Can't get correct response from API

Hi, I'm trying to do this app but I'm stock because I dont receive a json array as a response. I am using the location that it's being used in the videos, which is also the example that is used in the documentation of the forecast API. Instead I'm receiving the following string: "com.squareup.okhttp.internal.http.RealResponseBody@d0c4f9b". Does anybody know why?

paste the code where you have used JSONArray to create an array object of type JSONArray

This is the code, it's basicly the one made in the videos. The part where I'm receiving the string instead of the JSON array it's on the on response method of the callback function.

public class MainActivity extends AppCompatActivity {

    public static final String TAG = MainActivity.class.getSimpleName();

    private CurrentWeather mCurrentWeather;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        String apiKey ="731df217cbd579c1bed946fd0168a114";
        double latitude=37.8267;
        double longitude=-122.423;
        String forecastURL="http://api.forecast.io/forecast/731df217cbd579c1bed946fd0168a114/37.8267,-122.423";
        if (isNetworkAvailable()) {
            OkHttpClient client = new OkHttpClient();
            Request request = new Request.Builder().url(forecastURL).build();
            Call call = client.newCall(request);
            call.enqueue(new Callback() {
                @Override
                public void onFailure(Request request, IOException e) {

                    Log.i(TAG, "on failure");
                }

                @Override
                public void onResponse(Response response) throws IOException {
                    try {
                        String jsonData = response.body().toString();
                        Log.v(TAG, jsonData);
                        if (response.isSuccessful()) {
                            mCurrentWeather = getCurrentDetails(jsonData);

                        } else {
                            alertUserAboutError();
                        }
                    } catch (JSONException e){
                        Log.e(TAG, "Exception caught", e);
                    }
                }
            });
        } else {
            Toast.makeText(this, R.string.network_unavailable_message, Toast.LENGTH_LONG).show();
        }
        Log.d(TAG, "Main UI code is running");
    }

    private CurrentWeather getCurrentDetails(String jsonData) throws JSONException{
        JSONObject forecast = new JSONObject(jsonData);
        String timezone = forecast.getString("timezone");
        Log.i(TAG, "From JSON "+timezone);
        JSONObject currently = forecast.getJSONObject("currently");
        CurrentWeather currentWeather= new CurrentWeather();
        currentWeather.setmHuidity(currently.getDouble("humidity"));
        currentWeather.setmTime(currently.getLong("time"));
        currentWeather.setmIcon(currently.getString("icon"));
        currentWeather.setmPrecipChance(currently.getDouble("precipProbability"));
        currentWeather.setmSummary(currently.getString("summary"));
        currentWeather.setmTemperature(currently.getDouble("temperature"));
        return currentWeather;
    }

    private boolean isNetworkAvailable() {
        ConnectivityManager manager= (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = manager.getActiveNetworkInfo();
        boolean isAvailable = false;
        if (networkInfo!=null && networkInfo.isConnected()){
            isAvailable=true;
        }
        return isAvailable;
    }
    private void alertUserAboutError() {
        AlertDialogFragment dialog = new AlertDialogFragment();
        dialog.show(getFragmentManager(), "error_dialog");
    }
}

I found my mistake in the following line of code:

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

Should be this:

String jsonData = response.body().string();
