I'm working on an application that will run on a phone where the phone will be a station on a private Wi-Fi network. The phone will be a station, not an access point, and the private Wi-Fi network does not route to the Internet. My application needs to communicate with servers on the Internet as well as devices on the local Wi-Fi network, so it needs to have connections on both networks at the same time. I've been trying to figure out how to do this.

I am working on the android application that would perform functionality and ultimately save the data(Highly Confidential) in a local server, I am a newbie, I need ideas from you people in the shape of steps that i need to follow for the implementation. I cant expose the main main idea but the thing is store the customer data (in the database placed on server) on the server via android tablets, there will be multiple tablets feeding the data in parallel. I will appreciate if someone would suggest the appropriate tutorials (for webservice creation/usage etc)
