Обновление профиля с помощью модернизации

Question

я работаю над проектом Laravel & Android. Я уже сделал api с laravel и определил свой маршрут обновления и хорошо работаю с почтальоном. Route::put('/users/{id}','Api\UserController@update'); функция обновления

public function update (Request $req, $id)
{

  try {
        $user=User::find($id);
        $user->name= $req->name;
        $user->prenom= $req->prenom;
        $user->adresse= $req->adresse;
        $user->email= $req->email;
        $user->numtel= $req->numtel;

        $user->save();
           return response()->json([
        'status' => 'success',
        'data' => $user
      ]); 

      } catch (Exception $e) {

      return response()->json([
        'status' => 'error',
        'data' => 'error'
      ]); 

      }
}

В Android Studio я создаю интерфейс

    String UPDPRO ="http://IP/PFE/public/api/";
    @FormUrlEncoded
    @PUT("users/{id}")
    Call<String> UpdateUsers(
            @Path("id") int id,
            @Field("name") String name,
            @Field("prenom") String prenom,
            @Field("email") String email,
            @Field("numtel") String numtel
    );
}

и фрагмент профиля

public class Profile_Fragment extends Fragment  implements View.OnClickListener {
    private Button buttonupdate;
    private EditText editTextName, editTextEmail, editTextPrenom, editTextTel;
    private static View view;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.profile_fragment, container, false);
    }

    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        editTextName = (EditText) view.findViewById(R.id.editTextName);
        editTextEmail = (EditText) view.findViewById(R.id.editTextEmail);
        editTextPrenom = (EditText) view.findViewById(R.id.editTextPrenom);
        editTextTel = (EditText) view.findViewById(R.id.editTextTel);
        view.findViewById(R.id.buttonupdate).setOnClickListener(this);
    }
    private void updateUsers() {
        String name = editTextName.getText().toString().trim();
        String email = editTextEmail.getText().toString().trim();
        String prenom = editTextPrenom.getText().toString().trim();
        String numtel = editTextTel.getText().toString().trim();
        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(UpdateProfile.UPDPRO)
                .addConverterFactory(ScalarsConverterFactory.create())
                .build();
        UpdateProfile api = retrofit.create(UpdateProfile.class);
        Call<String> call = api.UpdateUsers(getId(), name, email, prenom, numtel);
        call.enqueue(new Callback<String>() {
            @Override
            public void onResponse(Call<String> call, Response<String> response) {

                if (response.isSuccessful()) {
                    if (response.body() != null) {
                        Log.i("Responsestring", response.body().toString());
                        Log.i("onSuccess", response.body().toString());

                        String jsonresponse = response.body().toString();

                        try {
                            JSONObject jsonObject = new JSONObject(jsonresponse);

                            if (jsonObject.getString("status").equals("success")) {
                                Toast.makeText(getActivity(), "Update Successfully!", Toast.LENGTH_SHORT)
                                        .show();
                            } else if (jsonObject.getString("status").equals("error")) {
                              /*  new CustomToast().Show_Toast(getActivity(), view,
                                        " " + jsonObject.getString("message"));*/
                                Toast.makeText(getActivity(), "Update failed!", Toast.LENGTH_SHORT)
                                        .show();
                            }
                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                }
            }

            @Override
            public void onFailure(Call<String> call, Throwable t) {
                Toast.makeText(getContext(), "Server invalid \n" + t.getMessage(), Toast.LENGTH_LONG).show();
            }
        });
    }

    @Override
    public void onClick(View view) {
        if (view == buttonupdate) {
            updateUsers();
        }
    }
}
