Android MediaController Play / Pause and Seekbar button not updating

Question

I am using MediaController.MediaPlayerControl to display the MediaController at the bottom of my custom view, but I cannot get it to work correctly. When I play music for the first time, then there should be a pause button, but there is playback instead, and when I press this button, the music pauses correctly and the state remains unchanged and after that it works correctly. Also, when I play the next song, the old MediaController widget overlaps the new one. And sometimes the progress / search indicator is not updated during music playback. It just updates when something is clicked on the MediaController (Play / Pause, forward, etc.).

I found these questions to be similar to mine, but I don’t think the answers they received solve my problem.

• Android mediacontroller play Pause not updating properly
• Android MediaController does not update
• Android VideoView Show Controls "Play" Initially instead of "Pause" Even if the file is already playing

This is how I initialize the controller:

private void setController()
{
    controller = new MusicController(this);

    controller.setPrevNextListeners(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
            playNext();
          }
        }, new View.OnClickListener() {
          @Override
          public void onClick(View v) {
            playPrev();
          }
        });

    controller.setMediaPlayer(this);
    controller.setAnchorView(findViewById(R.id.song_list));
    controller.setEnabled(true);
}

This is how I show the controller:

public void playMusic()
{
        musicSrv.playSong(); //Play song in a service
        setController();
        controller.show(0);
        controller.requestFocus();
}

I had exactly this problem. I don’t know if you need help, but I thought I would send it anyway. For posterity, do you follow this tutorial ?
