Unity Play Games 无法进行身份验证

Question

I have a issue with play games services and unity. I've done everything by the documentation. I'm a tester, testing is allowed and I've changed the sha1 in api console to the one used by the app. I'm using code from the docs and examples so here is a brief:

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

Debug.Log("Authenticating...");
Social.localUser.Authenticate((bool success) =>
{
    if (success)
    {
        Debug.Log("Welcome " + Social.localUser.userName);
    }
    else
    {
        Debug.Log("Authentication failed.");
    }
});

When I build the app in development mode the Play Games popup appears, starts loading and disappears and gives me a Authentication failed message. But when I build the app without the development mode nothing happens and I get the authentication failed message instantly. And yes I'm the correct sha1 key.

Please help me

I did a number of things and finally got it to work. I cannot be sure if they all contributed to solving this issue so here I will list what I did, from greatest to least of my guess of their relevance:

1. Match the SHA-1 certificates. If you are using an app downloaded from Play Store use the "app signing certificate", else use the upload certificate. These are found in the Play Console under YourApp/Release Management/App Signing. As a note, if you are building from Unity directly to your device, you should make sure that you are building with the same key used to upload to Google Play. More info here

2. If you are using a custom config and are requesting things such .RequestServerAuthCode(false) , you must create an additional Web App . Go to your console project, and under create credentials choose OAuth client ID , and then select Web App .

3. If using internal testing, make sure to authorize accounts in the Play Console under Game Services/Your App/Testing.

4. Try disabling Anti-Piracy in the Play Console under Game Services/Your App/Linked Apps/Your App. Only do this if you are testing app outside Google Play. I think if you are logging in using verified test accounts this doesn't matter.

Edit: Publishing Game Services is required even for testing.. at least that seemed to be the case for me to get it working.

5. Try clearing the cache of your App on your device, I ran into this problem again and this solved it for me.

I finally think I have got it fixed for good.. after nearly a month later. :o Hope this helps.

Google Services can be published/unpublished separately from your app. Check if they are correctly published doing the following:

1. Google Play Console
2. Game services
3. Select your game
4. Publishing

Check if Game Services are published.
