Problem with BroadcastReceiver and IntentService

[Ozzy Boshi]

Hello JavaRanch Forum,
I am a begingger in Android Java Programming and I stumbled upon a problem.

I want, every time my phone boots up, a service that is activated every x minutes.
In order to do this I tried to use a BroadcastReceiver that creates a new AlarmManager object in this way.

public class myBroadcastReceiver extends BroadcastReceiver {
@Override
	public void onReceive(Context context, Intent callingIntent) {
		Intent intent = new Intent(context,UpdaterService.class);
		PendingIntent pendingIntent = PendingIntent.getService(context, -1 , intent, PendingIntent.FLAG_UPDATE_CURRENT);
		AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
		alarmManager.setInexactRepeating(AlarmManager.ELAPSED_REALTIME, System.currentTimeMillis(), AlarmManager.INTERVAL_FIFTEEN_MINUTES/15, pendingIntent);
		Log.d("myBroadcastReceiver","Receiver OK");
	}
}

I set up my android manifest file and all seems ok to me.
When the phone boots up i see the "Receiver OK" message on my Logcat window.
At this stage i'd expect that this broadcast receiver, every minute, is set to launch a new instance if UpdaterService.class but it doesn't happen.
Right now the UpdaterService class is a subclass of IntentService and it's made of only of a constructor and a onHandleIntent() method (overridden).
Inside the onHandleIntent there is only a Log.d() , so at the end i would expect to see this Log.d passing through my Logcat window but this does not happen, can someone tell me why?
If i try to launch UpdaterService from an Activity using startservice(), updaterservice fires up and the Logcat window show the messages (but only once of course)

Here you are UpdaterService.class even if there's nothing interesting...

public class UpdaterService extends IntentService {


	private final static String TAG ="updaterservice";
	public UpdaterService() {
		super(TAG);
		Log.d(TAG,"Object created");
		// TODO Auto-generated constructor stub
	}

	@Override
	protected void onHandleIntent(Intent arg0) {
		Log.d(TAG,"onHandleIntent launched");

	}

}
