[X.Auth] Google unsupported_response_type

Hey guys,

I've been trying to authenticatie my users via Google using the Xamarin.Auth component. I'm keep recieving the following error: unsupported_response_type while using the following code:

var auth = new OAuth2Authenticator (
                clientId: "myId",
                scope: "email",
                authorizeUrl: new Uri ("https://accounts.google.com/o/oauth2/auth"),
                redirectUrl: new Uri ("http://localhost"));

What am I doing wrong here?

Thanks in advance!
