satisfaction.

To update your app, you’ll need to follow a similar process: generate a new signed APK or App Bundle with the latest changes, and then upload it to the Google Play Console. Make sure to provide clear release notes that inform users about the new features, improvements, or bug fixes included in the update.

Effective deployment and consistent updates are key to the success of your native Android app. By ensuring a smooth launch and keeping your app up-to-date, you can build a loyal user base and achieve long-term success.

Crucial Threads in Mobile App Development You Should Know

August 11, 2024/0 Comments/in 2024 mobile app trends, app development, app launch/by

In the ever-evolving landscape of mobile app development, understanding threads is pivotal. Threads are essentially the smallest unit of processing that can be performed in an operating system. In the context of mobile applications, threads enable multitasking, allowing your app to perform multiple operations simultaneously without compromising user experience.

Imagine an app that needs to download data from the internet, update the user interface, and handle user inputs all at the same time. Without efficient threading, these tasks would clog the main thread, leading to sluggish performance and frustrated users. By delegating tasks to different threads, developers can ensure that their apps run smoothly, efficiently, and responsively.

For example, in an e-commerce app, while the main thread handles user interactions, a background thread can manage data fetching from the server. This ensures that the user can continue browsing products without experiencing any lag.

However, threading is a double-edged sword. While it can significantly enhance performance, it also introduces complexity. Developers must be cautious about thread synchronization, deadlocks, and race conditions, which can lead to unpredictable behavior if not properly managed.

If you’re looking to build a mobile app that leverages the power of threading for optimal performance, get a free quote from our experts at NS804 today. Stay tuned as we delve deeper into threading models, common challenges, and best practices in the subsequent sections.

Understanding Threading Models

Threading models are crucial frameworks that dictate how threads are managed and executed within an application. In mobile app development, understanding these models helps developers design applications that are both efficient and responsive. Broadly, threading models can be categorized into single-threaded and multi-threaded models.

In a single-threaded model, the application runs all tasks on a single thread, typically the main thread. This model is simpler to implement but comes with significant limitations. Since all tasks share the same thread, any long-running operation can block the main thread, leading to a freezing or unresponsive user interface. This is why single-threaded models are generally not suitable for complex or resource-intensive applications.

On the other hand, a multi-threaded model allows multiple threads to run concurrently, distributing tasks across different threads. This approach can greatly enhance performance and responsiveness. For instance, in a social media app, one thread can handle user interactions while another fetches posts from the server, and yet another processes images. This parallelism ensures that the user experience remains fluid and smooth.

Moreover, there are specialized threading models like the thread pool model, which pre-allocates a number of threads and reuses them for various tasks. This is particularly useful in scenarios where the overhead of creating and destroying threads could degrade performance.

Understanding these threading models is essential for making informed decisions in mobile app development. Choosing the right model not only improves performance but also enhances the overall user experience, making your app more robust and scalable.

Common Challenges with Threads

While threading can significantly improve the performance and responsiveness of a mobile app, it also introduces a set of complex challenges that developers must navigate. One of the most daunting issues is thread synchronization. When multiple threads access shared resources, there is a risk of data corruption or inconsistency. Proper synchronization mechanisms like locks, semaphores, and monitors are essential but can lead to deadlocks if not managed correctly.

Another common challenge is thread leakage, which occurs when threads that are no longer needed are not properly terminated. This can consume valuable system resources, leading to performance degradation over time. Developers must ensure that threads are appropriately managed and terminated when they have completed their tasks.

Race conditions present another significant hurdle. These occur when the outcome of a process depends on the sequence or timing of uncontrollable events, such as thread execution order. Race conditions can lead to unpredictable behavior and are notoriously difficult to debug. To mitigate this, developers often employ techniques like atomic operations and thread-safe data structures.

Error handling in a multi-threaded environment is also more complicated. Exceptions thrown in one thread may not propagate to the main thread, making it challenging to diagnose and fix issues. Proper logging and monitoring are crucial for identifying and resolving such problems.

Lastly, balancing thread overhead is vital. While multi-threading can improve performance, it can also introduce overhead from context switching, synchronization, and resource management. Developers must strike a balance to ensure that the benefits of multi-threading outweigh its costs.

By understanding and addressing these common challenges, developers can harness the power of threads to build efficient, responsive, and robust mobile applications.

Best Practices for Thread Management

Effective thread management is crucial for optimizing the performance and reliability of mobile applications. Adhering to best practices can help developers avoid common pitfalls and make the most of multi-threading capabilities. One fundamental practice is to minimize the number of threads. While it might be tempting to create multiple threads for various tasks, excessive threading can lead to overhead, diminishing the performance gains. Utilizing thread pools can help manage the number of active threads and maximize resource utilization.

Another best practice is to ensure proper synchronization. Developers should use synchronization mechanisms like mutexes, locks, and semaphores to manage access to shared resources. This prevents data corruption and inconsistencies but must be implemented carefully to avoid deadlocks. Utilizing high-level concurrency utilities provided by modern programming languages can simplify this process.

It’s also essential to implement graceful thread termination. Threads should be designed to complete their tasks and terminate cleanly. This involves handling interruptions appropriately and ensuring that resources are released properly. Failing to manage thread lifecycles can lead to resource leaks and degraded performance over time.

Employing thread-safe data structures is another critical aspect of thread management. Using built-in thread-safe collections and atomic operations can help avoid race conditions and ensure data integrity. Developers should be cautious about using non-thread-safe structures in a multi-threaded environment.

Monitoring and logging are indispensable for effective thread management. Implementing comprehensive logging can help track thread activities, identify bottlenecks, and diagnose issues. Monitoring tools can provide insights into thread performance and resource usage, enabling proactive management and optimization.

Lastly, understanding the specific threading model and limitations of the platform you’re developing for is vital. Different mobile platforms may have varied threading architectures and constraints. Tailoring your threading strategy to align with platform-specific guidelines ensures optimal performance and stability.

By following these best practices, developers can effectively manage threads, resulting in more responsive, stable, and efficient mobile applications.

Tools for Optimizing Thread Performance

Leveraging the right tools is essential for optimizing thread performance in mobile app development. These tools help developers analyze, manage, and enhance the efficiency of multi-threaded applications.

One invaluable tool is profilers. Profilers such as Android Studio Profiler and Xcode Instruments provide insights into thread activity, CPU usage, and memory consumption. They help identify performance bottlenecks and thread contention issues, enabling developers to make informed optimizations.

Thread analyzers are another category of tools that assist in thread management. Tools like Traceview for Android and Time Profiler for iOS allow developers to visualize thread execution and interactions. These tools can reveal inefficiencies and highlight areas where threading strategies can be improved.

Using concurrent collections and utilities provided by modern programming languages can also streamline thread management. Java’s java.util.concurrent package and Swift’s Grand Central Dispatch (GCD) offer thread-safe collections and high-level concurrency utilities. These abstractions simplify the implementation of multi-threading and ensure better performance.

Memory leak detectors are critical for maintaining efficient thread performance. Tools such as LeakCanary for Android and Instruments’ Leaks tool for iOS help identify memory leaks that can degrade performance over time. By detecting and resolving leaks, developers can ensure that their applications remain responsive and performant.

Automated testing frameworks like Espresso for Android and XCTest for iOS can be used to test the behavior of multi-threaded applications under various conditions. These frameworks enable developers to simulate different scenarios and validate that their thread management strategies hold up under stress.

Lastly, continuous integration (CI) tools such as Jenkins and CircleCI can be configured to run performance tests as part of the development pipeline. By integrating thread performance testing into CI workflows, developers can catch regressions early and maintain high performance throughout the development lifecycle.

By incorporating these tools into their development process, mobile app developers can optimize thread performance, leading to more efficient and responsive applications.

Case Studies of Effective Thread Usage

Examining real-world case studies of effective thread usage provides valuable insights into best practices and strategies for mobile app development. These examples highlight how various companies and developers have successfully leveraged threading to enhance app performance and user experience.

iOS Developer in Richmond: What Factors Should You Consider When Picking A Developer?

July 10, 2024/0 Comments/in app developers Richmond, Blog, IOS Mobile App Development, Mobile Application Development/by NS804 Content

Finding an iOS developer in Richmond can be tricky when you do not know how to separate the good from the best. While most developers may claim to have the basic skills to weave together a functional app, there are more nuances that enable the best developers to fork out world-class iOS app implementations. At NS804, we have a long documented history of completing elite projects for clients in Richmond.

In this piece, we highlight qualities that make Richmond’s best iOS app developers stand out. If you are seeking a development partner for your next iOS app, this checklist should help you make an objective decision. We will also discuss why working with a Richmond-based app developer may be better than an offshore developer.

Mastery of the iOS Software Development Kit

The iOS Software Development Kit provides a set of protocols, classes, data types, and an overall framework for iOS app development. A firm understanding of the framework is necessary for the proper implementation of various app functionalities such as sourcing and filtering, resource management, text management, and date and time calculations.

Apple provides the SDK for free, which enables developers to build and test apps with ease. The best developers keep up with updates to the SDK as well as how best to leverage such changes to improve the products they are building. The best way to evaluate a developer’s proficiency would be to consider products they have built in the past. They should have evidence of building feature-rich, secure, and smoothly functioning apps.

Proficiency in Xcode

Apple’s integrated development environment, Xcode, allows for faster app building in MacOS. The IDE allows developers to interactively preview the features they are building while also offering enhanced code completion. Xcode is free and it’s user interface is user-friendly unlike other IDEs that can look complicated and intimidating. Nonetheless, it has a rich set of tools for simulating all Apple devices, easy version control, and extensions for customizing the development process.

Xcode is the only official IDE for building Apple Developers and any expert iOS app developer ought to be well-conversant with it.

Adaptability

iOS developers must possess the ability to respond to evolutions in the industry. Each year, there are new tools and frameworks meant to enrich app features or ease the development process. The best development companies have a firm dedication to embracing such changes. When picking an iOS app developer in Richmond, you ought to inquire about their stance on app development technologies. Inquire whether they have adopted emerging best practices in the iOS app space. There are developers who have managed to carve out space for themselves as thought-leaders on emerging technologies. At NS804, we are certainly part of the conversation and are keen on keeping up to speed with the evolution.

Adaptability extends to being able to customize projects to specific client demands. During the project scoping phase, it is important to lay out every deliverable and explain how exactly to build it.

Team Collaboration

Building an iOS business app often requires a collaborative effort. It is highly unlikely that a single developer is able to deliver the app on when there is a tight time constraint. A team of developers allows a development project to be broken down into parallel deliverables with preset milestones. A team setting also allows for specialization within the team whereby one or more developers works on the UI while others build and test the backend functionalities.

Working with a team also helps in ensuring project continuity whereby even when one person leaves the team, an equally capable replacement can be sought. A team setting is also more likely to lead to greater creativity and problem solving ability. The team can compare and choose between several approaches to a design problem, leading to richer output.

Project Management Skills

One of the biggest challenges in iOS app development projects is failure to adhere to agreed-upon project specifications. During an initial meeting with a potential app development partner, it is important to get a sense of their project management approach. Are they keen on fine project details and dates? Do they have a framework for reporting project progress? What tools do they use to report to clients? How do they handle projects that have extended beyond set deadlines?

These questions are important because improper management can result in project cost overruns. Running out of funds can cripple and otherwise well-built project. As such, it is important to map out exactly how the project will be managed and where necessary outsource the management to a third party.

Performance Optimization

The best app developers must adhere to best practices for performance optimization. A well-optimized app runs smoothly across all devices a user may be using. It is important to keep the code base clean by avoiding unnecessary lines of code. All images used in the app should be compressed and in the right formats for faster page loads. Good development practices insist on efficient memory management to minimize leaks.

When it comes to UI implementation, there are certain animations that could slow down the app. The team ought to pick light transitions and animations that add value to the user experience.

Part of optimization involves reducing an app’s drain on the device battery. By using lower accuracy modes on location tracking, it is possible to reduce battery drain without sacrificing app performance. Minimizing an app’s background processing when not necessary is another way to reduce battery drain.

Proper Security Architecture Design

A great development team must understand how to best incorporate Apple’s security features into the apps they are building. They must understand the security threats that an app is likely to face based on the features it has and expected user behavior. For instance, certain apps should not allow screen recording because sensitive details such as banking app login could be compromised.

All code should be assessed for vulnerabilities such as hard-coded sensitive information that hackers can exploit. The libraries and frameworks used in building the app should also be trustworthy. They should have a big enough community of users and proper documentation to inspire confidence.

All data transfers between the app and the server must be through a secure protocol to prevent man-in-the-middle attacks. Adding two-factor authentication for the most sensitive apps adds another layer of security to the app.

Developer must make use of Apple’s security features such as FaceID for secure access to their apps. Regular security updates are important for fixing vulnerabilities that may be realized in the app’s lifetime.

When choosing an iOS development team, you must consider all this. Due diligence is paramount to establish whether proposed app security measures can are sufficient given the nature of your proposed app.

Quality Assurance Testing

The right iOS development team must be able to write and carry out tests for app functionalities as well as robustness and security. There is a wide range of frameworks for app testing, including XCTest and Test Navigator. The goal is to always write reliable and maintainable code without bugs.

While planning the app development process, there has to be a conversation about sufficient testing. The team should have a clear methodology of testing their code.

Flaws that end up in the production phase pose a significant threat to a brand. A bug can quickly tarnish a brand’s reputation for excellence especially when it takes too long to be flagged and fixed. Sufficient security testing also serves to protect a business from potential liability in case of a data breach.

App testing is also important because Apple has very strict guidelines for approving apps for the App Store.

World-Class Design Principles

Your app development partner should have a firm understanding of UI/UX design principles that enable creation of visually appealing and easy-to-use iOS applications. With a myriad of tools available for the design phase, the development team should have a formidable front-end development team.

Apple does provide Human Interface Guidelines (HIG) which, if followed, allow for the creation of intuitive and user-friendly apps. One such guideline states that the app’s elements should defer to the content being displayed. As such, the app itself should not distract users from the primary purpose of using the app.

The HIGs also propose a model for choosing controls to integrate into an app’s UI. A switch is best used to pick between two options while a slider is better implemented for a range. A Bluetooth on or off toggle is an example of a switch. Adjusting screen brightness on the UI happens through a range slider.

Customer Focus

Before settling on a developer to work on your iOS app, you need to consider their overall customer focus rating. How well do they meet their customers’ expectations? While this may sound like a broad question, there are specific indicators of commitment to user satisfaction.

First, there has to be a commitment to understand the business objectives that the app is meant to help fulfill. Whether it is a HR management app or an e-commerce channel, the app is linked to the bottom line. The development team has to link the building process with end goals such as improving productivity, customer engagement, information access, or any other specific goal.

Other indicators of this commitment are clear and effective communication channels. Every organization has its own culture, even when the stakeholders therein are not aware. There needs to be transparency with customers about project progress and challenges.

Proactiveness

The best iOS developers can anticipate challenges in the development cycle and take proactive action. This often comes from past project experience, but it is also made possible by keeping open communication lines amongst team members and with the client. Your initial meetings with a potential developer may reveal how well they are able to adjust when unexpected problems emerge during a project.

Choosing a Developer in Richmond

Businesses in Richmond may benefit from working with an iOS developer team that has worked with local businesses. First, by working with a local developer, you may have an easier time managing the project compared to having a developer from a different time zone. Where there are urgent issues to address, a developer in Richmond may be easier to access and perhaps even set up face-to-face meetings with.

It is also important to consider the legal and regulatory compliance standards that your app must meet. Failure to adhere to data protection laws for instance could result in reputational, legal, and financial jeopardy. As such, your app’s architecture must be set up in a compliant manner. A developer in Richmond is more likely to understand the local regulatory landscape.

You may also find it easier to verify the reported customer experiences of a developer based in Richmond. You could perhaps reach out to clients listed on their portfolio for answers to questions you may have about the technical or customer service credentials of a developer before working with them.

iOS App Security Best Practices (2024 Guide)

June 4, 2024/0 Comments/in 2024 mobile app trends, App Design, business app, custom mobile app for businesses, future-proofing mobile apps, iOS app security, Medical Apps, mobile app security/by NS804 Content

In the ever-changing digital landscape, iOS app security has never been more crucial. With the increasing reliance on mobile applications for many things ranging from healthcare to financial transactions, the potential risks associated with potential breaches continue to grow exponentially. In 2024 especially, app security is growing by depth and sophistication. Attackers used the latest technologies and exploited vulnerabilities. The consequences of security breaches can be catastrophic. They can range from financial losses and reputational damage to user trust and legal repercussions.

iOS App Best Security Practices

Overview of IOS Security Features: Introduction to Built-in IOS Security Features

Apple’s iOS operating system is renowned for its strong and impenetrable security infrastructure. The operating system is specifically designed to protect users against outside and inside vulnerabilities. This section of the article describes some of the built-in security features that make iOS a preferred platform for safe and secure mobile applications:

Sandboxing: Apple uses sandboxing, a unique capability that allows each app to operate separately and in isolation from other apps. In case one app is affected, it prevents malicious apps from accessing other apps or affecting them.
Data protection API: iOS uses encrypted data to ensure that any consumer or user data is inaccessible without the user’s password or authentication.
App Transport Security (ATS): This feature enforces secure connections between the app and its servers using HTTPs which in turn prevents and protects data in transit from tampering or interception.
Keychain Services: Provides a secure way to store sensitive information such as passwords and cryptographic keys, ensuring that only authorized apps have access to this sensitive data.
Face ID and Touch ID: Biometric authentication mechanisms offer a secure and safe way for user authentication and authorization within the app.
Secure Enclave: iOS uses a secure enclave which is essentially a dedicated coprocessor designed to handle cryptographic operations, thus ensuring the security and confidentiality of sensitive information.

These steps help provide better app security, leading to the reliability of apps without the worry of unauthorized access of breach of confidential information, including personally-identifying information.

Secure Coding Practices

Input validation and sanitization: preventing injection attacks

Input validation and sanitization are crucial defenses against injection attacks, such as cross-site scripting (XSS) and injection attacks. Ensuring that all user inputs are properly validated and sanitized is crucial in preventing malicious data from being processed by iOS apps. Input validation and sanitization may involve checking input lengths, formats, time, and ranges and escaping or completely removing potentially harmful characters.

Avoid hard-coded secrets: using secure volts and environment variables

Using hard-coded secrets like passwords, API keys, and cryptographic keys into the app’s source code is a risky move. It can lead to a breach if the code is exposed to an unauthorized third-party. Instead, it’s advisable for developers to use environment variables or secure vaults to store such sensitive information. Tools like AWS secret manager, Apple’s keychain services, and Azure Key Vault provide secure storage solutions. These solutions keep secrets outside the codebase and make them only accessible to authorized parties.

Secure API usage: Using https and handling API keys securely

Securing API usage is crucial for protecting data in transit and at rest and ensuring the integrity and confidentiality between the app and back-end servers. Using https is an essential step of protecting data sent over a given network. It protects it against tampering and interceptions by unauthorized third-parties. In addition, API keys must be managed securely. Avoid embedding them in the app’s code or storing them in insecure locations. Instead, use secure storage mechanisms and ensure API keys are rotated to minimize the risk of unauthorized access.

Regular code reviews and audits: importance of peer reviews and automated tools

Regular code reviews and code audits are crucial requirements for ensuring high security standards throughout the app’s lifecycle development. Peer reviews involve other developers examining the code to identify flaws, bugs, and incompliance with security standards. This collaborative approach ensures identification of issues that individual developers might miss. Besides manual reviews, automated tools may help to scan the code for vulnerabilities. It may also help enforce coding standards and checking for common security issues. Tools like static application security testing SAST and dynamic application security testing DAST automate the identification of security flaws.

Authentication and Authorization

Implementing biometric authentication: using face ID and touch ID

Biometric authentication leverages unique physiological features of humans. These features include: facial expressions for the face ID and fingerprints for the touch ID. Physiological features are used to provide a highly secure and convenient way of authentication. Implementing these features in iOS provides a safer app experience as it ensures that only authorized personnel of these apps can access specific information or features. For instance, Apple’s Local Authentication framework simplifies the integration of biometric authentication in apps. This allows developers to easily prompt their target users for either face ID or touch ID when using the app.

OAuth and OpenID Connect: secure authentication protocols

OAuth and OpenID are industry-standard protocols for secure authentication and authorization. The former provides a protocol for delegated access. It allows app users to grant third-party apps access to only a limited access to their resources without accessing crucial and sensitive information. On the other hand, Open ID Connect which is built on top of OAuth 2.0 adds a layer of protection which is an identity layer. This allows the app to verify the identity of the user by looking at their basic profile information. Implementing these protocols ensures that authentication processes are secure and robust, thus reducing the risk of credential theft and unauthorized access.

Role-based access control: managing user permissions effectively

Role-based access control (RBAC) is a popular mechanism of managing user permissions effectively in an app. With RBAC, access rights are granted based on the roles assigned to individual users. This ensures that users have only information and access rights for their roles. This role-based access control minimizes the risk of unauthorized access to protected or sensitive information. Implementing RBAC means effectively defining roles and permissions and enforcing them throughout the app’s security policy. For instance, in an e-commerce app, users may include: vendors, administrators, and users with roles and permissions granted according to each person’s needs. By effectively managing user permissions, developers can ensure that the principle of least privilege is enforced. This helps enhance overall security.

Data Encryption

End-to-end encryption: protecting data during transmission

End-to-end encryption (E2EE) is a crucial step of protecting data during transmission as it’s moving from the sender to the recipient. This encryption ensures that only the communicating persons can read the messages being transmitted. In the context of iOS, implementing end-to-end encryption means that information moving from the app to the backend servers is fully encrypted. This is done so that even if it’s intercepted, unauthorized users cannot decode the message. This is usually achieved through robust encryption protocols such as Transport Layer Security. By enforcing E2EE developers can ensure that sensitive information like personal names and financial transactions are protected against intrusion or third-party unauthorized access.

Encrypting sensitive data: best practices for data at rest

Encrypting data is a crucial step of protecting and safeguarding information stored inside a device. This includes: user data, application information, and any other piece of information or data that shouldn’t be accessed by unauthorized users. Best methods of protecting data at rest involve using robust encryption protocols such as Advanced Encryption Standard AES and using the built-in encryption features of IOS. Apple provides robust encryption protocols. These protocols include: data protection APIs that help developers specify different levels of data protection standards based on the sensitivity of data. This means that even if the device is stolen or lost, it doesn’t release sensitive information without correct authentication credentials.

Using iOS crypto libraries: using commoncrypto and security framework

iOS provides robust and scalable crypto libraries such as commoncrypto and security frameworks. These frameworks help developers with encryption, decryption, and common cryptographic operations within their applications. For instance, commoncrypto contains a wide range of cryptographic functions, including hash functions, symmetric key encryption, and HMAC (hash-based message authentication code). On the other hand, the security framework extends these capabilities by providing high-level functionalities for certifications, secure storage, and managing keys. By using these encryptions, developers can leverage different encryption schemes that are tailored to their app’s functionality.

Secure Data Storage

Keychain for sensitive data: storing data and tokens securely

The iOS keychain is a secure storage service provided by Apple. It is designed to store small quantities of sensitive information such as tokens, passwords, and cryptographic keys. It’s highly advisable to use the iOS keychain to store sensitive information as it’s considered highly robust and well-secure. Its robust security features include: automatic management of permission-based controls and hardware-backed encryption. Data stored on the chain is only accessible through a key stored in the app. This key ensures that even if the device is compromised, the data remains safe and secure. The keychain further entails sharing credentials across multiple apps developed by the same team. This enhances seamless collaborations and teamwork.

Core data and SQLite encryption: encrypting databases within the app

For applications that require storing large amounts of data, SQLite and Core data are the mostly used databases in the iOS ecosystem. However, storing data in these applications without encryption can potentially expose your data to unauthorized access if your device is compromised. To mitigate this risk, developers should encrypt their Core data and SQLite databases. One approach of doing this is by using SQLCipher which provides transparent encryption for SQLite databases. By encrypting database files, developers can ensure that even if the hardware is compromised or the physical devices accessed without permission, the data remains secure. This encryption must be coupled with secure key management practices like storing IOS keys in the iOS keychain.

NSFileProtection: protecting files stored by the app

The NSFileProtection is a feature provided by Apple that allows developers to specify different levels of security for files stored in their apps. By applying appropriate NSFileProtection attributes, developers can decide when files can be accessed depending on the phone’s lock state. The most secure option is the ‘NSFileProtectionComplete’ which ensures that all files are inaccessible when the device is locked. This means that even if the device is lost or stolen, the stored files cannot be accessed without the correct authentication credentials. The user will have to authorize their files to be accessed. Using NSFileProtection ensures that all files are protected such as cached data, configuration files, and user documents.

Network Security

App Transport Security ATS compliance: ensuring all connections are secure

App Transport Security is a feature introduced by Apple to enforce secure connections when information is transmitted from the app to backend servers. The ATS requires that all apps use HTTPS instead of HTTP to ensure that all data is encrypted during transmission. This form of end-to-end encryption prevents eavesdropping, interceptions, tampering, and any forms of interception. To fully comply with ATS, developers must ensure their servers are compatible with or support TLS 1.2. ATS compliance is mandatory for apps distributed throughout the App Store, making it a crucial aspect of network security.

Certificate pinning: prevent man-in-the-middle attacks

Certificate pinning is a security technique that prevents man-in-the-middle (MITM) attacks by associating a specific server’s certificate with the app. This means that the app only recognizes and trusts the server’s certificate. Any attempts to intercept or spoof the communication with a forged certificate will result in detection and blockage. Implementing certificate pinning involves embedding the server’s public certificate within the app and comparing it to the server’s certificate during each connection. If the certificates do not match, the connection is disconnected. It’s important to note that while certificate pinning adds a lot of advantages and benefits, it needs careful management. This is so especially during certificate renewal to avoid unnecessary network disruption or interruptions.

Secure socket layer and transport layer security: importance of updating security protocols

Secure socket layer (SSL) and its successor transport layer security (TLS) protocol are security protocols designed to protect data transmitted over large networks. Leveraging advanced versions of these protocols is crucial for protecting against known vulnerabilities and ensuring robust encryption. TLS 1.2 and TLS 1.3 are the latest standards. They offer better security features than the older versions SSL 3.0 and TLS 1.0. Developers must configure their servers to use the latest protocols, TLS 2.0 or TLS 3.0 and disable outdated versions. This upgrading or reconfiguring ensures the app’s data transmissmission are protected by strong encryption algorithms. It also ensures resilience against modern attack vectors.

Android App Security Best Practices (2024 Guide)

June 3, 2024/0 Comments/in 2024 mobile app trends, App Design/by NS804 Content

Security breaches on mobile devices cost trillions of dollars, causing businesses to suffer trillions in losses today. A single security breach can lead to the death of a company owing to loss of trust and legal repercussions. Android developers today must implement the highest possible levels of security measures to protect their apps from existing and evolving threats.

Regulators in many jurisdictions worldwide are implementing stricter standards in data protection. A reputation for high-security standards can give a company an edge over its competitors. Therefore, there is an incentive to implement world-class security measures. This post highlights the best practices in Android app security implementation.

HTTPS Network Connections

A lot of security breaches happen when data is in transit. Important details such as login credentials and financial information, are targeted at this point. By using a HTTPS protocol for network connections, a developer is assured of encryption of all data passing between the app and the server. If there are any hard-coded links in your app, they should all be updated to rely on the HTTPS protocol. This way, you can build trust in your app among the customer community. It is also crucial to have an SSL certificate for the application.

Secure Authentications

Today there are numerous options developers can choose to strengthen the authentication process on their app. The first option is to implement two-factor authentication where a user first enters their password, which triggers the app to send a code sent as a text message or an email. The user is requiring entering the code before gaining access to the app. Biometric authentication could also help to increase the security of an app while also smoothing out the user access process because it is faster than two-factor authentication.

Android Application Sandbox

The Android Application Sandbox environment allows containerization of apps to they do not interact or share resources. Each app has a unique ID with specific privileges and limited interaction with the operating system. The environment also allows for auditing of every app’s activity for detection of suspicious activity.

When building an app, developers must ensure the app data is not available to the ‘world’. In situations where an app needs to share data with another app, the use of a content provider would be a better implementation. Developers should follow existing guidelines for sharing different file types within the Android sandbox environment.

Carrying Out Proper Testing

Before an app is published, the development team should conduct rigorous testing both manually and with the use of automated tests. Automated tests can be done to help assess the overall vulnerability of the app and the recommended fixes. Penetration testing can be done by an ethical hacker to test how well an app can withstand threats such as social engineering. Experienced development teams are well placed to pre-empt the nature of threats an app can based on the nature of information it will access normal use.

Least Privilege

In cases where an app requires access to sensitive information or other features on user devices, the app should request access to only what is necessary. The least privilege approach minimizes the risk of information leakage. It is also best practice to activate runtime permissions, whereby an app expressly requests a user to grant access via a pop window on the screen. Developers should be keen to explain clearly why the app requires such permissions. UI writers can help write the right copy to avoid over complicating the app for users.

Safe Code Practices

The choice of an untrusted API can easily compromise the integrity of an application. Developers must use trustworthy APIs in their projects.

Another best practice is to validate user input because they are a regular source of malware attacks. Input validation involves checking the format, length, and type of input data coming from users to ensure it matches what is expected. Sanitizing user input is equally as important as validating it.

Implementing role-based access helps to limit access to sensitive data on an app based on user roles. The creation of roles and privileges has to be well-thought-out during the design phase of app creation.

Third-Party Libraries

While third-party libraries are great for faster and easier functionality implementation, they should be used with caution. Developers should rely on libraries with good documentation and a strong user community where issues around security vulnerabilities are likely to be well discussed. A thorough security analysis of all libraries a developer intends to use is a good best practice.

Code Obfuscation

Code obfuscation is done for several reasons in software development. In many cases, it happens to protect intellectual property in cases where a third party may try to rewrite the code and recreate a software program. Developers will use an encryption tool so that the code becomes unreadable. In simpler cases, the team may simply replace any metadata that contains sensitive information and replace variable names with random ones while maintaining the functionality of the code.

One of the most popularized incidents of data breach happened in 2016 whereby the personal details of 600,000 Uber drivers were exposed. This happened after developers uploaded code on GitHub containing credentials to access cloud hosting accounts on AWS. This goes to show the importance of obfuscation and why overlooking it could result in massive reputational damage even for a large company.

Creators of malware also tend to use obfuscation to make their programs hard to decrypt.

Regular Updates

Frequent app updates are important to secure an app from evolving security threats. Developers have a role to remain in touch with developments in-app security and how best to keep out threats. One of the best ways to ensure users keep updating their apps is to send push notifications to prompt. Adding new features regularly also makes users excited about downloading updated versions of an app. The best practice is to ensure that the app is using all the latest and most secure versions of its dependencies.

Constant monitoring and logging of activity on the server side helps to detect incidents or anomalies in user activity. App developers must respond promptly to such threats.

Understanding Android App Security-Related Laws

Any development team in 2024 must strive to understand the data protection and user privacy laws in their jurisdictions. The EU’s GDPR set a high bar for compliance which many other countries follow. So far, both Meta and TikTok have received hundreds of millions of dollars of fines for various contraventions of privacy laws in Ireland where GDPR is applicable. Serious offenses can result in penalties of up to 20 million euros or 4% of company revenue, whichever is higher.

Fortunately, there are concerted efforts, especially by cloud service providers to help development teams and businesses comply with these laws.

Still, businesses are expected to have a clear privacy policy available for users. A privacy policy will normally explain how businesses use the data they collect from users and how well they handle it.

Diligent Error Handling

Improper messaging in case of an error, while an app is in use, can lead to inadvertent disclosure of sensitive system information. Such information can be used for malicious intent. Messages shown to users should be written with this in mind. It is also a best practice to log all errors for further analysis and resolution. In fact, for major applications, there should be a dedicated team to ensure all incidents are well analyzed. It is not enough to fix the error. The team has to assess the impact of every incident.

Proper Session Handling

Poor session handling can lead to potential session hijacks on applications. This is why banking apps or payment wallets require users to sign in again after a brief period of inactivity. Developers should use session timeout effectively on their apps. Having to sign in many times can be disruptive for users but it is imperative for any apps that carry valuable user information that is an easy target for hackers.

Secure Data Backup

Most apps today are hosted on the cloud, thus limiting the size of apps on devices. This is a great practice because it makes storage cheaper and safer. Developers should choose the correct data-redundancy option depending on the value of their data. In the case of an attack or other unforeseen events, the organization can always recover data. In situations where data synchronization between app and cloud data does not happen in real time, backups should be scheduled to happen as often as reasonably possible.

Secure Development Training

Continuous training is necessary for developers to build safe Android apps. Software development teams need access to learning materials covering emerging app security trends. There is a need to focus on app security testing, debugging, and even disaster management. Team members should appreciate the true cost of data breaches to an organization and to end users when personal information is in the wrong hands.

A data breach at Marriott International Inc. in 2018 was estimated to have cost the company over $200 million. Over 500 million hotel guests had their personal information exposed. The model used to estimate the cost considered costs of notifying the guests, credit monitoring, replacement of cards, forensic work, and credit monitoring. Credit monitoring involves looking out for evidence of fraudulent credit activity following a breach. The model used in Marriot’s case did not take into account potential fines for contravening GDPR and other privacy laws.

Training should happen regularly in software development teams because of the speed with which new threats keep emerging. Fortunately, a lot of training resources are available for self-paced learning.

Choosing an Android App Development Partner

As seen, there are numerous best practices developers must adhere to when building Android applications. These recommendations have emerged over time as technology evolves and attackers find new ways to target applications.

The use of cloud storage today, for instance, is preferred over local data storage because the latter is an easier target for attacks. Installing external devices to expand device storage capacity and copying app data there creates clear security concerns. The external storage device can be easily lost or stolen and accessed by a third party. As such, app data today should ideally never be stored on an external storage device such as a memory card.

Man-in-the-middle attacks exploit vulnerabilities in the transport layer of most apps. Proper encryption of information through the choice of correct network protocols is vital for data protection. Rigorous penetration testing and other forms of testing are quite important for ease of mind regarding an app’s security robustness.

By working with the right app development partner, you can build and implement a proper security strategy for your Android application. App security ought to start during the design phase and should not come as an afterthought. Our team understands this and implements best practices such as user input validation and sanitization throughout the app. The choice of libraries, APIs, and all app dependencies is well thought out before the code is written.
