Вылетает приложение при попытке зарегистрировать пользователя

Question

На странице приложения с регистрацией по нажатию кнопки код должен добавлять пользователя в БД, попутно выдавая сообщение. Вместо этого приложение вылетает, но по неопытности я не могу понять в чем проблема прочитав LogCat.

Код страницы -

public class AuthAndReg extends AppCompatActivity {
private EditText EdTextPassword, edName;
private FirebaseAuth mAuth;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_auth_and_reg);
    init();
}

@Override
protected void onStart() {
    super.onStart();
    super.onStart();
    FirebaseUser cUser = mAuth.getCurrentUser();

}

private void init()
{
    edName  = findViewById(R.id.edNameUser);
    EdTextPassword = findViewById(R.id.edTextPassword);
    mAuth = FirebaseAuth.getInstance();
}


public void onClickAuth(View view){
    Intent intent = new Intent(this, AuthUser.class);
    startActivity(intent);

}



public void onClickReg(View view){
    if(!TextUtils.isEmpty(edName.getText().toString()) &amp;&amp; !TextUtils.isEmpty(EdTextPassword.getText().toString()))
    {
        mAuth.createUserWithEmailAndPassword (edName.getText().toString(),EdTextPassword.getText().toString()).addOnCompleteListener(new OnCompleteListener&lt;AuthResult&gt;() {
            @Override
            public void onComplete(@NonNull Task&lt;AuthResult&gt; task) {
                if(task.isSuccessful())
                {
                    Toast.makeText(AuthAndReg.this, &quot;Добро пожаловать,&quot; + edName, Toast.LENGTH_SHORT).show();
                }
                else
                {
                    Toast.makeText(AuthAndReg.this, &quot;Что-то пошло не так&quot; , Toast.LENGTH_SHORT).show();
                }

            }
        });


    }

    else
    {
        Toast.makeText(AuthAndReg.this, &quot;Пожалуйста, заполните все поля&quot; , Toast.LENGTH_SHORT).show();
    }




}

Ищите какой из объектов в методе onClickReg не проинициализирован — Nowhere Man, Jun 24 '22 at 22:28
Возможный дубликат вопроса: Что такое stack trace, и как с его помощью находить ошибки при разработке приложений? — Nowhere Man, Jun 24 '22 at 22:28
Проверяйте разметку. Ошибка говорит что у вас в activity_auth_and_reg.xml не найден элемент с id edNameUser или edTextPassword, поэтому ссылка на один или оба равна null. — woesss, Jun 25 '22 at 04:02
