I am creating an app in which the user registers with his email and password, then the app will give the user a 4 digit PIN. The registration works in the sense that the email and password gets saved, but the 4 digit PIN isn't being generated and the registration button doesn't take me to the next activity, however if I type in the email and password in the login activity I can get to the next screen. This is my registration activity code, after the registration button is clicked.

btnRegistration = findViewById(R.id.buttonSignUp);
        mAuth = FirebaseAuth.getInstance();
        usersNodeRef = FirebaseDatabase.getInstance().getReference().child("users");

btnRegistration.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                EditText editTextEmail = findViewById(R.id.editTextRegistrationEmail);
                EditText editTextPassword = findViewById(R.id.editTextRegistrationPassword);
                EditText editTextConfirmPassword = findViewById(R.id.editTextRegistrationConfirmPassword);

String email = editTextEmail.getText().toString();
                String password = editTextPassword.getText().toString();
                String confirmPassword = editTextConfirmPassword.getText().toString();

if (password.equals(confirmPassword)) {
                    mAuth.createUserWithEmailAndPassword(email, password)
                            .addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                                @Override
                                public void onComplete(@NonNull Task<AuthResult> task) {
                                    if (task.isSuccessful()) {
                                        // User registration is successful
                                        FirebaseUser user = mAuth.getCurrentUser();
                                        String userId = user.getUid();

// Generate a PIN for the user
                                        String pin = generatePin();

// Store the PIN in the Firebase Realtime Database
                                        usersNodeRef.child(userId).child("pin").setValue(pin)
                                                .addOnCompleteListener(new OnCompleteListener<Void>() {
                                                    @Override
                                                    public void onComplete(@NonNull Task<Void> task) {
                                                        if (task.isSuccessful()) {
                                                            // PIN stored successfully
                                                            Toast.makeText(Registration.this, "Registration successful. Your PIN is: " + pin, Toast.LENGTH_SHORT).show();

// Navigate to the next screen
                                                            Intent intent = new Intent(Registration.this, UserProfile.class);
                                                            intent.putExtra("pin", pin);
                                                            startActivity(intent);
                                                            finish(); // Optional: Finish the current activity to prevent going back
                                                        } else {
                                                            // Failed to store the PIN
                                                            Toast.makeText(Registration.this, "Failed to store PIN. Please try again.", Toast.LENGTH_SHORT).show();
                                                            Log.e("Registration", "Failed to store PIN: " + task.getException().getMessage());
                                                        }
                                                    }
                                                });
                                    } else {
                                        // User registration failed
                                        // Handle the error, display a message, etc.
                                        String errorMessage = task.getException().getMessage();
                                        Toast.makeText(Registration.this, "Failed to register: " + errorMessage, Toast.LENGTH_SHORT).show();
                                        Log.e("Registration", "Failed to register: " + errorMessage);
                                    }
                                }
                            });
                } else {
                    // Password and confirm password do not match
                    Toast.makeText(Registration.this, "Password and confirm password do not match", Toast.LENGTH_SHORT).show();
                }
            }

private String generatePin() {
                // Generate a 4-digit PIN
                Random random = new Random();
                int pinNumber = random.nextInt(9000) + 1000;
                return String.valueOf(pinNumber);
            }
        });

Is the onComplete handler in line 20 ever called?

If it is, is "task.isSuccessful()" true?

Same for lines 33 and 34.

So that's 4 questions to answer in total :-)
