I know this is old but recently had this issue with older devices,
particularly a Samsung Galaxy S running 2.2.
What you said about the 300ms seems to be correct, and the issue is because
you release the media player in the onCompletion(...) listener, a work
around would be to delay the release of the MediaPlayer using a Handler,
this is the solution I used:
mPlayer.setOnCompletionListener(new
MediaPlayer.OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mediaplayer) {
mHandler.sendEmptyMessageDelayed(MSG_MP_RELEASE, 1000);
}
});
private Handler mHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
if(msg.what == MSG_MP_RELEASE) {
mPlayer.release();
}
}
};
Also on older devices you need to make sure you keep a field reference to
the MediaPlayer because it can be released when it goes out-of-scope and an
over eager GC will release the MediaPlayer unexpectedly.
