Android™ How to Program, Second Edition

6.8.11. Methods stopGame and releaseResources

Class CannonGameFragment’s onPause and onDestroy methods (Section 6.7) call class CannonView’s stopGame and releaseResources methods (Fig. 6.17), respectively. Method stopGame (lines 464–468) is called from the main Activity to stop the game when the Activity’s onPause method is called—for simplicity, we don’t store the game’s state in this example. Method releaseResources (lines 471–475) calls the SoundPool’s release method to release the resources associated with the SoundPool.
