It looks like you are encountering an issue with reassigning variables in your Android Studio project. Specifically, you mentioned that after signing up, the data is being sent to Firebase correctly but when you try to log in, the "Costumer" reference is not being recognized.

In your code snippet, I noticed a couple of potential issues that might be causing the problem:

1. Typo in DatabaseReference Names:
- You have a typo in the database references. You are using "Costumer" instead of "Customer" for the reference.
- Update the reference assignment for the customer to reference = database.getReference("Customer"); instead of reference = database.getReference("Costumer");.

2. Variable Scope Issue:
- The issue might be related to the scope of the reference variable. It seems that you are reassigning the reference variable inside the click listener based on the user type (Owner or Customer).
- Ensure that the reference variable is declared at the class level, so it can be accessed and updated within the click listener.

To address the issue, you can make the following modifications to your code:

public class SignUp extends AppCompatActivity {

    EditText signupEmail, signupPassword, signupUsername, signupPhoneNumber;
    RadioButton owner, customer;
    Button signupButton;
    TextView signupText;

    FirebaseDatabase database;
    DatabaseReference reference;

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

        signupEmail = findViewById(R.id.signupEmail);
        signupPassword = findViewById(R.id.signupPassword);
        signupUsername = findViewById(R.id.signupUsername);
        signupPhoneNumber = findViewById(R.id.signupPhoneNumber);
        signupButton = findViewById(R.id.signupButton);
        signupText = findViewById(R.id.signupText);
        owner = findViewById(R.id.owner);
        customer = findViewById(R.id.costumer);

        database = FirebaseDatabase.getInstance();
        reference = database.getReference(); // Initialize reference

        signupButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String email = signupEmail.getText().toString();
                String password = signupPassword.getText().toString();
                String username = signupUsername.getText().toString();
                String phoneNumber = signupPhoneNumber.getText().toString();
                String user = "";

                if (owner.isChecked()) {
                    user = "Owner";
                    reference = database.getReference("Owner");
                } else if (customer.isChecked()) {
                    user = "Customer";
                    reference = database.getReference("Customer");
                } else {
                    Toast.makeText(SignUp.this, "Please select a user type", Toast.LENGTH_SHORT).show();
                    return;
                }

                if (email.isEmpty() || password.isEmpty() || username.isEmpty() || phoneNumber.isEmpty()) {
                    Toast.makeText(SignUp.this, "Please fill in all fields", Toast.LENGTH_SHORT).show();
                    return;
                }

                HelperClass helperClass = new HelperClass(email, password, username, phoneNumber, user);
                reference.child(username).setValue(helperClass);

                Toast.makeText(SignUp.this, "Account Created", Toast.LENGTH_SHORT).show();
                Intent intent = new Intent(SignUp.this, LogIn.class);
                startActivity(intent);
            }
        });

        signupText.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(SignUp.this, LogIn.class);
                startActivity(intent);
            }
        });
    }
}

By making these changes, you should be able to address the issues with reassigning the reference variable and ensure that the correct reference is used when storing the data for Customers in Firebase.
