Try a few of these tutorials, they all use a progress bar within them.

In my application I have music player implemented as background service. In that service I send broadcast messages every 500ms where I provide info about current position. When player is paused I stop sending messages. And in every activity I register for listening to this messages so I am able to update visible player. For sending messages I use handler which runs on background thread.

private Runnable mUpdateProgressRunnable = new Runnable() {

        @Override
        public void run() {
            if (mMediaPlayer != null && !mSeeking) {
                int duration = mMediaPlayer.getDuration();
                int currentPosition = mMediaPlayer.getCurrentPosition();
                Bundle params = new Bundle();
                params.putInt(Broadcaster.P_PLAYER_DURATION, duration);
                params.putInt(Broadcaster.P_PLAYER_POSITION, currentPosition);
                getRferl().getBroadcaster().send(Broadcaster.E_PLAYER_CURRENT_POSITION, params);
                mUpdateProgressHandler.postDelayed(this, 500);
            }
        }
    };

Rferl is my application,Broadcaster is just wrapper for LocalBroadcastManager

thanks on answering my question but i am not implemented any service, i have used Handler to update the progress bar continously , how can i get this handler object on recreating the activity, thus i also need to store the MediaPlayer object ? – Aug 27 '12 at 11:12
This is why I implemented service which hold media player and every activity can listen to broadcast and updates status of progressbar. Sorry I can not help you, I did not implemented media player this way. I try to not hold shared objects in activities, so I have little experience have to recreate it correctly. I use application object or background services for this purpose. It is much easier for me :) – pcu Aug 27 '12 at 11:50
