Edit: How to trigger a broadcast via the AlarmManager:

IntentbroadCastIntent=newIntent(this, "YOURBROADCASTRECEIVER.class");
PendingIntentintent=PendingIntentpendingIntent= PendingIntent.getBroadcast(
                this, 0, intent, 0);
AlarmManageralarmManager= (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                System.currentTimeMillis(),
                AlarmManager.INTERVAL_HOUR, pendingIntent);

Note that this alarm will set off immediately the first time. If you want to set it of later you can multiply "System.currentTimeMillis() * x" where x = 1000 would mean one second.
