Why isn't my alarm going off? (android)

Question

My alarm does not go off at the specific time or at all (I have tried setting it to one minute of current time). I have made sure that setAlarm() is going off because the log Log.d("asas", "adasd"); goes off. I do not know what is wrong, if you see how I can fix this please let me know. Thanks

public void setAlarm(){
    AlarmManager alarmMgr = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    Intent intent = new Intent(this, DrawOverAppsService.class);
    PendingIntent alarmIntent = PendingIntent.getActivity(MainActivity.this, 123, intent, 0);
    if(sp.getBoolean("startChecked",false) == true) {
        Log.d("asas", "adasd");
        java.util.Calendar calendar = java.util.Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        calendar.set(java.util.Calendar.HOUR_OF_DAY, 19);
        alarmMgr.setRepeating(AlarmManager.RTC,
                calendar.getTimeInMillis(),
                AlarmManager.INTERVAL_DAY, alarmIntent);
    }
    if(sp.getBoolean("startChecked",false) == false) {
        Log.d("asdasd","asdasdasd");
        alarmMgr.cancel(alarmIntent);
    }
}

Changed PendingIntent alarmIntent = PendingIntent.getActivity(MainActivity.this, 0, intent, 0); to PendingIntent alarmIntent = PendingIntent.getService(MainActivity.this, 0, intent, 0);
