Cordova POST data with AngularJS - angularjs

Question

I was trying to POST my login credentials for one of my app built with Cordova and AngularJS. When I login from my browser, it works fine but when test the same in Android (also tested in iOS too, fails on both), the login fails and I get the following headers while debugging.
I saw the differences in these two headers, as in emulator the origin is
Origin: file://. It also has a warning sign for emulator saying "Provisional headers are shown"
Why is it failing in emulator and devices but works fine in browsers? Does cordova does anything internally while wrapping up the POST call?
I really don't understand why is it happening in emulators/devices but works fine in browsers.
In Browser - works fine
