In-Depth Information
Next, we have a mysterious method called reload() . Remember that the OpenGL ES context
will get lost when our application is paused. We have to reload the textures when the application
is resumed, and that's exactly what this method does. We also resume the music playback in
case sound is enabled.
public static void playSound(Sound sound) {
if (Settings. soundEnabled )
sound.play(1);
}
}
The final method of this class, playSound() , is a helper method we'll use in the rest of the
code to play back audio. Instead of having to check whether sound is enabled everywhere,
we encapsulate that check in this method.
Let's have a look at the modified Settings class.
The Settings Class
Not a lot has changed in the Settings class. Listing 9-2 shows the code of our slightly modified
Settings class.

highscores[i] [i] = Integer. parseInt (in.readLine());

// :( It's ok we have defaults
} catch (NumberFormatException e) {
