未添加firebase参考

Question

由于某些原因，数据未添加到firebase数据库中。也许是因为我将数据库设置为测试模式？我不知道。这是之前的工作，但是今天它停止了工作。

    private EditText EditTextFullName, EditTextAge, EditTextEmail, EditTextPassword;


    private TextView registerUser;


    private FirebaseAuth mAuth;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_register);
            mAuth = FirebaseAuth.getInstance();
            Objects.requireNonNull(getSupportActionBar()).hide();


            EditTextFullName = (EditText) findViewById(R.id.fullName);
            EditTextAge = (EditText) findViewById(R.id.age);
            EditTextEmail = (EditText) findViewById(R.id.email);
            EditTextPassword = (EditText) findViewById(R.id.password);



            registerUser= (Button) findViewById(R.id.registerUser);
            registerUser.setOnClickListener(this);

            
    }






    @Override
    public void onClick(View v) {
            switch(v.getId()){
                    case R.id.registerUser:
                            registerUser();
                            break;

            }
    }

    private void registerUser() {
            String email = EditTextEmail.getText().toString().trim();
            String age = EditTextAge.getText().toString().trim();
            String fullname = EditTextFullName.getText().toString().trim();
            String password = EditTextPassword.getText().toString().trim();




            if(password.length() < 6) {
                    EditTextPassword.setError("Min password length should be 6 characters");
                    EditTextPassword.requestFocus();
                    return;
            }


            mAuth.createUserWithEmailAndPassword(email, password)
                    .addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                            @Override
                            public void onComplete(@NonNull Task<AuthResult> task) {




            if(task.isSuccessful()){

                    User user = new User(fullname, age, email);
                    FirebaseDatabase.getInstance().getReference("Users")
                            .child((FirebaseAuth.getInstance().getCurrentUser()).getUid())
                            .setValue(user).addOnCompleteListener(new OnCompleteListener<Void>() {
                                    @Override
                                    public void onComplete(@NonNull Task<Void> task) {




                    if(task.isSuccessful())

                                    {
                                            Toast.makeText(Register.this, "User has been registered", Toast.LENGTH_LONG).show();
                                            startActivity(new Intent(Register.this,Login.class));

                                    } else

                                    {
                                            Toast.makeText(Register.this, "Failed to register", Toast.LENGTH_LONG).show();
                                    }
                            };
            });
                    }


  }
  });

    }
}

好吧，事实证明，我在编写代码时完全失败了。事实证明，我的用户课程与我的构造者一起，在那里我的字符串两次导致数据库不知道该使用什么。
