Android : How to restart Media player service from where it was paused?

I read docs at Android Developer and still cant pause my service and then start it from the paused state (Playing the song).

With my current code, it always restart from the beginning of the song, but I would like to restart where the song was paused (with the stopClick)

The Service class:

public class BackgroundSoundService extends Service {
    MediaPlayer player;

    public IBinder onBind(Intent arg0) {

        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        final int MAX_VOLUME = 100;
        player = MediaPlayer.create(this, R.raw.lightmusic);
        player.setLooping(true);
        float soundVolume = 77;
        final float volume = (float) (1 - (Math.log(MAX_VOLUME - soundVolume) / Math
                .log(MAX_VOLUME)));
        player.setVolume(volume, volume);

    }

    public int onStartCommand(Intent intent, int flags, int startId) {
        player.start();
        return 1;
    }

    public void onStart(Intent intent, int startId) {

    }

    public IBinder onUnBind(Intent arg0) {
        // TO DO Auto-generated method
        return null;
    }

    public void onStop() {
         player.pause(); 
    }

    public void onPause() {
        player.pause();
    }

    @Override
    public void onDestroy() {
        player.stop();
        player.release();
    }

    @Override
    public void onLowMemory() {

    }
}

And my Activity with 2 onClick methods:

public class MainActivity extends QuizActivity {   
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.menu);

            startService(new Intent(this, BackgroundSoundService.class));
        }

        public void stopClick(View v) {
            stopService(new Intent(this, BackgroundSoundService.class));
        }

        public void playClick(View v) {
            startService(new Intent(this, BackgroundSoundService.class));
        }

        @Override
        protected void onResume() {
            super.onResume();
        }
    }
