I'm learning REST using Retrofit to register and login on an API in swaggerhub but i'm unable to do it, and it is not showing any error message in my studio. I have google REST AUTHENTICATRION but non of the link was helpful. I have also looked here and here but still couldn't figure it out.

HERE IS MY SignUpActivity

public class SignUpActivity extends AppCompatActivity implements View.OnClickListener 
private EditText mPassword;
private EditText mPassword2;
private String password;


private CountryCodePicker ccp;

private ProgressDialog pDialog;
private ProgressBar progressBar;


LoginServices loginService;
@Override
protected void onCreate(Bundle savedInstanceState) 
 super.onCreate(savedInstanceState);
 setContentView(R.layout.sign_up_activity);




 findViewById(R.id.sign_up_button).setOnClickListener(this);

 mPassword = findViewById(R.id.password);
 mPassword2 = findViewById(R.id.password2);

 progressBar = findViewById(R.id.login_progress);

 loginService = ServiceGenerator.createService(LoginServices.class,
 getApplication(), USER_BASE_URL);


 ccp = findViewById(R.id.ccp);
 EditText mUsername = findViewById(R.id.username);
 ccp.registerCarrierNumberEditText(mUsername);




private boolean validateForm() 

 boolean valid = true;
 View focusView = null;

 password = mPassword.getText().toString();
 // String conPassword = mConfirmPasswordView.getText().toString();
 if (!TextUtils.isEmpty(password) && !isPasswordValid(password)) 
 mPassword.setError(getString(R.string.error_invalid_password));
 focusView = mPassword;
 valid = false;
 else 
 mPassword.setError(null);
 

 if (!valid) 
 // There was an error; don't attempt login and focus the first
 // form field with an error.
 focusView.requestFocus();
 
 return valid;


private boolean isPasswordValid(String password) 
 String password2 = mPassword2.getText().toString();
 // Add regex for at least 8 characters including lower case, upper case, digit and special character
 return password.equals(password2) && password.length() >= 6;



private void submitUserDetails( String email, String password)

 startUi();

 Call<Message> call = loginService.createUser(email, password);

 call.enqueue(new Callback<Message>() 
 @Override
 public void onResponse(Call<Message> call, Response<Message> response) 
 if (response.isSuccessful())
 // hidepDialog();
 stopUi();
 if (response.body() != null)
 Message message = response.body();
 String regMessage = message.getEmail();
 Log.d("GET INFORMATION: ", call.toString());
 Log.d("GET MESSAGE: ", message.toString());

 Toast.makeText(getApplicationContext(), regMessage + "registered successfully", Toast.LENGTH_SHORT)
 .show();

 finish();

 
 else
