I am a fresh developer on Googles Android Platform - my HTC Desire arrived last week.
Now i need a way to sign in to my existing application (Java, currently running on jetty). The server Application is developed using spring security 3.0.2
In my case, i want to support the following: If a user has set up his Android phone with a googlemail/google-Account (and most users do) i want to use this account credentials to automagically log in to my server app.
Is there any Android framework supporting that use-case? Or are there any alternatives?
I read: http code.google.com intl/de-DE/apis/accounts/docs/OpenID.html
How we do sign in with an app on google AppEngine is described here: http://blog.notdot.net/2010/05/Authenticating-against-App-Engine-from-an-Android-app
