Alarm Manager : How to Call Alarm Manager at particular time?

Question

I wanted to know How I can set Alarm for a particular time. For example I want to set alarm for morning 9am daily. I googled a lot but found only the way to set alarm for a given interval only. like after 2 hours or next day.

This should help: http://stackoverflow.com/questions/5938213/android-alarmmanager-rtc-wakeup-vs-elapsed-realtime-wakeup — stephendnicholas, May 08 '12 at 10:18

hope this code helps you

Calendar calendar = Calendar.getInstance();

//9 AM 
calendar.set(Calendar.HOUR_OF_DAY, 9);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);
AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
PendingIntent pi = PendingIntent.getService(context, 0, new Intent(context, YourClass.class), PendingIntent.FLAG_UPDATE_CURRENT);
am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pi);

you should create BroadcastReceiver to receive intent.

read the documentation for further details

The second parameter to setRepeating() on AlarmManager is when you want the alarm to go off first. Set that to be 9am tomorrow using a Calendar object, and use an RTC or RTC_WAKEUP alarm.
