Starting DownloadService at 5AM in the background every day

Hi, we use media3 library to display video and play audio in our application to take a user through a workout routine step by step. We would like to give the user an option to predownload some of this media every morning (while their phone is charging and they have a network), so that the media is available regardless of their internet connection later in the day.

I have tried the following:

• Create a CoroutineWorker that gets waken up every morning at 5AM by the alarm manager.
• In the worker, use setForegroundAsync(foregroundInfo), and then call DownloadService.sendAddDownload with the DownloadRequest for all media files.

However, that doesn't work, since API > 31 doesn't allow starting services from the background, since ForegroundServiceStartNotAllowedException gets thrown.

I have also tried the following:

• Create a CoroutineWorker that gets waken up every morning at 5AM by the alarm manager.
• In the worker, use setForegroundAsync(foregroundInfo), and then call DownloadManager.addDownload directly to schedule the download.
  However, this doesn't seem to work correctly either, and there every once in a while there is an ANR that is recorded in the FirebaseCrashlytics that originates from the worker, so I'm not convinced that that is a right approach either.

Any ideas how to approach this? Everything that I have found originates from user pressing the button in the app, but what are recommendations if we want to offer the user the ability to pre-cache all of their media for a smoother offline experience. Thank you !
