Solution 1:

Ok so I found the answer, the scopes must be written like this:

Stringscopes="oauth2:"
                + Scopes.PLUS_LOGIN
                + " "
                + Scopes.PROFILE;

And the endpoint differs from android to iOS

'https://www.googleapis.com/oauth2/v1/tokeninfo?id_token='; //for iOS
'https://www.googleapis.com/oauth2/v1/tokeninfo?access_token='; //for android
