    }

    @Override
    public void onBackPressed() {
        mMediaPlayer.release();
        finish();
    }
}

Can you pls help me to figure it out.

If you provide a working code with mediaplayer basic controls like play ,pause and update seekbar , It will be a great help for those who like to work with your Player View.

just use the setMax() function to set some initial non zero default value of the track
