Soundpool sample not ready

Question

I have a .wav file that I\'d like to use across my game, currently I am loading the sound in onCreate() of each activity in the game.

 soundCoun         


        

Answer 1

The SoundPool library uses the MediaPlayer service to decode the audio into a raw 16-bit PCM mono or stereo stream which we simply can call preparation of Stream, that takes some times depending on size of sound file. And if we try to play the sound before that process is over, we get "sample x not ready" error.

There are two solutions for this

1. implement setOnLoadCompleteListener or
2. wait arbitrary amount of time so that preparation is over

and then play it Note that there is no exception for this condition or application is not crashing without any try-catch

Answer 2

This would work for you definitely !

public void playWavFile() {

    Thread streamThread = new Thread(new Runnable() {           

        @Override
        public void run() {                 
            SoundPool soundPool;
            final int wav;
            String path = "/mnt/sdcard/AudioRecorder/record.wav";
            soundPool = new SoundPool(5,AudioManager.STREAM_MUSIC, 0);
            wav = soundPool.load(path, 1);
            soundPool.setOnLoadCompleteListener(new OnLoadCompleteListener() {
                @Override
                public void onLoadComplete(SoundPool soundPool, int sampleId, int status) {
                    // TODO Auto-generated method stub
                    soundPool.play(wav,100, 100, 0, 0, 1f);
                }
            });

        }        
    });

    streamThread.start();
}
