-- Edit --
I would love to have more space in posts too. Is there some kind of trick to get more space?!
The site looks like this |.........|content|...........| (. = empty space/background)

I am having a problem accessing my API, JSON. When I put in the URL I have issues connecting, On the emulator and device I get "Check you Internet connection"...it is an external URL.

I've allowed internet in the manifest.

I've been told to use the IP address but that doesn't sound like a good fix to the problem.

Any thoughts?
