Social.localUser.Authenticate always returns false

[tucsok007]

Hi,

I'm facing an issue with authentication: Social.localUser.Authenitcate always returns false. My signing keys are matching. I have my email added as a tester. The project is still in test mode so it's not published. I am trying to test on android. I was wondering if anyone could help me to resolve this, please?

Unity version in case if it's needed: 2018.3.0f2.

[legas1]

    PlayGamesClientConfiguration config = new 
    PlayGamesClientConfiguration.Builder().RequestServerAuthCode(false).Build();
    PlayGamesPlatform.InitializeInstance(config);
    PlayGamesPlatform.Activate();

This should be called only once and also without logs I cannot say what the problem is, but try to move this piece of code to Awake or Start method.

I'll try to do it with logs but the SignIn coroutine is called from the start method. I needed to do it this way beacuse otherwise firebase authentication would start before google play sign in is finished as it's a lambda expression.

[tucsok007]

    PlayGamesClientConfiguration config = new 
    PlayGamesClientConfiguration.Builder().RequestServerAuthCode(false).Build();
    PlayGamesPlatform.InitializeInstance(config);
    PlayGamesPlatform.Activate();

I get DEBUG: Starting Auth Transition. Op: SIGN_IN status: ERROR_NOT_AUTHORIZED

[tucsok007]

I solved the issue. The problem was that I tried debugging using the original apk and I didn't knew that google resigns the apk. After downloading the deprived version and installing that on my device everything was working fine.
