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.

Android or iOS Development – Which Costs More?

/0 Comments/in , , , /by

A report by Top Design Firm states that almost two-thirds of enterprises that developed a mobile app for less than $30,000 (63%) were exclusively for android applications, compared to 41% of companies that developed IOS apps. Top Design Firms surveyed managers and small businesses to determine the cost of developing both the IOS and android applications. The data shows that it is cost-effective and way cheaper to develop for Android than IOS. In addition, it was cheaper to outsource the app development services than to conduct in-house development.

The exact cost of android or IOS app development varies significantly based on each enterprise location and needs. Dawei Lei who’s the outsourcing director for Aloa.com states that developing for android provides massive cost savings while IOS apps have better inclusion in the App Store.

Below we examine why android and IOS app development costs differ and their respective cost drivers.

IOS Development

Apple’s flagship and iconic mobile operating system has inherent benefits. Granted, due to its reputation in the US and across Europe, your business can leverage returns on investment in these regions. The spending habits of this demographic guarantees a higher ROI.

Premium value

With IOS development, you take a bite of that juicy apple and enjoy a western audience. And while you’ll enjoy the value and thrill of a reputable brand, you’ll also be expected to spend substantially more on this inner circle. IOS apps can be written in Objective-C or Swift which both come at a premium cost. In some cases, IOS mobile app development costs can reach 15% more than their java counterparts.

Top minds

In every mobile app development exercise, skills are a must, together with tight app development requirements and considerable restrictions on what you can or cannot add to the IOS environment. Developers will need specialized software such as XCode. Not only does this app come at a premium, it runs exclusively on Mac. App software is such that if you’re looking to develop for iPhones, you will need another piece of technology to support this addition. So, IOS apps are considered well-crafted by highly skilled specialists.

Skilled but manageable condition

IOS has strict operating conditions but is possible to manage. As a first-time developer, you can face redevelopment costs when carrying out app launches due to errors in the production criteria. Missed production criteria can be due to Apple App Store’s tendency to reject applications deemed unusable or irrelevant. The benefit is that there is a limit to the number of software updates. With IOS irregular updates, it’s possible to gain traction with your creations and develop an app that’s relevant for a long time. Apple tends to reject support for old software, meaning that new apps must respond to the emerging needs of new users – nothing archaic!

Limited customization

IOS can present limitations in terms of how many updates it can support and how many features it can add. IOS can also present issues on the ability to customize an application’s interface. In this case, it’s impossible to apply additional features if they need interaction with third-party software. Ultimately, these unwanted limitations can be beneficial, which can shorten development time considerably.

What will you get with IOS app development?

  • Exploring western and US markets – If your business has a special interest in European and the US markets, IOS apps will be a clear winner here.
  • Monetization based on direct charges – IOS device users statistically spend substantially more than android users. If you’re planning to create a paid app or to monetize your app through in-app purchases – IOS is ultimately the winner. App Store’s revenue is much higher than Google Pay even though Google Play triumphs twice in app downloads.

Android Development

Android is the most popular mobile application and it spans the whole world, in any language. Among its most popular markets in Australia, Africa, and Asia. Android allows you to explore a wealth of opportunities worldwide, with flexibility and convenience in the world’s genuinely affordable OS.

Universally affordable

New mobile applications are developed using Kotlin, with Java still famous for carrying out long-running development projects. However, even long-running projects are migrating to Kotlin as transitions are difficult to undertake. With Kotlin, developers are expected to pay a one-time fee of $25.

Average expertise

Expertise is needed in android-supported applications, but without diving into complex projects. The versatility of working with android is thanks to the wide availability of free-to-use information, which keeps cost to a minimum. Google offers an extensive knowledge base to developers, including interactive materials, practical exercises, and the entire training modules for every level of developer.

Highly flexible

Kotlin and Java are versatile programming languages supported by Linux, Windows, and Mac OS. This allows developers to execute Android apps regardless of their machine’s OS. However, as there is a wide range of Android endpoints in circulation, you can encounter compatibility issues for specific technical functions. For example, apps designed with fingerprint scanners may not be featured in the device of end-users.

It’s important to note that this flexibility presents serious issues to some legacy systems. With Android offering support for software versions ranging back to 2012, your application may need adjustments to work with a long list of problematic software versions. This way, the cost of app development may go up as the need for continuous development arises.

Easy customization

Android extends a world of personalization to programs, thanks to market ubiquity. Android changes are due to the multitude of devices using Android. The drawbacks of this are a diverse set of specifications across multiple handset brands. With different screen sizes from different manufacturers, developers must support a list of consumer segments.

What will you get with android app development?

  • Dominates Africa, Australia, and Asia – Android holders outnumber IOS holders worldwide, heavily dominating in Asia, Africa, and Australia.
  • Monetization is based on advertising – Android users have a lesser will to pay for mobile applications, partly because of overall income levels and payability. If you plan to design a free app and you want to monetize your application by advertising – Android is a solution here.

Android vs. IOS – Final Cost Verdict

While IOS offers a sleek development environment replete with rules of engagement, it has far less customization. Precisely, the skill set required raises development expenditure. However, later development stages can lead to lower expenses in the medium term, as the development environment is less prone to complications.

Android app development presents lower entry barriers, unlimited personalization options, and a wealth of development information. These factors are what keep the costs down especially in the immediate term. Where expenses diverge from the IOS, they can emerge in later development phases, involving re-development and testing to attain its substantial user segment.

Ultimately, both operating systems work out to be effectively the same. Each aspect accounts for the labor and time costs involved in developing the application. When looking to optimize costs, consider outlining your app’s objectives early and budgeting your time well. You may not be able to change your IOS or android app but your approach needs to be more proactive and profitable.

 

Intro to Android App Development

/0 Comments/in /by

Android is a reputable computing platform that is based on the popular Linux operating system. The initial android version hit the market in 2008 in the form of a mobile phone platform, at a time when the most popular mobile phone was a Blackberry, when Apple was making waves across different sectors.

For over ten years since it was first released, Android has effectively earned the most popular operating system by several measures. Despite the flashy brand and unmatched capabilities of the popular iPhone platform, Android global shipments meaningfully outpace Apple’s offerings – a clear indication of the potential of Android in the OS market.

Learning Android app development may seem like a daunting undertaking, but it can bring a world of possibilities, especially if done well and diligently. You can create the next “hit app” that will change the way we interact or work. By learning android app development, you could gain some skills that could land you a great job, or develop a tool that you can use to improve your workflow.

So, let’s jump right in on how you can develop an Android app.

  1. Download the tools you need for android app development

Firstly, you need to create your development environment. This is to ensure your desktop and workstation set-up support your android app development goals. For that, you will require Android SDK and Android Studio. Luckily, the two come packaged as a single download, and you can always access it anytime.

Android Studio is an integrated development environment IDE. This is essentially a platform where you can enter your code (primarily Kotlin or Java). It’s where you access all the necessary tools for development. Android Studio allows you to access APIs and libraries from the Android SDK, thereby giving you unlimited access to native development functions of the Android OS.

  1. Start a new project

Once you have successfully installed Android Studio on your desktop, now it’s time to initiate a new project. While this is a straightforward process, you will need to make some serious decisions that will impact your android app development journey going forward.

Go to File>New>New Project you will select a Project Template. The template defines the UI elements and the code present in your application when it loads.

  1. Kotlin vs. Java

One of the critical decisions you’re going to make as an android app developer is whether you will learn Java or Kotlin. Both languages are officially supported by Android and Google Studio, but they have some distinct variations. Google has supported Java for the longest time. It’s what developers have been leveraging to craft Android apps for decades.

  1. Minimum SDK

Additionally, you will need to consider your minimum SDK. This refers to the lowest version of Android that you want your app to support. The lower the SDK, the highest number of audiences or users that your app will target. Kindly keep in mind that there is a relatively lower adoption rate for the latest Android versions, so sticking to the latest Android version will prevent many users from trying your android creation.

  1. Familiarize yourself with the files

You’ll be baffled by the large number of files when you try android development. When you load Android Studio, you will be surprised at just how many different types of files there are. There are different files, multiple code layers, folders, and many more. This new realization would be miles away from the single blank file you’re used to working with QBasic or Python.

  1. Test your app

The first thing to do when familiarizing yourself with any new programming language is to create an application that says, “Hello World.” Thankfully, this is an easy step in any development exercise. If you look at the XML, you’ll notice a small label that reads: Hello World!

Learning Android App Development

When embarking on your first android app development project, remember that the key is not to learn all of Android app development but to set your sights on a realistic first app development project. You will keep learning as you add new features and as you try new things. Having a goal will keep your learning process focused and structured. And before you know it, you’re an expert.
