Unity游戏中FirebaseGoogle登录错误

1. 确保您已经设置了Firebase和Google登录。
2. 确保您的API密钥和OAuth 2.0客户端ID在Firebase控制台上正确设置。
3. 确保您的AndroidManifest.xml文件包含以下权限: <uses-permission android:name="android.permission.INTERNET" />
4. 如果出现以下错误，表示您的包名不匹配或SHA-1散列值未正确设置: E/FirebaseAuth: [GetAuthDomainTask] Error getting project Config. Failed with {0} E/FirebaseAuth: [SmsRetrieverHelper] SMS verification code request failed: unknown status code: 17093 null
5. 如果Android SDK未正确安装，您可能会看到以下错误消息: Error building Player: CommandInvokationFailure: Failed to update Android SDK package list.
6. 如果您的Unity版本低于2018.4，您可能需要使用Firebase SDK 4.x版本。
7. 确保使用的Android支持库版本与Firebase SDK版本兼容。

以下是示例代码：

Firebase.Auth.FirebaseAuth auth = Firebase.Auth.FirebaseAuth.DefaultInstance;

GoogleSignInConfiguration config = new GoogleSignInConfiguration { WebClientId = "YOUR_WEB_CLIENT_ID_HERE", RequestIdToken = true, RequestEmail = true, };

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DefaultSignIn) .RequestIdToken("YOUR_WEB_CLIENT_ID_HERE") .RequestEmail() .Build();

GoogleSignInClient client = GoogleSignIn.GetClient(this, gso);

TaskCompletionSource<FirebaseUser> signInCompleted = new TaskCompletionSource<FirebaseUser>();

GoogleSignInResult result = await Auth.GoogleSignInApi.SilentSignInAsync(googleApiClient);

if (result.IsSucceeded) { string idToken = result.SignInAccount.IdToken; AuthCredential credential = Firebase.Auth.GoogleAuthProvider.GetCredential(idToken, null);

auth.SignInWithCredentialAsync(credential).ContinueWith(task =>
{
    if (task.IsCanceled)
    {
        signInCompleted.SetCanceled();
    }
    else if (task.IsFaulted)
    {
        signInCompleted.SetException(task.Exception);
    }
    else
    {
        FirebaseUser firebaseUser = task.Result;
        signInCompleted.SetResult(firebaseUser);
    }
});

} else { result.StartResolutionForResult(this, GOOGLE_SIGN_IN_REQUEST_CODE); }
