在Android中开发实时多人游戏

Question

I am facing problem in signing in using the google real time muleiplayer api's even after following all steps throughly as given in the documentation. Following is the link from where I have referred: https://developers.google.com/games/services/android/init . I am not getting any error but my main activity extends BaseGameActivity when i start my game it calls onSignInFailed() automatically but i am calling the beginUserInitiatedSignIn() method from BaseGameActivity which is used for initialization of sign in on the button click none of the overridden methods gets called not even onSignInFailed() nor onConnectionFailed() .

Answer 1

It's normal for it to call onSignInFailed on startup if have never signed in before. That's working as intended. Then, you should call beginUserInitiatedSignIn when your button is clicked, and then either onSignInFailed on onSignInSucceeded should be called.

I'd suggest putting some print statements around your code and BaseGameActivity to figure out what methods are being called to figure out what's happening.

By the way, the most common cause for sign-in errors is having a Client ID that's incorrectly set up. I'd recommend taking a look at the troubleshooting guide to see if there is a problem with your setup:
