7 Skills You Need to Master to Become a Successful Android Developer

The Android operating system is the most widely used mobile OS in the world, and as an Android developer, you’ll have access to over 1 billion active users and 24 billion app downloads from the Google Play Store. These figures, coupled with research from Gartner that shows that by 2017, 1 million new Android devices will be activated every day, make the platform one of the best to develop for – but only if you’re doing it right! This article details seven skills that will help you get started on the path to being an expert Android developer.

Skills You Need to Master to Android Developer


Java is an object-oriented programming language that allows developers to build fast, scalable applications that can run on multiple operating systems. In fact, Java is already in wide use at Google and you’ll need it for any open source development. If you don’t have any experience with Java but are still interested in developing for Android devices, there are plenty of courses available online. One good resource is Coursera’s popular Learning Java by Building Android Games course. Once you master Java, then you can start learning about Android app design itself—just remember that things change quickly in tech so stay up to date as best as possible!

For simplicity’s sake, we’ll start off our discussion with Hello World. The goal is simple: display Hello World using java code from within eclipse IDE (Android Studio). Although android will allow many ways to create your application do not get too fancy or creative yet, just stick to Hello World for now.


XML, short for Extensible Markup Language, is like HTML for describing data. It’s used by many operating systems and servers, which use it to share data with other applications. These other applications may not be from Apple or Microsoft; XML is able to support multiple languages and platforms, so you can write an application in Java or C++ that reads data formatted as XML. XML is best known among developers as a language commonly used to read configuration files on Linux and Unix computers. Although they are conceptually similar, XML has more formal rules than HTML and supports schemas (similar to classes) to describe what information any given document should contain.

Android SDK

After downloading and installing Android Studio, you need to set up your development environment by updating your build tools, adding support libraries, and generating an emulator for running tests. The SDK Manager guides you through these steps. In addition, you’ll need Google Play Services for authentication and other services. There are several ways of accessing it: Platform-tools or SDK Manager on Mac or Windows; using Gradle, or using Android Studio’s new offline feature. However, bear in mind that setting up your machine is only part of configuring your Android device. You will also have to install any necessary drivers for ADB to work correctly and allow debugging over USB. Make sure you follow all instructions very carefully!


SQLite is an in-process library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. The source code for SQLite is in the public domain. In other words, you can use it freely in your commercial products with no licensing fees and no royalties; its use is not restricted by patents or any software copyright. We’ll talk about how to use SQLite databases as persistent storage on mobile devices. This post will show you step-by-step instructions for creating a basic Android app using SQLite. This post explains how to create a database in an android application using sqlite3 command-line tool.

Interface Builder

Interface Builder is an Apple tool used to design applications. Although it may not be as powerful as direct Java coding, Interface Builder allows you to drag and drop objects into your app with ease. While XML is good for configuration files, designing applications still requires some basic programming skills. Using Interface Builder is an effective way of getting started before you learn to code. It’s also great for prototyping without writing any code at all. I highly recommend that every developer master IB and learn how to use it well. The same can be said for Storyboards in Xcode on iOS or Windows Universal Designer in Visual Studio on Windows (there are similarities in functionality between all three). If you master one of these tools, then learning another will make your transition easier. On that note…


Apache Cordova is an open-source development tool that allows mobile app developers to build apps with HTML, CSS, and JavaScript. When you use Apache Cordova or PhoneGap, you’re essentially creating a hybrid app that uses web technologies but can be installed on your device and work similarly to native apps. Here are some important skills for any hybrid app developer ​ 1. Familiarity with Android SDK—the software developers kit designed specifically for Google’s operating system; understanding how it works will help you be more comfortable coding in general. 2. Programming knowledge—if you know Swift, Python, or Ruby (among others), learning Java may not seem too challenging to overcome; however, if you don’t have experience in programming languages already and aren’t sure where to start, try out MIT Code School or an online course from Udacity. 3. Knowing design principles—Designing for touchscreens is totally different than designing for desktops, so you need to understand these differences; if you’re working solo on a project, also consider consulting with someone who has previously worked as an app designer. 4. A solid idea of ​what kind of game/app you’re going to create 5. Understanding basic security procedures​


If you’re working as an Android developer, there’s no way around Git. It’s nearly impossible to get started with development without learning how to use Git for version control. Plus, it can do so much more than that—we cover 15 essential Git commands for programmers. Learn ‘em! A good start is checking out GitHub Guides, which has step-by-step guides on anything related to programming, including Git (with helpful gifs!). They also have short courses on subjects like database design and management, server maintenance and security, and testing your code. Think of them as Dev Bootcamp for self-learners. Here are some great resources for learning about git:
