Question

I need to run a service each night at midnight. I would like to use the AlarmManager to do this.

Can you give me some guidance of how to make it work correctly?

alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
alarmManager.setInexactRepeating(AlarmManager.ELAPSED_REALTIME, System.currentTimeMillis(), AlarmManager.INTERNAL_DAY, serviceIntent);

Perhaps I need to use a Calendar object to specify the time? Thanks for any help!

Answer 1

setInexactRepeating(), as the name suggests, is inexact. Bear in mind that it might run somewhat before or after midnight.

To determine when midnight is, use a Calendar object. Then call getDate() to get a Date and getTime() on the Date to get the proper millisecond value for your setInexactRepeating() call.
