Play-games-plugin-for-unity: Authenticate false with "Authentication canceled"

[rico345100]

When I run my game, Google Play Games Services showing over the game but it just close after a few seconds. Note that my game is published as an internal test and connected with Google Play App which also published.

First, Here's I tried to solve my problem:

1. Checked Signing certifications and SHA-1 certificate
2. Checked tester email is valid (both Google Play Tester and internal tester and confirmed both exists)
3. Saved Games are enabled.
4. Removing EnableSavedGames() doesn't affect at all
5. Downgrade to 0.9.50.
6. Reimport

But none of them worked.

Here's the code I'm trying:

PlayGamesClientConfiguration config = new PlayGamesClientConfiguration.Builder().EnableSavedGames().Build();
PlayGamesPlatform.InitializeInstance(config);
PlayGamesPlatform.DebugLogEnabled = true;
PlayGamesPlatform.Activate();

Social.localUser.Authenticate((bool success) => {
    print("Authentication: " + success);
    m_Authenticated = success;

    if(success) {
        onSuccess();
    }
    else {
        onFailed();
    }
});

When I run Social.localUser.Authenticate, it always returns false. Here's the message from Logcat:

Using Unity 2019.1.0f2 and Play Games for Unity 0.9.64.

[firtinapd]

What do you see on the device? Do you see the banner for the user name and level? Do you have the google play services account created for the user on the phone? If you see the username and level on the banner, it may have actually worked.

Sometimes even if the callback says it failed, it may succeed.

I have a workaround like this for 0.9.64:

(incomplete code, you need to adapt a bit for your case):

        PlayGamesPlatform.Instance.Authenticate((success, message) =>
        {
            if (success)
            {
                AuthenticationSuccessful();
            }
            else
            {
                // Don't give up yet...
                StartCoroutine(WaitForAuthenticationCoroutine());
            }
        }, true);

....

    private const float AuthenticationWaitTimeSeconds = 10;

    private IEnumerator WaitForAuthenticationCoroutine()
    {
        var startTime = Time.realtimeSinceStartup;

        while (!Social.localUser.authenticated)
        {
            if (Time.realtimeSinceStartup - startTime > AuthenticationWaitTimeSeconds)
            {
                // X seconds have passed and we are still not authenticated, time to give up.
                break;
            }

            yield return null;
        }

        if (Social.localUser.authenticated)
        {
            AuthenticationSuccessful();
        }
        else
        {
            AuthenticationFailed();
        }
    }

What do you see on the device? Do you see the banner for the user name and level?

No, I see the Google Play banner is shown, but no player name and icon banner popped up.

Do you have the google play services account created for the user on the phone?

Yes, I checked my account is correct hundreds of times. This is not the first time I'm making Unity game with this plugin. I used the same account every project and tested it with the same account also. But this never happened.

Sometimes even if the callback says it failed, it may succeed.

That sounds exactly should not happen. If that's true, how do I trust callback from authentication and proceed with other steps? Of course, you show the way how to solve it, but man that's really hard to believe.

I'm temporarily fixed this issue by change certification digital fingerprints to uploading certification, not an app-signing certification because I saw some people solved with this approach. Most people said use app-signing certification but it won't work for me. Why?

[harunuysali07]

I have the same problem.
I done what he tried too but not succeded, neither your temporary fix didn't not worked for me.
I have same silly Google Play Animation. and exact same log output no errors just says it's canceled.

[Vukiz]

Same problem here. Any advices how to fix this?

[Vukiz]

So the problem was with Api console project configuration. After I changed SHA-1 key in console to one I'm subscribing my Unity Game it worked fine.

[harunuysali07]

I tried this with both my SHA-1 certificates on Google Play Console :

I tried them one each time :

I tried : This either

Still same on when I download my app on Google Play or Direct build to my phone.

[Jokod]

I have the same problem.. and no solution :'(

[harunuysali07]

So the problem was with Api console project configuration. After I changed SHA-1 key in console to one I'm subscribing my Unity Game it worked fine.

Which one did you used Upload Certificate or App Signing Certificate ?

[BenDevelopment]

I have exactly the same problem, but it works on my phone and it doesn't works on some others.
I have no settings differences between the ones working and the ones not working.
I have no clue how to fix this...

EDIT : My leaderboard worked on my phone, then I have uninstalled the game and installed back, and now, I have that error on my phone (Authantication Canceled). Maybe it can be a possible line of approach for debbugging.

[BenDevelopment]

Ok I've fixed this problem.
The Google Play Game Service API has to know if your application is allowed to use it.
The common way to authorize your application is to add you application SHA1 signature to the API and Service Credentials (ID clients OAuth 2.0) :
https://console.developers.google.com/apis/credentials

BUT :

Once you upload you app bundle to your Google Play Console, Google re-sign you application (ONLY IF YOU HAVE ENABLED "App signing by Google Play")!
So the authorization doesn't match your previous signature (the one you added when you have build with Unity).
The solution is to add the new SHA1 (the one created by Google during the "App signing by Google Play") to the Google Play Game Service Credentials.

You can find the new SHA1 in your application console:

Add this SHA1 here:

You don't have to remove the SHA1 used to sign your app in your Unity build, you can allow both.

PLEASE ADD THIS TO THE DOCUMENTATION

[firtinapd]

Thank you for the above comment, I did not realise you could add multiple SHAs to the app configuration, this will improve our testing and deployment process significantly!

[firtinapd]

One note for the above comment:
After you add the new SHA, you need to go to the game services config for your game ( https://play.google.com/apps/publish/#GameListPlace ) and select the game, select the "Publishing" tab, then publish your changes. Otherwise GPS will not recognize the difference. Forgetting this made me waste a few hours 🤦

Good day!
I'm having a similar problem.

I want to setup Play Games as an auth provider for a Firebase project. I followed this guide https://firebase.google.com/docs/auth/unity/play-games

The Play Games auth step always returns false and the error message is Setting result error status code to: 16

Logcat errors

    (Filename: ./Runtime/Export/Debug/Debug.bindings.h Line: 35)

I then tried to setup a new project through Google Play Console -> Game Services -> Add game without firebase (Not using other Google API tab) and this configuration worked fine.

I guess it's not a problem of this plugin but rather some error in Firebase <-> Play Games integration. I would like to know what this Setting result error status code to: 16 means so I can maybe report this to Firebase support.

Thanks in advance.

[vladislav1muhlisov]

Hello!
I am currently integrating a Google Play Games plugin for unity. I faced the same problem as described above. I tried almost everything from different forums. I started the OAuth consent screen verification process. Finally I finished with recreating project in google play services and in Google API console. But the problem hasn't gone away.

Here is the information about my new Game Sevices and API projects:

1. I created the alpha release. My app is using Google app signing. So the app is signed with production certificate. The SHA-1 certificate has entered correctly in the credentials menu.
   
   

2. The project and OAuth client were automatically generated using the Google Play Services menu options in the Google Play Console.
   

3. The name field is filled in the OAuth consent screen:
   

4. Information in the GPG settings in unity was set correctly:
   

5. I am not using the ProGuard.

6. I added my account to the testers
   
   

I am still continue getting the following error messages in the logcat:

Here is the initialization code:

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

Please help me :(

Yo guys, make sure that you have installed google play services in android studio SDK Manager. After I did it, rebuild unity project — all works fine.

You don't have to remove the SHA1 used to sign your app in your Unity build, you can allow both.

Yo guys, make sure that you have installed google play services in android studio SDK Manager. After I did it, rebuild unity project — all works fine.

Thank you, bro!!! It works now!

好的，我已经解决了这个问题。
Google Play游戏服务API必须知道是否允许您的应用程序使用它。
授权应用程序的常用方法是将应用程序SHA1签名添加到API和服务凭据（ID客户端OAuth 2.0）：https :
//console.developers.google.com/apis/credentials

但是：

将应用程序包上传到Google Play控制台后，Google会对您的应用程序重新签名（只有在您启用“通过Google Play进行应用程序签名”的情况下）！
因此，授权与您之前的签名（使用Unity构建时添加的签名）不匹配。
解决方案是将新的SHA1（由Google在“ Google Play进行应用签名”期间创建的SHA1）添加到Google Play游戏服务凭据中。

您可以在应用程序控制台中找到新的SHA1：

在此处添加此SHA1：

您不必删除在Unity构建中用于对应用程序进行签名的SHA1，可以两者都允许。

请将此添加到文档中

Ok I've fixed this problem.
The Google Play Game Service API has to know if your application is allowed to use it.
The common way to authorize your application is to add you application SHA1 signature to the API and Service Credentials (ID clients OAuth 2.0) :
https://console.developers.google.com/apis/credentials

BUT :

Once you upload you app bundle to your Google Play Console, Google re-sign you application (ONLY IF YOU HAVE ENABLED "App signing by Google Play")!
So the authorization doesn't match your previous signature (the one you added when you have build with Unity).
The solution is to add the new SHA1 (the one created by Google during the "App signing by Google Play") to the Google Play Game Service Credentials.

You can find the new SHA1 in your application console:

I think it's r that you said Google will re-sign for you, I still have this problem, but when I look at the signature through APK, SHA-1 in APK is the same as SHA-1 in the application signature certificate in Google PLAY Console, so I'm not sure if I need to go to the Google APIs Console for OAuth Settings.I'm sorry that my Poor English may bring inconvenience to your reading. Thank you

For me, this issue was caused by the package name being changed by Unity itself.

In "Project Settings-->Player-->Android-->Other Settings-->Identification", there's a new checkbox "Override Default Package Name" which is not automatically selected.
In my case this changed the package name to the default, which is derived from company name, e.g. com.[COMPANY].[APP]

To fix, I simply checked the checkbox and replaced the derived value with my actual package name.

I have lost days to this issue and still can't remedy it after trying everything in this thread.
Mine also says it returned with the error code "Canceled".

I had the same issue and my mistake was that I had put the wrong client ID in the Google Play Games setup inside Unity. I had put the client ID that I had found in the Google Play Console (Play Games Services > Setup and management > Configuration) when the correct one was the client ID of the web client that was in the credentials in the google cloud console: https://console.cloud.google.com/apis/credentials

Doing this helped me resolve my issues. Although, I did try other things, changing the client ID to the web client ID on the cloud console is definitely going to be a step in the right direction for anyone.

My problem was that I had the wrong SHA-1 certificate fingerprints entered.

The app was using a different SHA-1 to the one shown in the developer console and the one in the keystore. On failing to authenticate the actual SHA-1 used was written to logcat:

** To help you debug, here is the information about this app...

Creating a new OAuth client ID using the SHA-1 from the log message solved the problem for me.
