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.
I have more than 100 short sound clips and SoundPool is my best option. I want to play one clip just after another clip is finished playing. Upon finding that there is no onCompletionListener() equivalent I chose to implement a runnable. This works for me because the first sound is between 1 and 2 seconds long so I have the duration of the runnable set at 2000. Hope they work on this class because its got lots of potential!
