Converting XML to JSON in Android gives Error

I am trying to fetch the data from Earthquake API.

I am using retrofit. The data is in XML format. I am getting the data fine in XML. I am converting it in JSON using a XML-JSON Converter Library. And the library works just fine when i tried it with a simple xml string such as

<title>Hello</title>.

And the library really converts it in JSON.

But while converting the data fetched from the api, it gives me this error:

java.lang.NoSuchMethodError: No virtual method end()Z in class Lorg/json/XMLTokener

Definitely there's something with this xml. Please checkout the API response first.

These are my files: MainActivity.Java

public class MainActivity extends AppCompatActivity {

  private static final String TAG = "sagar";
  private ApiInterface apiInterface;

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

    apiInterface = ApiClient.getClient().create(ApiInterface.class);

    apiInterface.getTodos().enqueue(new Callback < ResponseBody > () {
      @Override
      public void onResponse(Call < ResponseBody > call, Response < ResponseBody > response) {
        try {
          String xmlStr = response.body().string();
          System.out.println("Response is => " + xmlStr.trim());
          JSONObject jsonObject = XML.toJSONObject(xmlStr);
          System.out.println("Response -> " + jsonObject);

        } catch (JSONException | IOException e) {
          e.printStackTrace();
        }
        //                System.out.println("Response -> " + response.body());
      }

      @Override
      public void onFailure(Call < ResponseBody > call, Throwable t) {
        System.out.println("Failure -> " + t.getMessage());

      }
    });
  }
}

APIClient.java

public class ApiClient {

  private static final String BASE_URL = "https://earthquake.usgs.gov/";
  private static Retrofit retrofit = null;

  public static Retrofit getClient() {
    if (retrofit == null) {
      retrofit = new Retrofit.Builder()
        .baseUrl(BASE_URL)
        .addConverterFactory(GsonConverterFactory.create())
        .build();
    }
    return retrofit;
  }

}

ApiInterface.java

public interface ApiInterface {

  @GET("earthquakes/feed/v1.0/summary/significant_day.atom")
  Call < ResponseBody > getTodos();

}

Just replace .atom in the url with .geojson

https://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/significant_day.geojson

Output:
