Value	Type	Description
webClientId	string	(When the inspector is not configured) Web client ID set in Google Cloud Platform

Main thread and external thread

If an object or function created using UnityEngine or UnityEngine.UI is called from Unity or an external thread, an exception occurs.

When a callback is called to the main thread, a crash may occur if numerous objects are created in the callback, synchronous form BACKND functions cause the game to stop temporarily, or if a heavy action takes place.

Description

Attempts Google login. The result can be checked through the GoogleLoginCallback callback event.
After a successful Google login, you will be automatically logged into the previously selected ID whenever Google login is called.
To reselect the account, call TheBackend.ToolKit.GoogleLogin.Android.GoogleSignOut below.

Example

public void StartGoogleLogin() {
    TheBackend.ToolKit.GoogleLogin.Android.GoogleLogin(true, GoogleLoginCallback);
}

private void GoogleLoginCallback(bool isSuccess, string errorMessage, string token) {
    if (isSuccess == false) {
        Debug.LogError(errorMessage);
        return;
    }
    
    Debug.Log("Google token : " + token);
    var bro = Backend.BMember.AuthorizeFederation(token, FederationType.Google);
    Debug.Log("Federation login result : " + bro);
}
