android - "task.isSuccessful"在CreatewithUseremailandpassword 中总是返回false

Question

我已使用 createUserWithEmailAndPassword 方法注册用户，他们已在我的 firebase 项目中注册(我可以看到他们的信息)。但是，当我尝试使用创建的电子邮件和密码登录时，task.isSuccessful 方法始终返回 false，并且每次都运行 else 语句。

登录注册码:

private Button buttonRegister;
private EditText editTextEmail;
private EditText editTextPassword;
private TextView textViewSignin;

private ProgressDialog progressDialog;
private FirebaseAuth firebaseAuth;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    progressDialog=new ProgressDialog(this);
    firebaseAuth= FirebaseAuth.getInstance();


    buttonRegister = (Button) findViewById(R.id.buttonRegister);

    editTextEmail=(EditText) findViewById(R.id.editTextEmail);
    editTextPassword=(EditText) findViewById(R.id.editTextPassword);

    textViewSignin=(TextView) findViewById(R.id.textViewSignin);

    buttonRegister.setOnClickListener(this);
    textViewSignin.setOnClickListener(this);

    if(firebaseAuth.getCurrentUser()!=null){
        //start the profile activity
        finish();
        startActivity(new Intent(getApplicationContext(), ProfileActivity.class));
    }


}

private void registerUser(){
    String email=editTextEmail.getText().toString().trim();
    String password=editTextEmail.getText().toString().trim();

    if(TextUtils.isEmpty(email)){
        Toast.makeText(this, "Please enter E-mail first", Toast.LENGTH_SHORT).show();
        return;
    }

    if(TextUtils.isEmpty(password)){
        Toast.makeText(this, "Please enter password first", Toast.LENGTH_SHORT).show();
        return;
    }

    progressDialog.setMessage("Registerring User......");
    progressDialog.show();


    firebaseAuth.createUserWithEmailAndPassword(email, password)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    progressDialog.dismiss();
                    if(task.isSuccessful()){
                        finish();
                        startActivity(new Intent(getApplicationContext(), ProfileActivity.class));
                    }
                    else{
                        Toast.makeText(MainActivity.this, "Unable to Register! Please try again.", Toast.LENGTH_SHORT).show();
                    }
                }
            });


}

@Override
public void onClick(View v) {
    if(v == buttonRegister){
        registerUser();
    }

    if(v == textViewSignin){
        finish();
        startActivity(new Intent(this, LoginActivity.class));
    }

  }

您是否检查过 firebase 在返回 false 时给出的异常？请使用以下代码检查当时发生了什么异常:

task.getException() //which returns the exception that caused the Task to fail.

检查并更新您遇到的异常，以便我们可以帮助您，或者您可以提出解决问题的想法？
