I have a Main activity that calls a StartServiceAt. That service, if it detects that Main is paused, runs StartActivity(Main).
However, if the service is in the background, Main never gets started. I have new Android 10 mobile. It worked fine on old Android 9 mobile.
I've seen several posts on the problems with Android 10 and background services, how my app service needs to be foreground to start any other activity, and I have read the 'services lifecycle on android 8+', but still no go.
For testing, I create a timer then hit the Home button on my mobile so the app goes into background
This successfully triggers ReminderService at the appointed time.
This runs successfully, finds Main is paused, tries to wake the phone (not relevant to this issue), then should start Main.
From what I have read, by default the service will be Service.AUTOMATIC_FOREGROUND_WHEN_NEEDED so it should have become foreground, and so it should have been able to start Main. I tried forcing it Service.AUTOMATIC_FOREGROUND_ALWAYS but no change.
