Awhile ago I did for a little Tic Tac Toe game. At that time you could use the Game Center API and on Android it would compile the equivalent code using Google Play Game Services. I was still using my free trial at that time. It really should be turn-based for tic tac toe but I had to use live matches because turn based wasn't supported (not sure if it's supported now).
I'm pretty sure GameKit API required a indy subscription. I'm sure it's still possible but it's not free. I think you could write your own if you use their bridge kit technique (as long as you're willing to code in Java). It looks like Apportable pulled its pricing options down from the site while they are doing BETA (unless I'm looking in the wrong spot). Should be interesting to see how Android development works in SB when the new version comes out.
I hope they have a free option to allow real indy developers to bring games to the Android marketplace. Either that, or it would be nice if Google just bought out Apportable and allowed all developers to write apps in Objective-C (probably will never happen).
