AVRCP enabled music player application: Enable Browsing

Hello,

I apologize if I will sound too dumb, but I am desperate because I can't the solution for my problem.

I am developing a music player application which will respond to Play/Pause/Stop/Next/Previous media button keys if the device running the application is connected to a media player device, like a media player in the car.

Libraries I am using:

    bluez version: 5.19
    Dbus binding: GIO 2.42.1

For this I have implemented all the interfaces following the MPRIS D-Bus Interface Specification, and called the org.bluez.Media1.RegisterPlayer method.
The application is getting Play/Pause/Stop/Next/Previous key press events and is responding to them accordingly.

The next step is to implement the Browsing feature in the application. This is where I got stuck. I have implemented the org.mpris.MediaPlayer2.Playlists an the org.mpris.MediaPlayer2.TrackList interfaces, but if I press the Browse button on the media player device, isn't showing the dummy playlists and tracklists of the application.

I would really appreciate If somebody could help me and give me a good step-by-step description of what to implement, register or call in order to make it work.

If I wasn't detailed enough and I have to give more information, please tell me.

Actually browsing isn't implemented for TG only for CT, so while you might be doing everything correctly the implementation will never pickup the Playlists and TrackList objects, although the idea would be to do exactly that with playlists emulation the VFS and the TrackList the NowPlaying but it has not being done yet.
