I am trying to authenticate the user following this gist by Ian Barber. The button asks for the user account, but it never gets to show the authorization dialog and instead exits with the message "An internal error ocurred". Logcat shows this:
W/GLSUser ( 4353): Status from wire: INVALID_KEY status: null
W/GLSUser ( 4353): Status from wire: INVALID_KEY status: null
E/GLSUser ( 4353): Empty consent data
I/GLSUser ( 4353): GLS error: INVALID_KEY icoloma@gmail.com oauth2:https://www.googleapis.com/auth/plus.login
W/GLSUser ( 4353): Status from wire: Unknown status: UNKNOWN
The certificate used to sign my app is the same configured at my Google API Console page, and the package name is also the same.
