Android : how to use soundpool for looping sound in android

i want when my app open , play a sound and this sound repeat unlimited . i want use soundpool because mediaplayer have delay for every repeat . i use this code :

soundPool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);
    soundID = soundPool.load(getApplicationContext(), R.raw.b, 1);
        soundPool.play(soundID, 1, 1, 1, -1, 1f);  

but this code not play sound . in examples i want remove this code :

@Override
    public void onLoadComplete(SoundPool soundPool, int sampleId, int status) {
        loaded = true;
    }

its possible ? because i have more sound to play .
