Interface AlarmListener
public interface AlarmListener
This interface is implemented by a Java object that will receive alarm
notifications. An object implementing this interface can be supplied
to the AlarmManager.create method and used as the target for an alarm. When
the alarm fires then the fired method is called and the alarm firing is provided
as a parameter. By providing the alarm as a parameter, the same object
instance could be used for multiple alarms.

fired
void fired(Alarm alarm)
- This method is called when an alarm fires. If the alarm is a one shot
event or is the last alarm in a periodic alarm then the alarm should
be cancelled. Cancelling the alarm allows it to be reused thus
saving memory and increasing performance. If the alarm is a repeating
alarm then the Alarm.reset method should be called to schedule the
alarm to fire again later. This again improves performance through
memory optimizations.
- Parameters:
alarm
- This is the alarm that actually fired. The context of the
alarm can be retrieved using the Alarm.getContext method.
