Android Auto Grid Layout with Media3

Got it working!

It apears you can't style songs directly under your library root, i.e.

Root
  |-Song
  |-Song
  |-Song

They need to be under a container media item (i.e. an Album, artis, playlist, madeup container type)

Root
  |-Playlist
    |-Song
    |-Song

Thanks again for the help

Thanks for reporting!

This works for me with the session demo:

  @OptIn(UnstableApi::class)
  override fun onGetLibraryRoot(
    session: MediaLibraryService.MediaLibrarySession,
    browser: MediaSession.ControllerInfo,
    params: MediaLibraryService.LibraryParams?,
  ): ListenableFuture<LibraryResult<MediaItem>> {
    val rootExtras =
      Bundle().apply {
        putInt(
          MediaConstants.EXTRAS_KEY_CONTENT_STYLE_BROWSABLE,
          MediaConstants.EXTRAS_VALUE_CONTENT_STYLE_CATEGORY_GRID_ITEM,
        )
        putInt(
          MediaConstants.EXTRAS_KEY_CONTENT_STYLE_PLAYABLE,
          MediaConstants.EXTRAS_VALUE_CONTENT_STYLE_CATEGORY_GRID_ITEM,
        )
      }
    return Futures.immediateFuture(
      LibraryResult.ofItem(
        MediaItemTree.getRootItem(),
        MediaLibraryService.LibraryParams.Builder().setExtras(rootExtras).build(),
      )
    )
  }

The only difference to your code I see is that the library params are created newly with MediaLibraryService.LibraryParams.Builder().setExtras(rootExtras).build(), but I don't think this should make a difference.

The same works with the media3 branch of UAMP that isn't using the same constants but the values that are used are the same.

Hey @marcbaechinger, thanks for the quick reply. I've confirmed that your example does what I'm after so now I have the fun task of working out whats different between my project and the example.

I'll drop another comment and close this off once I work out whats different.

Glad it's working and thanks for the update why it wasn't!
