Server communication that is compatible with Android

[Bantak]

Hi,

I want to develop a application with Android and GWT as frontends and
a application server as backend.
My question is what is the easiest way to communicate with the server
and I want to reuse some of the code for Android (especially the
model).

I probably will use Jetty as a server and I specifically do not want
to use Google AppEngine.

Can I use the RequestFactory (which I think is used to communicate
with AppEngine) on a local server? Does anybody know if I can use it
with Android too?

The Google IO presentation about App Engine Connected Android Support
[1] seems perfect. But I have to run my server on my PC.

Absolutely!

RF is not tied to AppEngine at all (we do use it since its early beginnings, two years ago, as part of GWT 2.1-M1, on "local" Jetty servers). The server-side of RF is "just a servlet".

And there's a "pure JVM" version that can run on Android (use RequestFactorySource instead of GWT.create(), and init with a UrlRequestTransport –or a RequestTransport of your own based on Apache HttpClient– that point to your server)
