Google Play not able to sign-in into Clash of Clans app I'm playing Clash of Clans on my Android device, and I have already downloaded Google Play and signed in as well.  But when I am trying to log-in into Clash of Clans the loading ring just rotate for a while, but I am not able to sign in and save the game. 

What should I do now?
Have you installed Google Play Games? It should be signed in,  to allow you to log in Clash of Clans to Google Play Games.
