alarm and notification not triggered at specified time

Question

I am trying to trigger a notification and an alarm at a specified time. I have put log information to console to see if the correct time is being set and it is fine. However

Answer 1

Inside btn_add_task listener, set the alarm as below -

Intent notifyMessage = new Intent(getApplicationContext(),NotificationMessage.class);
PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), 0, notifyMessage, PendingIntent.FLAG_UPDATE_CURRENT);    
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.setRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY,pi);

Now, put a log inside onReceive of NotificationMessage class to be sure that the alarm is fired on time. Hope, now your program will run.
