Question: This sound so simple that I can't figure out why I can't find the answer lol 

I have a working sound pool class (thanks to a tutorial and some tweaking I did), and it works fine. 

the problem now is that I want to be able to change my background music randomly. (not always have the same music in a loop but have 2 or 3 and when one finishes I play one of the 2 others).

problem is I can't find a way to get notified that the music has finished playing.

Any ideas ?

Answer: 
It can't be done with SoundPool as far as I can tell.

The only audio 'player' that I know which can provide a completion notification is 
[MediaPlayer](http://developer.android.com/reference/android/media/MediaPlayer.html) - it's more of a complex beast than SoundPool but allows setting an OnCompletionListener to be notified when playback is complete.
This is what I do: 

On **startup** I get the length of each sound-click using a MediaPlayer:

```
private long getSoundDuration(int rawId){
   MediaPlayer player = MediaPlayer.create(context, rawId);
   int duration = player.getDuration();
   return duration;
}

```

and store the sound plus the duration together (in a DTO-type object).
