回答1:

From the error, it looks like the previous instance of the MediaPlayer is not released completely. When the playback has completed, the player is in Paused state when the onCompletionListener is invoked. Can you please stop the MediaPlayer before releasing the same?

mMediaPlayer.stop();
mMediaPlayer.release();
mMediaPlayer = NULL;
mMediaPlayer = new MediaPlayer();
