Android Alarmmanager - Scheduling A Recurring Intent To Fire Off Twice A Day

After reading lots of sample code into this matter, I'm trying to figure out the simplest way to achieve the following: I want to be able to schedule an Intent that calls back to m

Solution 1:

That seems alright to me, however instead of creating two calendar objects you could just set your interval to

AlarmManager.INTERVAL_DAY/2

unless your intents are doing different things.

Also,

alarms.cancel(firstCallIntent);
alarms.cancel(secondCallIntent);

should be enough to cancel all alarms of those types, no need for:

firstCallIntent.cancel();

Edit: Setting 2 calendar objects

//midday
Calendar cal1 = Calendar.getInstance();
cal1.set(Calendar.HOUR_OF_DAY, 12);
cal1.set(Calendar.MINUTE, 00);
cal1.set(Calendar.SECOND, 00);

//7pm
Calendar cal2 = Calendar.getInstance();
cal2.set(Calendar.HOUR_OF_DAY, 19);
cal2.set(Calendar.MINUTE, 00);
cal2.set(Calendar.SECOND, 00);

Calendar.getInstance() will return a calendar object and set it to the current system time. Each .set method changes a certain variable of that calendar object. So currently if it was 8pm, it would set the alarm for 12 and 7 that day, which would be no use. So if you want to set it for the next day, you'll need to use cal1.add(Calendar.DAY_OF_MONTH, 01); to add an extra day, setting for that time the next day. Hope this helps.
