Unloading Sounds

The app works, but you still have some cleanup to do. To be a good citizen, you should clean up your SoundPool by calling SoundPool.release() when you are done with it. Add a matching BeatBox.release() method.

Listing 19.7  Releasing your SoundPool (BeatBox.java)

public class BeatBox {
    ...

    public void play(Sound sound) {
        ...
    }

    public void release() {
        mSoundPool.release();
    }

    ...
}

Then, clean it up when you are done with it in BeatBoxFragment.

Listing 19.8  Releasing your BeatBox (BeatBoxFragment.java)

public class BeatBoxFragment extends Fragment {

    ...

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        ...
    }

    @Override
    public void onDestroy() ...
