Question

我正在学习使用firebase开发应用程序。但不知怎的，我无法注册我的用户。我仔细研究了一切，不知道错误是什么。它一直促使我＆＃34;未能注册＆＃34;但我不确定是什么错误。我已确保已启用电子邮件/密码登录方法。我已经确保google play版本高于firebase（＆＃39; com.google.firebase：firebase-auth：11.0.4＆＃39;）。有人可以帮我这个。谢谢

更新：我收到错误消息

不要在android studio中使用firebase工具创建。在firebase控制台中手动创建，现在可以正常工作。

为什么我没有使用FirebaseAuth注册用户？
