Android HTTP POST Response JSON

Прошу строго не судить начинающий программист по java android. Отправляю на сервер cURL запрос. Как правильно присвоить полученные response к TextView

public static void gsonResponse() throws Exception
{
    URL url = new URL("https://fleet-api.taxi.yandex.net/v1/parks/driver-profiles/list");
    HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();
    httpConn.setRequestMethod("POST");

    httpConn.setRequestProperty("X-Client-ID", "******");
    httpConn.setRequestProperty("X-Api-Key", "******");
    httpConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

    httpConn.setDoOutput(true);
    OutputStreamWriter writer = new OutputStreamWriter(httpConn.getOutputStream());
    writer.write("{\n    \"query\": {\n        \"park\": {\n            \"id\": \"******\"\n        }\n    }\n}");
    writer.flush();
    writer.close();
    httpConn.getOutputStream().close();

    InputStream responseStream = httpConn.getResponseCode() / 100 == 2
            ? httpConn.getInputStream()
            : httpConn.getErrorStream();
    Scanner s = new Scanner(responseStream).useDelimiter("\\A");
    String response = s.hasNext() ? s.next() : "";
    System.out.println(response);
    Log.d("TEXT", response);

}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    com.ixlas.linearlayout.databinding.FragmentHomeBinding binding = FragmentHomeBinding.inflate(inflater, container, false);
    View root = binding.getRoot();

    TextView textView = binding.txtHome;
    textView.setText("Bla Bla Bla");

    try {
        HomeFragment.gsonResponse();
    } catch (Exception e) {
        e.printStackTrace();
    }

    return root;
}

Logcat тоже пустой ничего не отображает. Помогите пожалуйста
