Question

I am developing a memory game, in which I want to play background music while starting the game.

I used sound pool class and successfully executed it, but I have problem in playing. I added .mp3 audio file of two minutes, but it’s playing only for 15 seconds more.

Can anyone say what problem I have? This is my soundclass file:

public class Soundclass {
    private SoundPool soundpool;
    private HashMap<Integer, Integer> soundpoolmap;
    private AudioManager audiomanager;
    private Context context;

    public void initSounds(Context thecontext) {
        context = thecontext;
        soundpool = new SoundPool(4, AudioManager.STREAM_MUSIC, 100);
        soundpoolmap = new HashMap<Integer, Integer>();
        audiomanager = (AudioManager) context
                .getSystemService(Context.AUDIO_SERVICE);
    }

    public Soundclass() {

    }

    public void addSound(int Index, int soundID) {
        soundpoolmap.put(Index, soundpool.load(context, soundID, 1));
    }

    public void playSound(int Index) {
        float streamVolume = audiomanager
                .getStreamVolume(AudioManager.STREAM_MUSIC);
        streamVolume = streamVolume
                / audiomanager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
        soundpool.play(soundpoolmap.get(Index), streamVolume, streamVolume, 1,
                0, 1f);
    }

    public void playLoopedSound(int Index) {
        float streamVolume = audiomanager
                .getStreamVolume(AudioManager.STREAM_MUSIC);
        streamVolume = streamVolume
                / audiomanager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
        soundpool.play(soundpoolmap.get(Index), streamVolume, streamVolume, 1,
                -1, 1f);
    }

}

and i used this class for given activitycalss .in oncreate function

Button btn = (Button) findViewById(R.id.sound);
        soundclass = new Soundclass();

        soundclass.initSounds(getBaseContext());
        soundclass.addSound(1, R.raw.jinglebells);

        btn.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

                soundclass.playSound(1);

            }
        });

Soundpool is not meant to be used for background music. It has many limitations such as file size loading and playing time. It’s mainly used for sound effects.
Use the MediaPlayer class for background music.
