I'm writing an Android app that uses the Apple MusicKit SDK for Android. I am trying to understand how to handle the Apple Music user token, once I got it from authentication flow. I don't know when the token will expire, it is not a regular jwt token, so I cannot check the expiration date. And I don't want to run the auth flow on every app run, it will be annoying for the users. Any guidance on how to handle and invalidate apple music user tokens?

I have downloaded the official Apple MusicKit SDK for Android and integrated 2 AARs it has in my app (musickitauth-release-1.1.2.aar and mediaplayback-release-1.1.1.aar). When I try to build my app I'm getting an error:
Manifest merger failed : android:exported needs to be explicitly specified for element <activity#com.apple.android.sdk.authentication.SDKUriHandlerActivity>. Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined. See https://developer.android.com/guide/topics/manifest/activity-element#exported for details.
Which makes sense, since when I look into the AAR's AndroidManifest.xml I see that this is missing in SDKUriHandlerActivity. Can this be fixed?

I have an app which plays songs from Apple Music using MPMusicPlayerController.applicationQueuePlayer. I am constantly connecting to my backend and updating the song queue using player.prepend(MPMusicPlayerStoreQueueDescriptor(storeIDs: ids)).In order to test the app, I left it running overnight in background. In the morning the music was not playing, the lock screen doesn't show any music controls and my app was not running - seems like when the music was stopped ios killed my app since it doesn't do anything in the background. When I go back to my app the playback is totally broken, when I try to play the next track or start playback again - nothing works, I need to kill the app and start over again.I did this test several times and every time after about 1.5 hours the app stops playing after it plays exactly 30 songs. Interestingly, I'm always prepending 30 songs using player.prepend(), however, debugging showed that the song queue is actually bigger, like 105 songs or so. When I'm looking at the logs then I see all possible error logs and warnings from music player during those 1.5 hours, but the music plays fine during that time. The one interesting log is TIMEOUT at the end, even though during this 1.5 hours I get similar message 4 times, however the last one ends my app.I got no hopes with the official Feedback Assistant since they totally ignore for months everything I write there, not even writing back "we got it, we are looking into it", so I'm trying my luck here and in SO.Here are the logs with timestamps, filtered to leave only meda player related logs (full logs here)2019-11-30 04:04:36.175688+0100 MyApp[4278:1630772] [Middleware] TIMEOUT Request: <MPCPlayerRequest: 0x280d0a520 label=MPMusicPlayerController-applicationMusicPlayer playerPath=<MPCPlayerPath: route=<MPAVEndpointRoute: 0x280a0a940 name=iPhone uid=LOCAL> bundleID=com.apple.MediaPlayer.RemotePlayerService pid=4281 playerID=MPMusicPlayerApplicationController>> timing out.

Sometimes the MPMusicPlayerController is not playing the music when I start my app. I'm getting following errors (or very similar):[SDKPlayback] -[MPMusicPlayerController prepareToPlay] completed error: Error Domain=MPCPlayerRequestErrorDomain Code=1 "No commands provided."

There are so many points where it seems not to be possible to access data using Apple Music API. For example, there is a "get activity" request, however I need an ID of an Activity. What should I do to get one of those, from which request do I get them? I would like to show a list of catalog Activities or maybe just "TOP" activities/moods/etc from the beginning, not depending on anything else. The same thing applies to other data, like Apple Curators, and so on.There is already a question regarding the same issue, but it is quite old and no one answered it yet - https://forums.developer.apple.com/thread/90911Are there any parameters that I'm missing or is it just not possible with this API? That would make also endpoints like "get activity" useless...
