@IlyaGazman For info on pull requests, see this (or any other) general info tutorial and this libGDX specific page for contributors. You don’t have to get it right the first time - that is what code review is for, so don’t worry about it too much.

@shatterblast: By warning, I meant this line:
WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5., which has nothing to do with any networking and everything to do with windows registry.

The standard way includes using an InputStream with some REST protocols. The Google HTTP Client can help some. You might check StackOverflow for some references.
