I am working on a multiplayer game supporting Android and IOS.
For IOS Game-Center seems promising. But its IOS only.
OpenFeint could be a option, but now GREE has stopped supporting it.
Is there any other multi-platform SDK which I can use for both IOS and Android?
---------EDIT------
I could not find any good service which provides their own server and SDK for both IOS and android. So finally I chose to go with my own server on AWS-EC2 + python tornado + Websocket. If anyone want to know more plz contact...
