Adding sound to the Pong game

Copy the assets folder and all its contents from the Chapter 11 folder of the download bundle. 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 use the project explorer window in Android Studio to view the assets folder you 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 int mBeepID = -1;
private int mBoopID = -1;
private int mBopID = -1;
private int mMissID = -1;
