I use below code to play audio in background:
String[] Path = new String[] {path1, path2, ...};
mMediaPlayer.setDataSource(Path[i]);
mMediaPlayer.prepare();
You should override onCompletionListener like this,
mMediaPlayer.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
Log.i("Completion Listener","Song Complete");
mp.stop();
mp.reset();
mp.setDataSource([nextElement]);
mp.prepare();
mp.start();
}
});
If you use a onPreparedListener in your MediaPlayer then you cal also use the prepareAsync command and ignore the .start().
