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 my Alarm
BroadcastReceiver, which in turn fires off my Service. However, I want
to set up so that it calls said Intent twice a day and to only
schedule the alarms if they haven't already been set (likewise for
canceling the alarms).
However, I am unsure if the following code is the correct way to set
and cancel alarms.
//Static function for setting the alarm
//My midday calendar object (cal1)
...
//My evening calendar object (cal2)
Intent myIntent = new Intent(context, MyAlarmReceiver.class);
PendingIntent firstCallIntent =
PendingIntent.getBroadcast(context, FIRST_CALL_ID, myIntent,
PendingIntent.FLAG_NO_CREATE);
PendingIntent secondCallIntent=
PendingIntent.getBroadcast(context, SECOND_CALL_ID, myIntent,
PendingIntent.FLAG_NO_CREATE);
if(firstCallIntent != null){
if(DEBUG){
Log.d(TAG, "Setting Midday Alarm");
}
firstCallIntent = PendingIntent.getBroadcast(context,
FIRST_CALL_ID, myIntent, 0);
alarms.setInexactRepeating(AlarmManager.RTC_WAKEUP,
cal1.getTimeInMillis(), AlarmManager.INTERVAL_DAY, firstCallIntent);
}
if(secondCallIntent != null){
if(DEBUG){
Log.d(TAG, "Setting Evening Alarm");
}
secondCallIntent = PendingIntent.getBroadcast(context,
SECOND_CALL_ID, myIntent, 0);
alarms.setInexactRepeating(AlarmManager.RTC_WAKEUP,
cal2.getTimeInMillis(), AlarmManager.INTERVAL_DAY, secondCallIntent);
}
//Static call to cancel the alarm.
Intent myIntent = new Intent(context, MyAlarmReceiver.class);
PendingIntent firstCallIntent =
PendingIntent.getBroadcast(context, FIRST_CALL_ID, myIntent, 0);
alarms.cancel(firstCallIntent);
firstCallIntent.cancel();
PendingIntent secondCallIntent =
PendingIntent.getBroadcast(context, SECOND_CALL_ID, myIntent, 0);
alarms.cancel(secondCallIntent);
secondCallIntent.cancel();
