MediaPlayer plays music files in debug mode only (Android)

Question

I wrote an Android application (in eclipse) that plays a music file as follows:

MediaPlayer mediaPlayer = new MediaPlayer(); try { mediaPlayer.setDataSource(fileName); mediaPlayer.prepare(); mediaPlayer.start(); // mediaPlayer.stop(); } catch (Exception e) { Log.d("Exception---", e.getMessage()); } 

When I run it, it does not play the file (and does not show any exception), but when I switch to "debug mode" and trace it line by line, it plays the file. I'm really confused. Could you help me find out what happened?

Thanks.

Put the log in front of "mediaPlayer.setDataSource (file_name)" and check if you get a valid file name in release mode.
