Learning Java by Building Android Games - Second Edition

By: John Horton

Overview of this book

Android is one of the most popular mobile operating systems presently. It uses the most popular programming language, Java, as the primary language for building apps of all types. However, this book is unlike other Android books in that it doesn’t assume that you already have Java proficiency. This new and expanded second edition of Learning Java by Building Android Games shows you how to start building Android games from scratch. The difficulty level will grow steadily as you explore key Java topics, such as variables, loops, methods, object oriented programming, and design patterns, including code and examples that are written for Java 9 and Android P. At each stage, you will put what you’ve learned into practice by developing a game. You will build games such as Minesweeper, Retro Pong, Bullet Hell, and Classic Snake and Scrolling Shooter games. In the later chapters, you will create a time-trial, open-world platform game. By the end of the book, you will not only have grasped Java and Android but will also have developed six cool games for the Android platform.

Chapter 11. Collisions, Sound Effects and Supporting Different Versions of Android

By the end of this chapter, we will have a fully working and beeping implementation of the Pong game. We will start the chapter off by looking at some collision detection theory which will be put in to practice near the end of the chapter. We will also learn about how we can detect and handle different versions of Android. We will then be in a position to study the SoundPool class and the different ways we use it depending on the Android version the game is running on. At this point, we can then put everything we have learned into producing some more code to get the Pong ball bouncing and beeping as well as put the finishing touches on the game.

In summary, we will cover following topics:

  • Study the different types of collision detection

  • Learn how to handle different versions of Android

  • Learn how to use the Android SoundPool class

  • Finish the Pong game

Mind your head!
