[aerogear-dev] Implementing AuthzModule (Android)

Hey I need to implement AuthzModule to modify some of its features which i am not getting in Oauth2AuthzModule. Spec I want to use key/secret instead of access token. But wanna use Authzmodule only coz then I have to feed that to pipe and found Authz more comfortable then Auth. If you have any example for that it will be very helpful
