How to solve JSONArray problem, cant get data, Android Studio

Question

I'm having some issues with JSON in Android Studio I've been watching and reading about some examples, but still can't figure out how to pass those data from database into "Movie" class, as its shown in Java code.

Here is the log where error begins, and its shown that he is reading server and getting data in log on the first line.

private void getMoviesFromDB(int id) {

    AsyncTask<Integer, Void, Void> asyncTask = new AsyncTask<Integer, Void, Void>() {
        @org.jetbrains.annotations.Nullable
        @Override
        protected Void doInBackground(Integer... movieIds) {

            OkHttpClient client = new OkHttpClient();
            Request request = new Request.Builder()
                    .url("http://192.168.8.101/databaseproject/getMenu.php?category=" + category)
                    .build();
            try {
                Response response = client.newCall(request).execute();
                Log.d(TAG, "response: " + response.body().string());
                JSONArray array = new JSONArray(response.body().string());

                for (int i = 0; i < array.length(); i++) {

                    JSONObject object = array.getJSONObject(i);

                    Movie movie = new Movie(object.getInt("food_id"), object.getString("food_title"),
                            object.getString("food_image"), object.getString("food_description"), object.getString("food_price"));

                    MainActivity.this.movies.add(movie);
                }


            } catch (IOException e) {
                e.printStackTrace();
            } catch (JSONException e) {
                e.printStackTrace();
            }
            return null;
        }

Log says that error is at MainActivity at line 139 and 127

139: JSONArray array = new JSONArray(response.body().string());

127: AsyncTask asyncTask = new AsyncTask() { ...

D/MILJ: response: [{"food_id":"2","food_title":"indeks","food_image":"http://indexhouse.rs/wp-content/uploads/2014/12/sendvic-prsuta.jpg","food_description":"sendvic","food_price":"200","food_category":"snacks"}]

Can someone please help me?I don't understand how to solve this JSON particular case...

Thanks in advance.

You probably want to put the response into a String instead of JSONArray, then create a JSONObject with that String and go from there.

Can you paste the JSON?
