I have read most posts re this issue, but still can't get my implementation working, can you please help?
Basically I want to initiate a BroadcastReceiver from within an Activity, to do something every 10 seconds. So I set the Alarm, but the code never actually reaches "onReceive()"... I can't spot any difference in my code from other examples, could you please take a look?
Also just to mention that I haven't put a receiver in the manifest file, as I understand that it is not needed since I register it within the activity.
Thank you!

You registered your receiver, but forgot to send the action to the receiver:
Intent intent = new Intent(ALARM_SERVICE);
sendBroadcast(intent);
