Firebase电子邮件和密码验证与Android - 用户注册 [英] Firebase Email and Password Authentication with android - User sign up
问题描述
最近为我的应用程序创建了一个简单的注册页面，该页面采用了电子邮件和密码的两个值，检查它们是否有效，然后将它们传递给firebase函数以创建用户。值正在正确传递，但是，我总是收到消息注册失败。 firebase连接处于活动状态，我允许用户使用电子邮件和密码验证进行注册。
Recently created a simple sign up page for my application, the page takes the two values of email and password, checks they are valid then passes them into a firebase function to create the user. The values are being passed correctly, however, I always get the message saying "Registration Failed". The firebase connection is active and I have allowed for users to sign up using email and password authenication.
我认为这是我的 build.gradle 文件的问题，可能有错误的依赖关系，但是，我我是Firebase的新手，无法解决这个问题。
I feel it is an issue with my build.gradle files, maybe having the wrong dependencies, however, I am new to Firebase and can't figure this out.
下面是我的Register表单，build.gradle文件和错误的控制台日志。任何帮助将不胜感激。
Below is my Register form, build.gradle files and a console log of the error. Any help would be greatly appreciated.

如果我更换了，这是我收到的错误消息在else循环中登录失败文本。
This is the error message I get if i replace the "login failed" text in the else loop.

推荐答案
与OP交谈后，错误是：
After speaking with OP, the error was:
我/错误是：发生内部错误。 [访问未配置。之前或已禁用Google Identity Toolkit API尚未在项目248549959996中使用。访问console.developers.google.com/...启用它，然后重试。如果您最近启用了此API，请等待几分钟，以便将操作传播到我们的系统并重试。 ]
I/error is: An internal error has occurred. [ Access Not Configured. Google Identity Toolkit API has not been used in project 248549959996 before or it is disabled. Enable it by visiting console.developers.google.com/… then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry. ]
要解决这个问题，他必须启用google identity toolkit api。
To solve it he had to enable the google identity toolkit api.
另外最好添加以下内容以便能够确切地知道问题是什么：
Also it is better to add the below to be able to know what exactly the problem is:
在你的其他地方添加这个，你会得到更清楚的错误：
Add this in your else, you will get the error more clearer:
Toast.makeText(RegisterPage.this, "User Authentication Failed: " + task.getException().getMessage(), Toast.LENGTH_SHORT).show();
或将其添加到日志：
Log.i("error is :", task.getException().getMessage());
