Answer 1

Try use Gson lib for parse it.

dependencies {
    compile 'com.google.code.gson:gson:2.3.1'
}

You can generation pojo for parse json. (For example on this site http://www.jsonschema2pojo.org )

For parse use this.

T t = new Gson().fromJson(serverResponse.getResponse(), type);

Where 'T' is your response data, and 'type' it pojo from site.

If your type is entity use Type type = Entity.class; If your type is list of entities use

Type type = new TypeToken<List<WadadayFull>>() {
            }.getType())

try this code:

try {
            JSONArray array1 = new JSONArray(str);
            for (int i=0;i<array1.length();i++){
                JSONObject obj1 = array1.getJSONObject(i) ;
                JSONArray array2 = obj1.getJSONArray("bus_schedule");
                for (int j=0;j<array2.length();j++){
                    JSONObject obj2 = array2.getJSONObject(j);
                    JSONArray array3 = obj2.getJSONArray("bus_route");
                    ArrayList<Example1> list = new ArrayList<>();
                    for (int k=0;k<array3.length();k++) {
                        JSONObject obj3 = array3.getJSONObject(k);

                        String s1 = obj3.getString("serviceDate");
                        String s2 = obj3.getString("amenities");
                        String s3 = obj3.getString("startCityName");
                        String s4 = obj3.getString("departureTime");
                        String s5 = obj3.getString("fare");
                        String s6 = obj3.getString("endCityName");
                        String s7 = obj3.getString("arrivalTime");
                        String s8 = obj3.getString("operatorName");
                        String s9 = obj3.getString("bus_id");
                        String s10 = obj3.getString("journeyHours");
                        String s11 = obj3.getString("available_seat");
                        String s12 = obj3.getString("total_seats");
                        String s13 = obj3.getString("seat_type");

                        Example1 ex1 = new Example1();
                        ex1.setServiceDate(s1);
                        ex1.setAmenities(s2);
                        ex1.setStartCityName(s3);

                        list.add(ex1);
                        Log.e("response", list.toString());


                    }

                    JSONArray array4 = obj2.getJSONArray("boardingPoint");
                    ArrayList<Example2> list2 = new ArrayList<>();
                    for (int l = 0; l < array4.length(); l++) {
                        JSONObject obj4 = array4.getJSONObject(l);

                        String s14 = obj4.getString("boardingPointName");
                        String s15 = obj4.getString("boardingPointContact");
                        String s16 = obj4.getString("boardingPointTime");
                        String s17 = obj4.getString("boardingPointId");
                        String s18 = obj4.getString("BusId");
                        Example2 ex2 = new Example2();
                        ex2.setBoardingPointName(s14);
                        ex2.setBoardingPointContact(s15);
                        list2.add(ex2);
                        Log.e("response", list2.toString());
                    }

                }

            }

            Log.e("response",array1.toString());
        } catch (JSONException e) {
            e.printStackTrace();
        }
