29 * This service exists primarily to allow the stopwatch notification to alter the state of the
30 * stopwatch without disturbing the notification shade. If an activity were used instead (even one
31 * that is not displayed) the notification manager implicitly closes the notification shade which
32 * clashes with the use case of starting/pausing/lapping/resetting the stopwatch without
33 * interruption.
