ahhh
OK
I haven't look at the code much (and don't need to), but first thing
you should do is to think it out. What do you need to create app for?
Currently you have crated app for non existing website so it actually don't do anything.
I can suggest that you find some working service over the net, or create your own, and than make appropriate application for it.
Since it's client-server relationship, you first need to find/create server and than client. Now you have client without server.
Maybe you could also create some
test app that will support your current app but that depends on your skill
You should decide what will need less work. Crate server or to re-factor app.
