Digging in:

• There's a new library in unbundled called car-media-extensions. It does not have the local maven publishing configuration that I added to the other libraries that we need, so it's not currently accessible. This will likely require a change to Unbundled that won't be available until the next release.
• android.car.media.CarMediaManager is no longer accessible. It looks like it can be found in android.car-system-stubs, if I add a compileOnly(files( link to it in media-lib's dependencies it can be found again. I believe this is because car-media-common used to compile in the car-system-stubs as an implementation dependency, but now only uses the stubs as a compileOnly dependency. This can be fixed fairly easily.
• com.android.car.media.common.source.MediaBrowserConnector.ConnectionStatus now seems to have a NONEXISTANT member. Likely an easy fix.
• com.android.car.media.common.source.MediaSourcesProvider seems to be gone. I can find it in the 20231102 release of unbundled but not in the current one.
• com. android. car. media. common. browse. MediaItemsRepository has a new options argument that needs to be handled.

@yiqunw700 The new car-media-extensions library will need some Gradle configuration applied to it. The change will be made in car-apps-dev. I'll make and submit that change, and then we'll have to wait for that change to be included in a release of ub-automotive-master. So your fixes won't work until that release is made.

So what you should do is to get things working against car-apps-dev. Once you get it working there you can upload the PR here. The presubmits will fail and that's fine, we'll just let it sit until the fixes in car-apps-dev land in ub-automotive-master and merge it then.

I'll link the change for car-apps-dev once I have it ready (today or tomorrow).

@yiqunw700 ag/27085619 has been created which adds the missing publishing configuration for car-media-extensions and a new library that seems to have been added since the last public release.

I have uploaded a branch named wb/froeht/fix-mediacompose which fixes the issue with android.car.media.CarMediaManager that I described in my second comment

You should be able to use those changes to work on fixing the other three issues. I would suggest copying the change in wb/froeht/fix-mediacompose into your own branch.

1051 should have fixed this. I might forget to close it.
