Android: Empty playback notification using just_audio_background

[fedpinx]

Which API doesn't behave as documented, and how does it misbehave? Whatever I put in the MediaItem object inside the tag attribute of the AudioSource.uri, is not being taken into account when using just_audio_background and the Android OS audio notification. Looks like the data that is shown in the notification is taken from the metadata of the Uri, so if this is the case, what is the purpose of the MediaItem?

Minimal reproduction project Provide a link here using one of two options:

1. Using "The Example", replace one of the AudioSource.uri items with "http://icecast.radiofrance.fr/franceinfo-midfi.mp3" (France radio station)

To Reproduce (i.e. user steps, not code) Steps to reproduce the behavior:

1. Replace one of the AudioSource.uri items with "http://icecast.radiofrance.fr/franceinfo-midfi.mp3" (France radio station)
2. Play the audio
3. Send the application to background and check the OS system notification for playback, is completely empty.

Error messages

No visible error messages.

Expected behavior I would expect that it takes the MediaItem information to show in the notification as well.

Additional context In case this is the expected behavior for some reason, how can I change the data shown in the system notification?

Thank you for all your effort.

I'm closing this since the issue is I'm passing objects as extras and it only accepts integers and strings, would be great to clarify this in the docs! Thanks again and sorry for publishing this.
