Android - Firebase快速入门电子邮件/密码验证演示不起作用 [英] Android - Firebase Quickstart Email/Password Auth demo doesn't work

问题描述

所以，这里有几个类似的问题，但是他们没有一个能为我提供解决方案。

我正在使用从Github下载的快速入门演示。今天下载。我没有在演示代码中改变任何东西。

一些常见的错误（从我读到的）我已经解决：

• 我已经在Firebase控制台中创建了使用
  可下载的json文件（使用软件包名称创建）的项目。我提供了
  我的SHA1指纹。
  

• 检查电子邮件/密码登录方法。

服务和Google Repository更新和安装（来自Android
Studio SDK管理器）


• 在我的设备上，Google Play服务是版本9.4.52如果我在Firebase控制台中启用匿名登录选项，则可以匿名登录演示应用程序。但电子邮件/密码将无法正常工作。
  
  

  编辑：不知道我是否正确地做了这件事，但是我在Logcat中得到了这些信息
  
  

    D / EmailPassword：createAccount：[e-mail] 
   W / DynamiteModule：未找到com.google.firebase.auth的本地模块描述符类。 
   W / ResourcesManager：资产路径/system/framework/com.android.media.remotedisplay.jar不存在或不包含任何资源。 
   W / ResourcesManager：资产路径/system/framework/com.android.location.provider.jar不存在或不包含任何资源。 
   D / EmailPassword：createUserWithEmail：onComplete：false 
    

  
  

  解决方案

  logcat 输出显示创建用户帐户失败。 文档表明这可能发生，原因如下：

  
  
  
  
  
  • 密码不够强（少于6个字符）
  
  
  • 电子邮件地址格式不正确
  
  
  • 已存在具有给定电子邮件地址的帐户
  
  
  
  
  

  在 createUserWithEmailAndPassword（）的完成监听器中添加一个 Log 失败的原因是：
  
  

    @Override 
   public void onComplete（@NonNull Task< AuthResult> task）{
   Log.d（TAG，createUserWithEmail：onComplete：+ task.isSuccessful（））; 
   
   //如果登录失败，则向用户显示一条消息。如果登录成功
   //将通知auth状态侦听器，并且处理
   //登录用户的逻辑可以在侦听器中处理。 
   if（！task.isSuccessful（））{
   Log.d（TAG，onComplete：Failed =+ task.getException（）。getMessage（））; // Add this 
   
   Toast.makeText（EmailPasswordActivity.this，R.string.auth_failed，
   Toast.LENGTH_SHORT）.show（）; 
  } 
   
   // [START_EXCLUDE] 
   hideProgressDialog（）; 
   // [END_EXCLUDE] 
  } 
    

  
  

  So, there are a couple similar questions on here, but none of them have a working solution for me.

  I am using the Quickstart demo downloaded from Github. Downloaded today. I've changed nothing in the demo code.

  Some common mistakes (from what I've read) that I've addressed:

  • I have the project created in the Firebase Console with the downloadable json file (created with package name). I have provided my SHA1 fingerprint.

  • Email/Password sign-in method is checked.

  • I have Google Play Services and Google Repository updated and installed (from the Android Studio SDK manager)

  • On my device Google Play Services is version 9.4.52

  If I turn on the Anonymous sign-in option in the Firebase Console, I'm able to successfully Anonymously sign in on the demo app. But Email/Password will not work.

  Edit: Not sure if I'm doing this right, but I got these in Logcat

  D/EmailPassword: createAccount:[e-mail]
   W/DynamiteModule: Local module descriptor class for com.google.firebase.auth not found.
   W/ResourcesManager: Asset path '/system/framework/com.android.media.remotedisplay.jar' does not exist or contains no resources.
   W/ResourcesManager: Asset path '/system/framework/com.android.location.provider.jar' does not exist or contains no resources.
   D/EmailPassword: createUserWithEmail:onComplete:false
  

  解决方案

  The logcat output shows that the creation of the user account is failing. The documentation indicates this can happen for these reasons:

  • the password is not strong enough (less than 6 characters)
  • the email address is malformed
  • there already exists an account with the given email address

  Add a Log statement to the completion listener for createUserWithEmailAndPassword() to see what the failure reason is:

  @Override
  public void onComplete(@NonNull Task<AuthResult> task) {
      Log.d(TAG, "createUserWithEmail:onComplete:" + task.isSuccessful());
  
      // If sign in fails, display a message to the user. If sign in succeeds
      // the auth state listener will be notified and logic to handle the
      // signed in user can be handled in the listener.
      if (!task.isSuccessful()) {
          Log.d(TAG, "onComplete: Failed=" + task.getException().getMessage()); //ADD THIS
  
          Toast.makeText(EmailPasswordActivity.this, R.string.auth_failed,
                  Toast.LENGTH_SHORT).show();
      }
  
      // [START_EXCLUDE]
      hideProgressDialog();
      // [END_EXCLUDE]
  }
