I expect to go on HomeActivity but it goes to RegisterActivity

The LoginActivity seems fine but when I test the app and try to login with the correct credentials instead to go on HomeActivity (that is the activity I need after the login) my screens goes to RegisterActivity.

On the code just at the end i put

Intent intent = new Intent(LoginActivity.this, HomeActivity.class);
                                    startActivity(intent);
                                    finish();

to me means the app should move from LoginActivity to HomeActivity

Below is the full code of LoginActivity
