title: Android Geofencing sample app only works if another app is open using GPS
body: <p>I am working with the <a href="http://developer.android.com/training/location/geofencing.html">Geofence API Sample application</a> I've got it running and seems to work alright. I did make the modifications to it to use BroadcastReceiver instead of the IntentService.</p>
  
  <p>But I will only get the notifications if I have some other app open that is using GPS such as Maps, or GPS Tester app.</p>
  
  <p>If I don't have one of those apps open and I walk into the geofence zone nothing happens. But as soon as I launch one of them I will get the notification within a few seconds.</p>
