Dianne,
I have used both AlarmManager.ELAPSED_REALTIME_WAKEUP and
AlarmManager.RTC_WAKEUP.
I am currently setting a repeating alarm "attached" to a pending
intent in the GUI portion of the application. The pending intent
starts the service.
objPendingIntent = PendingIntent.getService(bServiceGUI.this, 0, new
Intent(bServiceGUI.this, bService.class), 0);
// Schedule the alarm!
long firstTime = SystemClock.elapsedRealtime();
AlarmManager objAlarmManager = (AlarmManager)getSystemService
(ALARM_SERVICE);
objAlarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
firstTime, 5*60*1000, objPendingIntent);
in the service
@Override
public void onCreate()
{
super.onCreate();
Thread objThread = new Thread(null, doTasks, "bService");
objThread.start();
}
private Runnable doTasks = new Runnable()
{
public void run()
{
PowerManager objPowerManager = null;
PowerManager.WakeLock objWakeLock = null;
try
{
objPowerManager = (PowerManager) getSystemService
(Context.POWER_SERVICE);
//objWakeLock = objPowerManager.newWakeLock
(PowerManager.FULL_WAKE_LOCK, "bService_Class");
objWakeLock = objPowerManager.newWakeLock
(PowerManager.PARTIAL_WAKE_LOCK, "bService_Class");
objWakeLock.acquire();
//Your processing tasks here.
}
catch (Exception e)
{
}
finally
{
try
{
objWakeLock.release();
}
catch (Exception e1)
{
}
}
bService.this.stopSelf();
}
};
