java - Firebase Auth 和 Firebase 数据库不保存 Google 注册

Question

我有一个系统可以将 createUserWithEmailAndPassword 数据保存到实时数据库和身份验证数据库中。但是在使用谷歌登录创建了一个类似的系统之后，没有任何内容会保存到数据库中，也没有任何内容保存到身份验证数据库中。

我试过使用 Log.e，我试过调试应用程序，也试过解码代码...

这里是一些代码:

            }

            @Override

            }
        });

    }

    void LoadinGUI(){

        LoginBtn = (Button) findViewById(R. id. Login_btn);
        RegisterWithEmailBtn = (Button) findViewById(R. id. Register_WithEmail_btn);
        RegisterWithGoogleBtn = (Button) findViewById(R. id. Register_WithGoogle_btn);

    }

}

我希望应用程序将信息保存到实时数据库和身份验证数据库中。这些似乎都不起作用......

登录成功后忘记调用SaveToDataBase。这就是为什么没有日志和数据库条目的原因。
