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.

Summary

In the second and final chapter of the Bullet Hell project, we applied the finishing touches to the game by adding timing and the Bob class.

We also dealt with initializing and drawing a bitmap to represent a game object for the first time. In all future projects, bitmaps will play a much bigger role and we will do things such as move them, scale them, rotate them, and even animate a running Bob from them.

With our new-found skills and experience, we can now cover some more important Java and Android topics, including the following:

  • The stack and the heap
  • Garbage collection (yeah, that's a Java thing)
  • Localization to add foreign language support
  • More encapsulation to keep our code from becoming too sprawling
  • Collections
  • Enumerations
  • Saving the high score forever
  • Much more Bitmap stuff
  • And more…

We'll cover all of this over the next four chapters while we build a classic Snake game.
