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.

Testing the game so far

Running the game still produces a blank screen but it is well worth running it to see whether there are any problems before you proceed. Just for fun, you could test SoundEngine by adding this temporary line of code to the onTouchEvent method:

@Override
public boolean onTouchEvent(MotionEvent motionEvent) {
      // Handle the player's input here
      // But in a new way
      mSoundEngine.playShoot();
      return true;
}

Every time you tap the screen, it will play the shooting sound effect. Delete the temporary line of code and we will move on to making our game engine begin to draw things too.
