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.

Adding sound to the Pong game

Copy the assets folder and all its contents from the Chapter 11 folder on the GitHub repo. Now use your operating system's file explorer to navigate to the Pong/app/src/main folder of your project. Paste the assets folder and its contents.

Obviously, feel free to replace all the sound effects in the assets folder with your own. If you decide to replace all the sound effects, make sure you name them exactly the same or that you make appropriate edits in the code that follows.

Notice that if you look in the project explorer window in Android Studio, you can view the assets folder and can see that the sound effects have been added to the project:

Let's write the code.

Adding the sound variables

At the end of the member variable declarations, before the PongGame constructor, add the following code:

// All these are for playing sounds
private SoundPool mSP;
private...
