Android Apidemos Sample resolution (m) App->alarm->alarm Service

The Alarm service and the Alarm Controller example are very similar, except that the Alarm service is used to schedule a service, and the previous example is to schedule a broadcast.

Previously said Pendingintent, can describe an activity, broadcast, or a service. This example schedule a alarm event to start a service. This is typically used to perform a more time-consuming task.

If writing a service will be followed by a special example to illustrate, only not in detail. As long as you know Alarmservice_service is a service on the line.

The following code is used to schedule a multiple alarm event to start Alarmservice_service

Private Pendingintent Malarmsender;     
 ...     
Create a intentsender that would launch our service, to be scheduled     
 //with the alarm manager.     
Malarmsender = Pendingintent.getservice (Alarmservice.this,     
 0, New Intent (Alarmservice.this, Alarmservice_ Service.class), 0);     
...     
We want the "alarm to go" seconds from now.     
Long firsttime = Systemclock.elapsedrealtime ();     
          
Schedule the alarm!     
Alarmmanager am = (alarmmanager) getsystemservice (alarm_service);     
Am.setrepeating (Alarmmanager.elapsed_realtime_wakeup,     
 firsttime, 30*1000, Malarmsender);

Cancel this alarm event:

and cancel the alarm.     
Alarmmanager am = (alarmmanager) getsystemservice (alarm_service);     
Am.cancel (Malarmsender);

Code is similar to Alaram controller, the same method can schedule a alarm event to trigger an activity.
