Has anyone created an Android app with server/database integration?

If so, how are you supposed to communicate with the server? I'm accustomed to using SOAP/asmx web services on regular websites. But apparently Android apps don't do asmx web services.

So, I have to change my mindset.

For starters, the app needs to let people to take a picture and then that picture will display on the phone. I have a website for this, now I want to create an Android version. On the Android side, so far, I've just created a sample app with just three buttons that go to their own separate screens.

I now need to do three things essentially:

1) Login - I imagine there is a conventional, best practices, way to do this.
2) Display a picture on the server. I imagine this could simply be done by using a URL with the picture ID in the querystring?
3) The hardest part would be taking a picture on the phone and then uploading it to the server. Normally I'd use an HTML file object but I'm not sure how this would be done with Android.

It is possible I'll figure some of this stuff out by Googling around, by the time I get a response, but it is always nice to be able to discuss these things with a person who's done it before.

Thanks!
