Is there a guide on how I can have users authenticate using their Google+ account through a Android Mobile app?
I read this article regarding Oauth Services. From what I understand is that the service will provide a URL that the app should redirect users to in order to login to the external service. However, I believe Google+ has a native api that allows users to login (native) directly in the mobile device instead of redirecting to a URL. Can DF Oauth service take advantage of this feature?
