AlarmManger不起作用

Question

当我使用日历时，它不起作用！

    Calendar cal = Calendar.getInstance();
    cal.set(2016, 11 , 28);
    Intent intent = new Intent(this, MyBroadcastReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(
            this.getApplicationContext(), 54, intent, 0);
    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    alarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis() , pendingIntent);
