I have developed a game, and on iOS integrated it with Game Center. I also maintain a
local high score at my own server, and uses the Game Center ID and username for
this high score on iOS.
How can I go about the same on Android? It does not seem that there is integration to
Google+ yet, is there some other way for the user to sign in to my application,
so I have a unique username / ID for the users.
I know that I can use open game centers like OpenFeint, but thay would mean a lot of work,
for a lot of features I do not need. Also I could implement my Own Auth system,
but that also seems like overkill.
