Thread: College project: XML file from PC to Android

I am a novice Java developer, although I understand the concepts of OOP and the syntax of Java. So far I have developed only a few backend systems using Eclipse.
I am in college and am in the middle of a large project.
I want to make a computer program which can send XML files to picked up by an app on Android 2.1 or greater.
I have absolutely no idea how to do this, so I'd be really greatful for detailed explainations of what it is I have to do.

Many thanks for your help.

EDIT:
Maybe it would help if I gave you a little more detail?
I'm designing software for a computer in C# which will take input from the user and save it to a server, which can be checked, downloaded, viewed and edited by an Android app - which can then send back the newly edited data.

Connecting to servers is something I've never tried before.
I'll also need to know how to read and write data - although that I can almost figure out on my own.
