Anyway to Authenticate a user using Google Apps in an Android application?

Question

I was wondering if anyone knows of a way I can Authenticate a Google Apps User in a Android Application?

One approach I know of is to take could take their username and password in a android view, and use the clientLogin interface (http://code.google.com/apis/accounts/docs/AuthForInstalledApps.html).

However I was wondering if there was a different approach, maybe pushing to a browser window where it would show the google login for that domain, but I would not know how to get the details back to the application, after the authentication is done.

Any ideas on how it would be done?

Answer 1

You could also try using OAuth. It's supported by Google Apps, and has a Java client library.

Answer 2

I wrote up how to get a google auth token from android (works fine in any java really) so you can call app engine hosted web services as an authenticated google user:
