Just setLooping(true) on the MediaPlayer instead of playing it again onCompletion.

http://developer.android.com/reference/android/media/MediaPlayer.html#setLooping(boolean)

Sets the player to be looping or non-looping.

With looping on it'll repeat indefinitely by itself without breaks, you don't have to worry about handling it yourself.

yourStereo = MediaPlayer.create(this, R.raw.pl);
yourStereo.setLooping(true);
yourStereo.start();

You sure there is no delay in your file? Like silence at the start or end of it? – Ken Wolf Jun 25 '13 at 09:04
You can try using a handler to set seek to beginning x milliseconds before the end of file: http://stackoverflow.com/a/10423155/833647 – Ken Wolf Jun 25 '13 at 09:14

There's indeed issue with setLooping: small delay between end and start. Which is probably due to reloading of file or MediaPlayer seeking to start https://code.google.com/p/android/issues/detail?id=18756 – GregoryK Nov 05 '15 at 07:57

Use SoundPool for low-latency media playback, instead of MediaPlayer.

checj this http://www.edumobile.org/android/android-programming-tutorials/sound-pool-example-in-android-development/ – blganesh101 Jun 25 '13 at 09:05
SoundPool is not the solution for longer audio loops approx > 3 seconds – SARose Jan 13 '15 at 20:14

I found other solution:

afd = assetManager.openFd(nameSound);

player.setDataSource(afd.getFileDescriptor(),
                     afd.getStartOffset(), afd.getLength() - 1000);
afd.close();
player.prepare();
player.setLooping(true);
player.start();

You only need to define the duration 1000(0.1ms) less instead that the total duration.
