Stop a service at specific time

Question

I am starting my service using below code repeatedly. My service starts at 8am everyday. And AlarmManager repeates at every 1 min. I want to stop this sevice at 6pm. how can I do this ?

    AlarmManager manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    PendingIntent loggerIntent = PendingIntent.getBroadcast(this, 0,new Intent(this,AlarmReceiver.class), 0);

    Calendar timeOff9 = Calendar.getInstance();
    timeOff9.set(Calendar.HOUR_OF_DAY, 08);
    timeOff9.set(Calendar.MINUTE, 00);
    timeOff9.set(Calendar.SECOND, 00);
    //--------------------------------------------------------------------------------------------------------------------
    long duration = userinterval * 60 * 1000;
    manager.setRepeating(AlarmManager.RTC_WAKEUP,timeOff9.getTimeInMillis(), duration, loggerIntent);

In order to cancel at 6pm exactly, I would consider 2 options:

Each time the alarm triggers (i.e. every 1 minute), check the time, and cancel if time is after 6PM.
Set a once-off alarm in AlarmManager to go off at 6PM exactly. In that alarm, cancel.

I prefer option 2 for simplicity, and modularity of each code block. So for me, I would use (2) in my proof-of-concept code, while working on the solution.

But option 1 is better from a resources point of view, as the Android system only needs to remember a single alarm. I would use (1) in my final production code.

This way of working is just my personal preference, and most ppl probably will say to use (1) right away from the start.

The details about cancelling are below...

Below answer copied from How to cancel this repeating alarm?

Call cancel() on AlarmManager with an equivalent PendingIntent to the one you used with setRepeating():

Intent intent = new Intent(this, AlarmReceive.class);
PendingIntent sender = PendingIntent.getBroadcast(this,
               0, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

alarmManager.cancel(sender);

this code should be in my activity from where I am starting AlarmManagr. right?but how to cancel at 6pm exactly. — user2310041, May 10 '13 at 10:14
I have updated the answer to provide 2 common ways to know when to cancel. — Richard Le Mesurier, May 10 '13 at 12:35
I would have never thought of either of these two methods. Thank you! — gatlingxyz, Jul 16 '14 at 22:48
