Google Play Game Services Sign In callback

I try to setup google play game service in my cocos2d-x game. I use for this BaseGameActivity.java and GameHelper.java files, so my main class is inherited from BaseGameActivity.
When I call mHelper.beginUserInitiatedSignIn() it show google play activity, and then hide it. But callbacks (onSignInSucceeded and onSignInFailed) not called. When I try call mHelper.beginUserInitiatedSignIn() again it send me massage “GameHelper WARNING: beginUserInitiatedSignIn() called when already connecting…”.

Maybe you can use my template: https://github.com/cpinan/Cocos2dX_GooglePlayGamesServices
