Issue with testing on Android

When I run the app in the browser I can get the data from the external server, all works fine. But when I test it on the android phone (Using Nexus 5) I don’t get receive any data. I just see a blank page with with a navigation bar. That is it.
To get the data I am just using $http.get method.

What is the problem and how to fix it? Anyone had this problem?
