31  * stopwatch without disturbing the notification shade. If an activity were used instead (even one
32  * that is not displayed) the notification manager implicitly closes the notification shade which
33  * clashes with the use case of starting/pausing/lapping/resetting the stopwatch without
34  * disturbing the notification shade.
