That's the thing, if I set a shared preference flag or cached flag via cache object, and they did try to check for that value in onResume, wouldn't the first activity from the back stack to get the foreground check its state, then set it back to false after checking for it being true before having to do work? Even if I didn't reset the flag, every time it would hit that function, it would still get caught in that flag, so that isn't really useful. So there is no way that I can just broadcast one intent that my listening activities can listen to after the intent is sent as soon as they get the foreground again?
