I would like to retrieve an offline access token for a web back-end as described here:
https://developers.google.com/identity/protocols/CrossClientAuth#androidIdTokens
That page gives the following scope as an example:
oauth2:server:client_id:[client id]:api_scope:[scopes]
After replacing the client id and scopes with my own, I was able to use this successfully with GoogleAuthUtil.getToken(), but I have been unable to make it work with the Google Identity Toolkit for Android. It seems you cannot properly format the scope by using GitkitClientBuilder.addScopes(), since the toolkit adds its own scopes on top of yours.
Is it possible to get an offline access token using the Google Identity Toolkit for Android?
