android - firebase 错误 W/DynamiteModule : Local module descriptor class for com. 找不到 google.firebase.auth

Question

• 我尝试基于登录/注册帐户构建应用。
• 我创建了它的 Firebase 并通过电子邮件启用了身份验证。
• 我添加了 google-play-services.json 文件。

• 我加了

  apply plugin: 'com.google.gms.google-services'
  compile 'com.google.firebase:firebase-auth:10.0.1'
  

  在 build.gridle(app) 中

  然后在我添加的模块中

  classpath 'com.google.gms:google-services:3.0.0'
  

  这是我的代码

  public class splashscr extends Activity implements View.OnClickListener{
  
  TabHost tab ;
  Button logbtn,signup;
  EditText email,password,signupemail,signuppassword;
  private FirebaseAuth firebaseAuth;
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      tab =(TabHost) findViewById(R.id.tabhost);
      logbtn = (Button) findViewById(R.id.btn_login);
      signup = (Button) findViewById(R.id.btn_signup);
      password = (EditText)findViewById(R.id.input_password);
      email = (EditText)findViewById(R.id.input_email);
      signupemail =(EditText)findViewById(R.id.signupinput_email);
      signuppassword = (EditText) findViewById(R.id.signupinput_password);
      firebaseAuth = FirebaseAuth.getInstance();
      logbtn.setOnClickListener(this);
      signup.setOnClickListener(this);
      tab.setup();
  
      TabHost.TabSpec spec = tab.newTabSpec("tag1");
      spec.setIndicator("",getResources().getDrawable(R.drawable.loginpic));
      spec.setContent(R.id.tab1);
      tab.addTab(spec);
  
      spec = tab.newTabSpec("tag2");
      spec.setIndicator("",getResources().getDrawable(R.drawable.signupp));
      spec.setContent(R.id.tab2);
      tab.addTab(spec);
  }
  @Override
  public void onClick(View view) {
     final Intent I = new Intent(this,HomeActivity.class);
      final String emailout = signupemail.getText().toString();
      final String passwordout = signuppassword.getText().toString();
      if (view == signup){
          (firebaseAuth.createUserWithEmailAndPassword(emailout,passwordout)).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
              @Override
              public void onComplete(@NonNull Task<AuthResult> task) {
                  if (task.isSuccessful()){
                      Toast.makeText(splashscr.this, "تم تسجيلك بنجاح ", Toast.LENGTH_SHORT).show();
                      startActivity(I);
                      finish();
                  }
                  else
                  {
                      Log.e("ERROR", task.getException().toString());
                      Toast.makeText(splashscr.this, "فشل التسجيل", Toast.LENGTH_SHORT).show();
                  }
                  Toast.makeText(splashscr.this,emailout+passwordout, Toast.LENGTH_SHORT).show();
              }
          });
      }
  }
  }
  

我得到这个错误:

E/ERROR: com.google.firebase.FirebaseException: An internal error has occurred. [ OPERATION_NOT_ALLOWED ]
W/DynamiteModule: Local module descriptor class for com.google.firebase.auth not found.

怎么了？

尝试将您的客户端与您的 Firebase 应用重新同步，并再次添加 .json 文件。 在 android studio 2.3 中，只需单击工具>firebase，然后在助手中检查您的应用是否已连接。
