Question

I am trying to make simple game with Google Play Games Services, but I failed to sign in to Google Play Games.

I get this error:

Answer 1

In my case.I setted one test account,but my device has an default account which is another,that's why I got this error.My mistake but Why can't google gives us an more obvious error report?

Here is how I worked this out.All my test was under debug version using test account. I delete the project, both in google play develper console and google Api console.And recreate one as mentioned by others on stackoverflow.But this does't help.I redo this and ends up in vane.

I cheked found in log these same words:

03-09 16:15:39.897: E/GameAgent(1225): Unable to retrieve application xxxxxxx from network 03-09 16:15:39.902: E/GameAgent(1225): Application ID xxxxxxx is not associated with package com.gyj.pub.gpgsDemo. Check the application ID in your manifest. 03-09 16:15:39.906: E/CheckGameplayAcl(23917): Unable to load metadata for game 03-09 16:15:39.906: W/SignInActivity(23917): onSignInFailed()...

one more,I checked all the 3 elements below ,decide whether the client apk is conform with Google Play Deverloper Console's configuration. 1.package name .It is all the same. 2.Certification SHA1 fingerprint.(debug and release). 3.test Account.

Even at that time I did not realize that I haven't input an account during my tests,How does the device know which account is attend to sign in? I tried an other account.I added this account which has setted in sonsole as Test Account to the device,relaughched the TypeANumber app.It showed me a view to choose one from the two accounts.Suddently I got it.
