mmmm normally,you create a new profile dedicated for the Google Services and in there install all dependent applications (and not inaide a private space) which could be locked when you switch the profile therefore not running and implicit,no notifications.
But, i could be wrong...
Im having troubles finding "easy" in which profile i am after not using the phone for a period of time.
AND...still cand block terminating the session frrom the lock scrren even without unlocking the session...arghh
