[android-developers] Re: soundpool looping problem

FYI ... MediaPlayer looping isn't entirely 'stable'. See:

Sorry I don't have time to read your code. But in the past, I also had
issues, when I needed to loop soundpool sounds that were stopped()
before they needed to play again (in looped mode).

If you can't find a solution, I can think of two alternatives:
1. Implement manual looping: not too elegant and accurate, but 'guess'
when you playback has ended, and then start the same sound again
2. Use MediaPlayer, it is stable in looping
