Flight Feeder Android Not Working?

Hey Guys,
I thought it would be cool to do the FlightFeeder for Android project. So I bought everything required and then completed all the steps. Yet for some reason I am getting nothing on my Nexus 5 (on the FlightFeeder app). I was wondering if there were any trouble shooting tips? I’m really starting to get frustrated now :angry:

What antenna are you using and where is it located? Also, is GPS enabled on your device? It’s required to help determine the aircraft positions.
