Android client and java server.

I need a skeleton Android client and corresponding Java server to be made. An app like this is what I need, but mine implements a server app before the PBX to handle the logic code. [login to view URL] I do not need it to be fully created, just a good skeleton with some connections made that I can build upon with some GUI elements. The Android client should have a basic gui set up with some buttons that send corresponding requests to the server app. This server should then respond with dummy data that I can change. The serer should also be able to reqest data from an Asterisk MySQL database that will be installed on a Linux distribution on another machine (Over LAN). This can be done using JDBC. What I really require is the base skeleton code to be created that I can easily build upon. The Android client/server should be able to communicate over the internet (Assuming no firewalls etc). The client and server should use simple code really, sockets and jdbc should be used and well commented.
