Answer 1

You could use simple if-check to handle the pausing. Try this:

MediaPlayer mp = MediaPlayer.create(this, Uri.parse(Environment.getExternalStorageDirectory().getPath()+ "/Music/jaihind.mp3"));
if(mp.isPlaying()) {
    mp.pause();
} else {
    mp.start();
}

Note:

mp = MediaPlayer.create(...);

is already preparing the MediaPlayer returned, so you cannot call prepare (or its variants) again (and there is no need for onPreparedListener as well).

Answer 2

I think you have to use this

 public class Sound extends Activity{

MediaPlayer mp;

    @Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    mp.release();
}

}
