The Ultimate Guide For Android Mobile App Development Basics

/0 Comments/in , , , , , , , , /by

Mastering the Android platform as a developer always starts by comprehending the mobile app development basics. And that’s because the Android development ecosystem is incredibly dense and complex. Consider that it’s necessary to know two programming languages for this platform: Java and Kotlin. And while some programmers may scoff at the idea of familiarizing themselves with both languages, it’s a necessary step.

But why should programmers go to such lengths when it’s possible to develop Android apps if they only know one of these languages? That’s because it’s good practice to update apps regularly. And after a certain period, it’s essential to modernize apps, which may include moving from a dated programming language to a current one. Thus, developers planning to update Android apps should have the knowledge and skills to port these from the older Java code to the newer Kotlin codebase.

Sometimes, it’s necessary to know additional languages, such as C#, JavaScript, or even Python, for cross-platform development. And with such a large variety of programming languages, developers also have to deal with many integrated development environments (IDEs) and software development kits (SDKs).

Then, the types of apps developers make will impact tooling choices. For example, making a short-form video app like TikTok will require a different toolchain to a battle royale game such as Fortnite. And if developers wish to include networking features, considerations regarding backend and integration systems become paramount.

With so many considerations, Android development seems harrowing, especially for newcomers. That’s why we’ve compiled this handy guide to help aspiring and even seasoned developers understand Android mobile app development basics.

Android Mobile App Development Basics: Choosing The Right Development Environment

So you’ve taken the time to research the market and are now busy planning your mobile app strategy. However, you’ve yet to pick your development environment, which will play a crucial role in determining the overall development experience. It may even impact the success or failure of your upcoming app project, so research all the development environments thoroughly before settling on one.

But what do you even pick with so many Android development tools available? If you’re planning on making a native app, then Android Studio is a great choice. It’s Google’s official and recommended IDE and features the Jetpack Compose user interface (UI) designer, Android Emulator, and intelligent code editor. Also, you’ll need to download the Android SDK, NDK, and Java SE Development Kit (JDK).

But if you’re planning on making a cross-platform or hybrid app, you may want to consider another development environment. There’s Visual Studio with Xamarin for cross-platform apps with native performance. And then, there’s Flutter and React Native for making impressive-looking hybrid apps.

If you decide to make a mobile game, you’ll want to use a game engine such as Unity or Unreal Engine. Both engines provide their own asset content pipelines and tooling for creating animations, levels, and visual effects. However, Unity and Unreal recommend and offer a download pathway for the Visual Studio IDE for coding.

Gaining Programming Language Proficiency 

If you’ve picked Android Studio, you’ll need to gain proficiency in both Java and Kotlin. But if you’re a new developer, start with Kotlin since it’s a more modern language with a better and more streamlined syntax. If you already have experience in Java or any object-oriented language from the C family, it should only take several weeks to learn Kotlin.

But it’s also crucial to become proficient in JavaScript Object Notation (JSON) and Extensible Markup Language (XML). JSON is a file type based on an open standard used for parsing and storing data objects. XML can also parse, structure, and manage data but can’t perform computing calculations.

For the majority of Android app development scenarios, Java, Kotlin, JSON, and XML should suffice. But what if you already have C or C++ proficiency and want to develop Android mobile games? The good news is that Google offers the Android Game Development Kit (AGDK) for developers with C/C++ skills. It’s a comprehensive suite of libraries and tools with easy integrations for game engines, such as Unity. 

And on the subject of Unity, if you opt for this engine, you may want to use the C# programming language. If you already know Java or Kotlin, C# is easy to pick up and start making simple games within days. Moreover, Unity provides many in-depth tutorials and programming resources to help newcomers become proficient with C#, the game engine, and mobile app development basics.  

How To Structure A Basic Android App’s UI With Jetpack Compose

Google recommends that developers use the Jetpack Compose UI framework for making modern Android apps. And that’s because it simplifies the creation of UIs with dynamic animations, styles, and themes. Its composable functions make it easy to change states and add images, texts, lists, grids, and scrollable columns. 

A few neat features of Jetpack Compose, which should also excite UI/UX designers, are its Material Design and Material Theming. These allow designers to make their apps more accessible and attractive to a larger demographic of users. Designers can alter all aspects of an app’s UI, from its typography to its colors. 

And some of the more advanced features of Jetpack Compose allow smooth navigation between screens, navigation across multiple screens, and passing of data between screens. With the proliferation of foldable Android smartphones, designers must take advantage of the additional screen real estate as efficiently as possible. 

One way to do this is by creating an adaptive app featuring dynamic navigation. This approach allows the app’s UI to transform elegantly and fluidly for any screen size, orientation, form factor, and device type. Moreover, there’s no loss or degradation of usability of the app, regardless of these changing factors.

Understanding Persistent Data On Android

It’s necessary to read, store, and manipulate data between an app and a relational database, such as SQLite. And that’s because you’ll need to store all kinds of app and user data and do so securely. But setting up a database and dealing with so much data can be difficult, especially for those getting to grips with Android mobile app development basics.

However, one of the most useful Kotlin APIs for this purpose is Room, which is part of the Jetpack library. It acts as an abstraction layer for configuring SQLite databases and reading, manipulating, and querying stored data. 

Sometimes, it’s more sensible to store user data and preferences on the device instead of a relational database, especially if the app will predominantly operate offline. DataStore is yet another Jetpack tool but meant for smaller datasets, such as typed objects or key-value pairs. Another benefit of DataStore is that it performs asynchronous operations but can also perform synchronous operations. This helps deal with legacy codebases designed for handling data and disk I/O operations in a synchronous manner.

5 Android App Development Myths, Debunked

/0 Comments/in , , , , /by

Whether we like it or not, development myths surround the Android platform. In a way, the Android platform is a victim of its own success, given its vast popularity. As the world’s leading mobile operating system (OS), it has evolved rapidly over the past 14 years. And with so many changes and new features introduced regularly, Android app developers have their work cut out for them.

It’s also necessary for developers to create apps that work well across a wide range of devices from various manufacturers. And there’s a need to test on more devices and spend additional time fixing bugs and patching apps.

These hoops that Android App developers have to jump through have led to several myths. One of which is that it’s far harder to develop for Android than iOS. And while there’s some truth to this, few realize that Android app development has become easier with the introduction of Kotlin and the Jetpack libraries.

But there are many more Android app development myths that we need to discuss. Read on to learn more about these myths and why we’re about to debunk them!

Myth 1: Android App Development Is Highly Profitable

During Android’s early years, many developers came on board to capitalize on this exciting new platform. And many of these developers found success, and much hype ensued about the Android platform. So much hype, in fact, that software developers specializing in other fields decided to pursue mobile app development. 

But as the platform matured and Google Play became inundated with an abundance of apps, Android app development became less profitable and far riskier. As of September 2022, the Google Play Store had over 2,6 million apps. But that’s significantly lower when the store peaked at 3,6 million apps in March 2018. 

So what does that bit of information tell us? It reveals that the golden age of Android app development has long passed. Developers and publishers have learned that it no longer makes sense to push apps onto the store on a whim. And that’s because the most successful and sustainable apps solve a problem and are high quality.

Ultimately, the Google Play Store still remains viable for those developers willing to go the extra mile. But newcomer Android developers will unlikely strike it rich with their first few apps. While there’s been a decline in apps available in the store, it’s still heavily saturated. Thus, it’s best to avoid being blindsided by claims on the internet about Android’s vast earning potential.

Myth 2: The Android App Development Environment Is Inferior To iOS

That’s completely false and may even be the other way around. Google has gone to great lengths to improve the Android app development experience, and they’ve largely succeeded. Android Studio and the accompanying App Tools truly empower developers to make some amazing apps.

And if we’re to make a quick comparison between Android Studio and Apple’s XCode, we often find Android Studio’s code editor and layout designer more useful for handling larger projects. Some developers even seem to prefer Android Studio overall, but that’s also a matter of preference.

The only major downside of Android Studio is that it consumes far more memory than it should. Furthermore, it’s often a chore to configure and deal with the Android Emulator Hypervisor Driver. And this can get rather complicated if you’re using a system with an AMD processor. But once the Android Emulator is up and running, it truly gives you a feel of how your app will run on a wide range of devices.

Myth 3: You Need To Own A Wide Variety Of Test Devices

Preferably, yes, but it’s not necessary to own many test devices. The hard truth is that you probably don’t have the resources to own a large number of devices. Moreover, it doesn’t make sense to keep a bunch of older devices with deteriorating lithium-ion batteries in your studio, as that’s a potential fire hazard.

Instead, you’ll rely on the Android Emulator to give you a broad picture of how your app will run on devices made by various manufacturers. But you’ll still need to test on actual hardware, so you’ll use all the Android smartphones and tablets your team owns. And you can take things a step further by running an invite-only beta program where users with different devices can test your app.

You’ll implement analytics in your app to collect device and performance data. And you may also run a survey where you’ll ask your users questions related to the performance and smooth running of your app. Thus, you’ll gain a clearer picture of your app’s performance on a wide variety of devices. You’re also able to pinpoint the Android versions, manufacturers, models, and configurations that impact the performance of your app long before its official launch.

Myth 4: You Need An Engine Such As Unity To Make Android Mobile Games

While Unity is a great choice for cross-platform mobile app development, you do have other options. There’s Unreal Engine if you need to create high-fidelity 3D games and AR/VR experiences. Then, there’s GameMaker and Godot if you want to make addictive pick-up-and-play 2D games.

However, if your team has the necessary skills, you may forgo a game engine. And instead, use tools and libraries such as Google’s Android Game Development Kit (AGDK). The AGDK libraries consist of the Android Frame Pacing library, Android Performance Tuner, and C/C++ game libraries. 

The latter libraries allow developers more comfortable with C or C++ instead of Kotlin or Java to create Android mobile games. And since many legacy games have been programmed in C and modern games have been programmed in C++, porting these to Android becomes a lot easier.

Myth 5: You Can Easily Release Your Android Apps On Windows 11 

Microsoft surprised everyone when they announced that Android apps would make their way to Windows 11. But it’s also one of the biggest app development myths to think this is as straightforward as it sounds. And that’s because Windows 11 users need to access the Microsoft Store and then download and install the Amazon Appstore. They’ll also need to sign in to their Microsoft Account (if necessary) and Amazon account.

That’s a very inconvenient process to gain access to Android apps only available on the Amazon Appstore. From a developer’s standpoint, it’s additional work to put an Android app onto the Amazon Appstore if it’s already on Google Play. It’s necessary to comply with Amazon’s guidelines and implement the Appstore SDK. Also, Amazon only accepts Android apps and not iOS apps, which may disappoint developers that support both platforms.

And while it’s possible to sideload Android apps on Windows 11 with Windows Subsystem for Android (WSA), it’s a complicated process. Most non-technical users will likely struggle with this; thus, the Amazon Appstore will remain the more convenient option. However, it’s a straightforward process to run Android apps from the Google Play Store on Chromebooks.

Android App Development Myths And Misconceptions

The Android platform remains exciting while offering developers the opportunity to reach over 2.8 billion users. But the popularity and overall success of the platform has led to various app development myths and misconceptions. We’ve debunked several of these, but we expect many more to make the rounds.

Questions About Android App Development? 9 Answers You Need To See

/0 Comments/in , , , , , , /by

Every appreneur or forward-looking business leader wants to know about Android app development. And that’s because Android dominates the mobile OS market, at a whopping 71% as of November 2022. With such a massive market share, it makes good business sense to push your apps onto this vibrant platform. 

And while Android plays a significant role in the mobile market, it’s also a platform that many don’t properly understand. That’s because it’s a platform that will run with Google Play Services or without if a user wants to DeGoogle their phone. In some markets, such as Russia and China, Google services are no longer an option without a VPN. 

Furthermore, Android doesn’t only run on mobile devices but also computers, game consoles, IoT devices, TVs, vehicle entertainment systems, and wearables. And since it supports such a wide range of devices, Android comes in various flavors, not dissimilar to the Linux ecosystem. While this is great and a testament to the versatility of Android, it also complicates things. 

The hard truth is that Android isn’t locked down like Apple’s iOS platform. So, there’s no simple one-size-fits-all approach here. Not that’s necessarily always the case with iOS, but it’s far less open-ended than Android. 

And given Android’s open-ended nature, this presents many challenges and opportunities. Ultimately, this will cause some to ask many crucial questions about Android app development, which we’ll answer in more detail below.

1. When Did Android Debut?

Android 1.0 launched on September 23, 2008, and was made available on the T-mobile G1/HTC Dream phone. Surprisingly, it was feature-rich at such an early stage. It featured Bluetooth, Wi-Fi, a browser, a camera, Gmail, Google Maps, YouTube, and several other applications and features.

2. Is It Similar To Linux?

Android isn’t only similar to Linux but sports a repurposed version of the Linux kernel combined with other open-source components. Google releases Long Term Support (LTS) versions of these kernels under the Android Common Kernels (ACKs) name. 

But that doesn’t mean Android apps will run on Linux and vice versa. Users will need a tool such as Anbox, which will set up a container on Linux to run Android apps. And while it’s possible to run certain Linux apps made with Java on Android, it’s a messy process that often requires cross-compilation. Understandably, this isn’t a practical solution for most Android users. 

Furthermore, not all Linux app developers will use Java but another programming language instead. So their apps will only run on an Android device via a Linux emulator, but there are no guarantees that they’ll run smoothly, fast enough, or at all. The optimal solution is for these developers to port their apps to Android and take advantage of its touchscreen functionality.

3. Is It Better Than iOS?

No. Only fanboys, platform holders, and some tech publications and journalists play favorites. As an appreneur or business leader, you only need to care about the potential of each platform. In this regard, Android offers a massive user base and a mature ecosystem that has already outpaced iOS. But that doesn’t mean you should ignore iOS, either.

4. What Tools Will I Need For Android App Development?

You will require a recent Windows, macOS, Linux, or Chrome OS computer capable of running the latest version of Android Studio. You will also need at least one test device — preferably running the latest version of the Android OS. While it’s possible to test your app using the Android Emulator (part of the Android SDK), you’ll still want to run it on an actual device.

Furthermore, you should download and install the Android SDK, Android NDK, and Java SE Development Kit (JDK). You can download Android SDK & NDK directly from Google’s Android developer portal and the JDK from Oracle. Read through the documentation thoroughly to configure all of these SDKs properly. 

While it’s possible to use other IDEs, Google recommends and officially supports Android Studio. And if you’re planning on developing native Android apps, then it’s best to stick to Android Studio in the long term. Consider using other IDEs, such as Visual Studio, if you’re developing cross-platform apps or mobile games.

5. Which Programming Languages Should I Use?

For native Android app development, choose either Kotlin or Java. But it’s preferable to go with Kotlin since Google officially supports and recommends it for modern app development. However, if you’re a cross-platform developer, you may want to go with C/C++, C#, Dart, JavaScript, or Python.

6. Which Engine Should I Use For Mobile Game Development? 

We recommend Unity since it’s the most popular, versatile, and well-supported engine for mobile game development. Also, it’s a good option for 2D & 3D game development, augmented reality (AR), and virtual reality (VR) experiences. But if you require a more heavy-duty engine for creating games with high-fidelity visuals, then you’ll need to go with Unreal Engine.

Either way, you’ll likely use Visual Studio as your IDE or each engine’s visual scripting component. If you want to use Android Studio for game development, you’ll need a game framework instead. One of the best frameworks for native Android game development is libGDX.

7. Will I Need Any Additional Tools For Game Development?

If you’re developing an intensive 3D game, you’ll probably put plenty of stress on the Graphics Processing Unit (GPU). Thus, you’ll need a way to analyze draw calls and monitor your game’s performance frame-by-frame. Luckily, most mobile GPU manufacturers and even ARM offer graphics analyzers and profilers for these purposes.

While it’s possible to ship a mobile game without using these profilers, you risk shipping it with undetected graphical issues. And given that your game needs to run equally well on devices that support different graphics libraries, such as OpenGL ES, OpenCL, EGL, and Vulkan, it’s wise to profile your app before release.

8. Should I Only Focus On Google Play Store?

The beauty of the Android platform is that you have plenty of options besides the Google Play Store. If you’re willing to acquaint yourself with the requirements and Application Programming Interfaces (APIs) of other stores, you’ll find many more avenues to reach new audiences. 

After the Google Play Store, you should consider the Amazon Appstore, which runs on Fire OS devices and even on Windows 11. And don’t forget that large smartphone manufacturers such as Samsung and Huawei have their own app stores, and both have sizable audiences.

9. How Do I Get The Most Out Of My Android App?

One of the best things about Android app development is the free tooling that’s available. And one of the best free tools is none other than Google Analytics for Firebase. The Firebase SDK will give you access to a reporting suite that allows you to monitor up to 500 pre-defined events. Moreover, its analytics reports will give you a clear picture of your app’s performance, your marketing endeavors, and user behavior.

In Conclusion

Android app development is worthwhile even though it’s complex and sometimes plagued with difficulties. But it has become easier thanks to the introduction of Kotlin and an ever-improving Android Studio and tooling. Contact NS804 if you have any more questions about Android app development and how we can help you create outstanding apps. 

What You Need Before Developing An Android App

/0 Comments/in , , , , , /by

Developing an android app requires a deep understanding of design and programming. When approaching a new technology or project, it’s advisable to break it down into pieces. If you’re an experienced website developer, many of the techniques (and tools) involved in Android app development will be synonymous with things you already know.

Building mobile apps requires the mastery of more nuanced concepts. Mobile devices have simpler processors, smaller screens, and in the case of android devices, different manufacturers. Developers should keep their codes flexible and account for various user-interface scenarios. So, what does it take to become a qualified or expert android developer?

Here’s what you need before developing your android app.

  1.   Java

Java is the best programming language that underscores Android mobile app development. For those who have gained their programming experiences from languages like Ruby and JavaScript, there can be a learning curve when using the Java programming language for the first time. Like Ruby and JavaScript, Java is object-oriented; but it’s stricter about processing different data types. Developers need to be careful with their codes by defining the different data types, using, and allocating scarce memory resources.

  1.   XML Understanding

XML is a language that defines a set of rules for encoding documents in a format that is human-readable and machine-readable. XML was created as a standard approach to encode data for internet-based mobile applications. The XML is a structured mark-up language that shares many features with HTML including; angled brackets, tag types, and the deep nesting of elements. In short, XML allows information to be conveyed between devices in a manner that can be understood easily.

  1.   Android Software Development Kit SDK

The software development kit SDK may conjure up images of a briefcase packed up with all sorts of spy tools. But in essence, it’s a fancy name for a set of pre-packaged codes. Android SDK is a module of Java code that extends developers access to mobile devices functions and capabilities like accelerometer and camera. One key element of the Android SDK is a library called Gradle. So, let’s say you want to integrate a social media platform like Facebook with your application. To do this, you’d download a code library from Facebook, then tell Gradle you’re using this code so that when your application compiles, your code remains well-organized.

  1.   Android Studio

The integrated development environment for Android developers is the Android Studio. Android Studio is designed on top of the well-respected IntelliJ IDE and comes with great out-of-the-box support for many of the most common software development kits.

Android studio also entails many features and capabilities that developers expect of a fully-fledged IDE environment. For instance, the code completion feature makes auto-complete suggestions as you type. Code debuggers help you review your code to identify sources of error.

  1.   APIs

As an android developer, you will want to interact with many other services. For instance, you may want your users to access a calendar or events sessions from a third-party service provider – or even check the stock market. An android app development company usually offers APIs and will show you exactly how to query them for data in a consistent, secure way. While you’re free to interact with an existing API, Google makes it easy to connect to their APIs using android apps. For instance, you can use Google APIs to monitor the geo-location of your users.

  1.   Database

If your app handles huge amounts of data, most likely the data won’t stay on the device for long. Instead, your app will most likely interact with a database living outside your phone. Cloud services like Parse and Firebase provide simple APIs to host data in the cloud and make it available across different devices. These cloud platforms provide Java libraries to plug in your app, making it easy to cache data on the user’s device.

This synching of data between remote database and local storage is vital if you want your users to use the app while they’re offline. So, before developing an Android app, ensure to have adequate storage. That is achieved by outsourcing cloud services that provide a simple API to secure your app’s data.

How To Become a Better Android Developer?

Becoming an Android developer is easy but being an expert developer who stands from the crowd is difficult. It takes a great deal of passion, dedication, and perseverance to become great at design and programming. So, what do you need to become a better Android developer?

  • Get familiar with android framework internals. It’s advisable to get familiar with Android’s actual framework code. Many developers are afraid of delving right into the Android framework internals. Luckily, it’s amazing how much you can discover how things work.
  • Get over the fear of missing out. Android is quite big. You cannot learn it end-to-end in a month or three months. The more you learn, the more you understand how much you don’t know. As a beginner, it’s perfectly normal to feel that you’re missing out on learning crucial information.
  • Start reading more code. Most developers don’t take the time to read what other developers are writing. Instead, they spend more time writing the codes they already know. The best way to become an Android developer is to read the excellent codes of more experienced developers.
  • Learn more languages. It’s crucial that you learn more programming languages. You need to keep yourself updated with the industry’s happenings rather than confining your thinking to the Android space. Learning more languages and opening your mind to new possibilities will inspire new ideas, open up your perspective, and help you improve your Android development skills significantly.
  • Learn Java design patterns. Learning Java design patterns is crucial in your Android development career. Whenever you’re stuck in solving programming problems, design patterns can be lifesavers. You also need to be on the same page with other designers and programmers so that when they’re talking about using a Decorator, Factory, or Façade pattern, you instantly know what they mean.
  • Contribute to open source. If you have developed a plugin, library, or any other useful piece of code, consider open-sourcing it. There’s much to learn in the process of maintaining your projects or contributing to open source projects. Contributing to open-source is an excellent crash course in open-source development that will exponentially increase your value as a developer.
  • Make your IDE work for you. Start spending more time understanding the integrated design environment you are using: Android studio. The IDE can do much more than you think. There are many cool features hidden in the IDE that most developers don’t even consider. Make it a habit to discover new and better ways of making your tools work for you, thereby improving your productivity and workflow.
