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