setProgress(int) method not working.

[ShabbirK52]

I am using setProgress(int) method with MediaPlayer. I am trying to update the seek_bar according to the progress of the MediaPlayer but it isn't working and the song lags everytime the Runnable is called.

Runnable runnable = new Runnable() { @Override public void run() { if (mediaPlayer.isPlaying()) { Seek_bar.setProgress(mediaPlayer.getCurrentPosition()); handler.postDelayed(this, 500); } } };
