Learning Java by Building Android Games - Third Edition

Overview of this book

Android is one of the most popular mobile operating systems today. It uses the most popular programming language, Java, as one of the primary languages for building apps of all types. Unlike most other Android books, this book doesn’t assume that you have any prior knowledge of Java programming, instead helps you get started with building Android games as a beginner. This new, improved, and updated third edition of Learning Java by Building Android Games helps you to build Android games from scratch. Once you've got to grips with the fundamentals, the difficulty level increases steadily as you explore key Java topics, such as variables, loops, methods, object-oriented programming (OOP), and design patterns while working with up-to-date code and supporting examples. At each stage, you'll be able to test your understanding by implementing the concepts that you’ve learned to develop a game. Toward the end, you’ll build games such as Sub Hunter, Retro Pong, Bullet Hell, Classic Snake, and Scrolling Shooter. By the end of this Java book, you'll not only have a solid understanding of Java and Android basics but will also have developed five cool games for the Android platform.

Starting the first project – Sub' Hunter

Now we can get started on the first game. I will go into a lot more detail about what exactly Sub' Hunter does and how it is played. However, for now, let's just build something and see our first Android game start to take shape.

Important note

The complete code, as it stands at the end of this chapter, is on the GitHub repo of the Chapter 1 folder. Note, however, that you still need to go through the project creation phase, which is explained in this chapter (and at the beginning of all projects), as Android Studio does lots of work that we cannot see.

Follow these steps to start the project:

  1. Run Android Studio (if it isn't running already) in the same way you would run any other app. On Windows 10, for example, the launch icon appears in the start menu.


    If you are prompted to Import Studio settings from:, choose Do not import settings.

  2. You will be greeted with the Android Studio welcome screen...
