how to play sound looping without gap in android

I want to play a "wav" file of 1 seconds multiple times without gap. All my attemps failed. My existing code is as follows;

MediaPlayer mMediaPlayer = MediaPlayer.create(this, R.raw.my5s);
MediaPlayer mMediaPlayer2 = MediaPlayer.create(this, R.raw.my5s);
mMediaPlayer.setVolume(1, 1);
mMediaPlayer.setLooping(true);
this.mMediaPlayer.setNextMediaPlayer(mMediaPlayer2);

this.mMediaPlayer.start();

I also tried the solutions in the following links;

1. play .ogg file


2. manual looping
