- If DownloadService is configured to run as a foreground service,
it will remain started and in the foreground when downloads are
waiting for requirements to be met, with a suitable "waiting for
XYZ" message in the notification. This is necessary because new
foreground service restrictions in Android 12 prevent to service
from being restarted from the background.
- Cases where requirements are not supported by the Scheduler will
be handled in the same way, even on earlier versions of Android.
So will cases where a Scheduler is not provided.
- The Scheduler will still be used on earlier versions of Android
where possible.
Note: We could technically continue to use the old behavior on
Android 12 in cases where the containing application still has a
targetSdkVersion corresponding to Android 11 or earlier. However,
in practice, there seems to be little value in doing this.
