Android Server

Hello,

I am a student from UC Berkeley and I was wondering if it was possible to have an android server. And if so, do you have any example code that I can look at?

Thank you very much
Daniel

    here is a simple server i made using the basic printer example in the ice manual that displays a notification when a new message is received. Im not sure how to run it on the emulator, because I don't know what host name to give to the client. I just run it on my phone using my wireless home network. Then use the local ip address of the phone as the host name.
