How to get seekable progressbar in your notification that updates your mediaplayer instance in android q programatically?

Android Q and above provides functionality to include seek-able progress bar in our notification. I am creating a app that plays audio files from external storage.

MediaPlayer control progressbar

I want to implement the progress bar as shown in the image.

The problem is that i have implemented a progress bar and it is seekable but its doesnot update the mediaplayer when user seeks to a particular position on seekbar .

My implementation of progressbar

The code

Following code sets the metadata

mediaSession.setMetadata(MediaMetadataCompat.fromMediaMetadata(new MediaMetadata.Builder().putString(MediaMetadata.METADATA_KEY_TITLE, title) .putLong(MediaMetadata.METADATA_KEY_DURATION, Long.parseLong(listSongs.get(position).getmDuration())).build()));

Following code checks if mediaplayer is playing or not and sets the PlaybackState

 if(mediaPlayer!=null) {


                if(!mediaPlayer.isPlaying()){
                     playbackState = PlaybackState.STATE_PLAYING;
                }
                else{
                   playbackState =  PlaybackState.STATE_PAUSED;
                }

         mBuilder =  new PlaybackState.Builder()
                .setState(playbackState
                        , musicService.getCurrentPosition()
                        , 1
                )
                .setActions(PlaybackState.ACTION_SEEK_TO| 
                        PlaybackState.ACTION_PAUSE |
                        PlaybackState.ACTION_SKIP_TO_NEXT |
                        PlaybackState.ACTION_SKIP_TO_PREVIOUS |
                        PlaybackState.ACTION_PLAY_PAUSE)
                 ;




        mediaSession.setPlaybackState(PlaybackStateCompat.fromPlaybackState(mBuilder.build()));
        mediaSession.setActive(true);
