Canceling alarms from AlarmManager

Question

I am working on application which is get the alarm time from database every 2 AM and then at the specified time the activity shows up, my app works fine, but when I manually change the data/time of the device, previous alarms are triggered and I should prevent to this to happens.

Here is my PendingIntent:

  Intent i = new Intent(mContext, AlarmReceiver.class);  
  PendingIntent pi = PendingIntent.getBroadcast(G.context, _id, i,
                 PendingIntent.FLAG_UPDATE_CURRENT);

Which each _id is unique and when I make a receiver for date changed event before my alarm cancel method fired previous alarms go off!

Can some body help to solve this problem?

Try this code:

Intent intent = new Intent(this, Mote.class); PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 1253, intent, 0); AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); alarmManager.cancel(pendingIntent);
