get data from newsapi

Question

I'm trying to get news API from https://newsapi.org. on IntelliJ when I call : httpURLConnection.setRequestMethod("GET"); I get response and its working but on the androidstudio when I call the method I get this error : java.io.FileNotFoundException: https://newsapi.org

here is the full code:

`  try {
        URL url = new URL("https://newsapi.org");
        HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
        httpURLConnection.setRequestMethod("GET");
        httpURLConnection.connect();

        InputStreamReader inputStreamReader = new InputStreamReader(httpURLConnection.getInputStream());
        BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
        String s = bufferedReader.readLine();
        StringBuilder stringBuilder = new StringBuilder();

        while (s != null) {
            stringBuilder.append(s);
            s = bufferedReader.readLine();
        }

        System.out.println(stringBuilder.toString());

    } catch (IOException e) {
        e.printStackTrace();
    }  `

here is the full code :

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mA m = new mA();
    m.execute();
}

class mA extends AsyncTask<Void, Void, Void> {

    @Override
    protected Void doInBackground(Void... voids) {

        try {
            URL url = new URL("https://newsapi.org/v2/top-headlines?q=Apple&from=2022-08-31&sortBy=popularity&apiKey=648805f67bdb4aa6a454d4f6480ae35d");
            HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
            httpURLConnection.setRequestMethod("GET");
            httpURLConnection.connect();

            InputStreamReader inputStreamReader = new InputStreamReader(httpURLConnection.getInputStream());
            BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
            String s = bufferedReader.readLine();
            StringBuilder stringBuilder = new StringBuilder();

            while (s != null) {
                stringBuilder.append(s);
                s = bufferedReader.readLine();
            }

            JSONObject jsonObject = new JSONObject(stringBuilder.toString());
            JSONArray jsonArray = jsonObject.getJSONArray("articles");
            JSONObject jsonObject1 = jsonArray.getJSONObject(0);
            String sss = jsonObject1.getString("title");


            System.out.println(stringBuilder.toString());

        } catch (MalformedURLException e) {


        } catch (IOException | JSONException e) {
            e.printStackTrace();
        }


        return null;
    }
}

}

Answer 1

By calling the base URL (https://newsapi.org) with the GET method you will fetch the website content in HTML. It's just like opening the URL in your browser.

According to the Documentation, you should first get an API key to be able to send requests and fetch the news. Aside from this, you should use the correct API address mentioned here.
