Android alarmmanager cancel and start not working -

i have following code set alarm when main activity starts , cancel when logging out

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     ...      // schedule alarm     intent intent = new intent(this, myreceiver.class);     alarmintent = pendingintent.getbroadcast(this, 0, intent, pendingintent.flag_update_current);     alarmmanager = (alarmmanager) getsystemservice(context.alarm_service);     if (pendingintent.getbroadcast(this, 0, intent, pendingintent.flag_no_create) == null) {         alarmmanager.setinexactrepeating(alarmmanager.elapsed_realtime, 0, alarmmanager.interval_day, alarmintent);     } }  private void logout() {     if (alarmmanager != null) {         alarmintent.cancel();         alarmmanager.cancel(alarmintent);     }      intent = new intent(mainactivity.this, loginactivity.class);     i.addflags(intent.flag_activity_clear_task);     startactivity(i);      finish(); } 

but when log out, log in, , enter main activity code alarmmanager.setinexactrepeating() never reached.

that line never reached, because pendingintent checking exist, because creating pendingintent 2 lines earlier. since pendingintent exists, flag_no_create call still return it, , not equal null.
