Alarmmanager With Pending Intent

The code snippet below.... public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ///////////Do som

Solution 1:

//try this

AlarmManager am=(AlarmManager)getApplicationContext getSystemService(Context.ALARM_SERVICE);

PendingIntentpendingIntent= PendingIntent.getBroadcast(this, 0,  intent, PendingIntent.FLAG_CANCEL_CURRENT);

  am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(),(9 * 1000), pendingIntent);

Solution 2:

Never, ever use FLAG_CANCEL_CURRENT with PendingIntents that are set as alarms.

What happens is that you wind up canceling the validity of the PendingIntent currently held by the alarm manager, and this means that the alarm manager can no longer tell that any newly-set alarm matches that old PendingIntent. You wind up with the old (invalid) alarm still registered along with your new one. If you keep doing this you can wind up with hundreds (or more!) stale alarms registered in the system, none of which will actually do anything but which are taking up memory and CPU.
