Android & Google App engine Federated Login

Question

i'm trying to create an Android app using App Engine backend with Federated Login authentication.

I read this post http://blog.notdot.net/2010/05/Authenticating-against-App-Engine-from-an-Android-app but it seams it only works with Google Accounts. I also tried LeanEngine (http://www.lean-engine.com) but it needs a server side library as well which is not useful because my login logic is already implemented (and difficult to change).

I need a simple way to create the login mechanism on Android. Any idea what I could use ?

Federated Login is web-based so you will need to use WebView in your Android app to show login & confirmation web pages inside your app.

Also, Federated Login is OpenID based so it will only work with OpenID auth providers - AFAIK out of the big guys only Google, Yahoo and MySpace support it.
