почему пример на видео работает а у меня возникает ошибка

учусь писать код по видео курсу, в видео все работает, а у меня выходит ошибка.

JSONObject jsonObject = new JSONObject(s); JSONArray jsonArray = new jsonObject.getJSONArray(s); //Cannot resolve symbol 'getJSONArray'

public class MainActivity extends AppCompatActivity {
private ListView lv;
String article, date;

//JSON string
private static String JSON_URL = "https://cms.zaonce.net/en-GB/jsonapi/node/galnet_article?sort=-created";

    getData.execute();
