### Build Unity Plugin with Gradle

Source: https://github.com/thaina/google-signin-unity/blob/newmigration/README.md

This command builds the Google Sign-In Unity plugin using Gradle. It compiles the support AAR library, packages the plugin into a .unitypackage, and creates a separate package for the sample scene and script. Lint warnings are treated as errors during the build.

```bash
./gradlew -PlintAbortOnError build_all
```

### Configuring Google Sign-In Dependencies (XML)

Source: https://github.com/thaina/google-signin-unity/blob/newmigration/README.md

This XML file in Unity allows for the customization of Google Sign-In dependencies. Uncommenting specific entries, like the 'play-services-games' dependency, enables features such as using the Play Games Services Gamer profile for signing in.

```xml
<dependencies>
    <!-- Uncomment the play-services-games dependency to use the Play Games Services Gamer profile -->
    <!-- <androidPackage spec="com.google.games:games">0.10.4</androidPackage> -->
</dependencies>
```

            RequestEmail = true,
            RequestProfile = true,
            RequestIdToken = true,
            RequestAuthCode = true,
            // must be web client ID, not android client ID
            WebClientId = "XXXXXXXXX-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com",
#if UNITY_EDITOR || UNITY_STANDALONE
            ClientSecret = "XXXXXX-xxxXXXxxxXXXxxx-xxxxXXXXX" // optional for windows/macos and test in editor
#endif
        };

### Configure Google Sign-In and Authenticate with Firebase

Source: https://github.com/thaina/google-signin-unity/blob/newmigration/README.md

This snippet demonstrates how to configure Google Sign-In to request an ID token and use it to authenticate with Firebase Auth. It handles the sign-in process and creates a Firebase credential from the obtained ID token.

```csharp
GoogleSignIn.Configuration = new GoogleSignInConfiguration {
  RequestIdToken = true,
  // Copy this value from the google-service.json file.
  // oauth_client with type == 3
  WebClientId = "1072123000000-iacvb7489h55760s3o2nf1xxxxxxxx.apps.googleusercontent.com"
};

Task<GoogleSignInUser> signIn = GoogleSignIn.DefaultInstance.SignIn ();

TaskCompletionSource<FirebaseUser> signInCompleted = new TaskCompletionSource<FirebaseUser> ();
signIn.ContinueWith (task => {
  if (task.IsCanceled) {
    signInCompleted.SetCanceled ();
  } else if (task.IsFaulted) {
    signInCompleted.SetException (task.Exception);
  } else {

    Credential credential = Firebase.Auth.GoogleAuthProvider.GetCredential (((Task<GoogleSignInUser>)task).Result.IdToken, null);
    auth.SignInWithCredentialAsync (credential).ContinueWith (authTask => {
      if (authTask.IsCanceled) {
        signInCompleted.SetCanceled();
      } else if (authTask.IsFaulted) {
        signInCompleted.SetException(authTask.Exception);
      } else {
        signInCompleted.SetResult(((Task<FirebaseUser>)authTask).Result);
      }
    });
  }
});

### Handle Google Sign-In with Task Continuations in Unity

Source: https://context7.com/thaina/google-signin-unity/llms.txt

This C# code snippet demonstrates how to handle Google Sign-In using Task continuations in a Unity project. It allows for handling authentication results without async/await. The `OnAuthenticationFinished` method is executed after the sign-in task completes, handling potential errors or a successful sign-in.

```csharp
using Google;
using System;
using System.Collections.Generic;
using System.Threading.Tasks;
using UnityEngine;
using UnityEngine.UI;

public class SignInSample : MonoBehaviour
{
    public Text statusText;

    private GoogleSignInConfiguration configuration;

    void Awake()
    {
        configuration = new GoogleSignInConfiguration {
            WebClientId = "123456789-abcdefghijklmnopqrstuvwxyz123456.apps.googleusercontent.com",
            RequestIdToken = true,
            RequestEmail = true,
            RequestProfile = true
        };
    }

    public void OnSignIn()
    {
        GoogleSignIn.Configuration = configuration;
        statusText.text = "Signing in...";

        GoogleSignIn.DefaultInstance.SignIn()
            .ContinueWith(OnAuthenticationFinished, TaskScheduler.FromCurrentSynchronizationContext());
    }

    internal void OnAuthenticationFinished(Task<GoogleSignInUser> task)
    {
        if (task.IsFaulted)
        {
            using (IEnumerator<Exception> enumerator = task.Exception.InnerExceptions.GetEnumerator())
            {
                if (enumerator.MoveNext())
                {
                    GoogleSignIn.SignInException error = (GoogleSignIn.SignInException)enumerator.Current;
                    statusText.text = $"Error: {error.Status} - {error.Message}";
                    Debug.LogError($"Sign-in failed: {error.Status}");
                }
                else
                {
                    statusText.text = $"Unexpected exception: {task.Exception}";
                }
            }
        }
        else if (task.IsCanceled)
        {
            statusText.text = "Sign-in canceled by user";
            Debug.Log("User canceled sign-in");
        }
        else
        {
            GoogleSignInUser user = task.Result;
            statusText.text = $"Welcome {user.DisplayName}!";
            Debug.Log($"Successfully signed in: {user.Email}");
            Debug.Log($"User ID: {user.UserId}");
            Debug.Log($"ID Token: {user.IdToken}");
        }
    }

### Authenticate with Firebase using Google Sign-In in Unity (async/await)

Source: https://context7.com/thaina/google-signin-unity/llms.txt

This C# code snippet demonstrates how to authenticate a user with Firebase using Google Sign-In in a Unity project. It uses the Google Sign-In plugin and the Firebase Authentication SDK. The method `SignInWithGoogle` handles the authentication process using async/await.

```csharp
using Google;
using Firebase.Auth;
using System.Threading.Tasks;
using UnityEngine;

public class FirebaseGoogleAuth : MonoBehaviour
{
    private FirebaseAuth auth;

    private void Start()
    {
        auth = FirebaseAuth.DefaultInstance;
    }

    public async Task<FirebaseUser> SignInWithGoogle()
    {
        // Configure Google Sign-In to request ID token
        GoogleSignIn.Configuration = new GoogleSignInConfiguration {
            RequestIdToken = true,
            // Copy this value from google-services.json oauth_client with type == 3
            WebClientId = "123456789-abcdefghijklmnopqrstuvwxyz123456.apps.googleusercontent.com"
        };

        try
        {
            // Perform Google Sign-In
            GoogleSignInUser googleUser = await GoogleSignIn.DefaultInstance.SignIn();
            Debug.Log($"Google sign-in successful: {googleUser.Email}");

            // Create Firebase credential from Google ID token
            Credential credential = GoogleAuthProvider.GetCredential(googleUser.IdToken, null);

            // Sign in to Firebase with the credential
            AuthResult authResult = await auth.SignInWithCredentialAsync(credential);
            FirebaseUser firebaseUser = authResult.User;

            Debug.Log($"Firebase authentication successful");
            Debug.Log($"User ID: {firebaseUser.UserId}");
            Debug.Log($"Display Name: {firebaseUser.DisplayName}");
            Debug.Log($"Email: {firebaseUser.Email}");

            return firebaseUser;
        }
        catch (GoogleSignIn.SignInException googleEx)
        {
            Debug.LogError($"Google Sign-In failed: {googleEx.Status} - {googleEx.Message}");
            throw;
        }
        catch (System.Exception firebaseEx)
        {
            Debug.LogError($"Firebase authentication failed: {firebaseEx.Message}");
            throw;
        }
    }

    public async void OnGoogleSignInButtonClick()
    {
        try
        {
            FirebaseUser user = await SignInWithGoogle();
            // Navigate to main game scene after successful authentication
            UnityEngine.SceneManagement.SceneManager.LoadScene("MainGame");
        }
        catch (System.Exception ex)
        {
            Debug.LogError($"Authentication failed: {ex.Message}");
            ShowErrorMessage("Failed to sign in. Please try again.");
        }
    }

    private void ShowErrorMessage(string message)
    {
        // Display error to user
        Debug.Log(message);
    }
}
