        "maxFavoritesCount": 11
      }
    }
  ]
}

The thing is that I need only a certain part, deeper child's of this JsonObject.

What I need are basically information from resultData variable - vendorId, vendorName, shortDescription, imageURL, vendorURL.

resultData is an array of JsonObjects, so I need to iterate through them and make a list of my own objects.

What would be the way to do so?

edit -

tried the following solution -

private void getVendorsList(JsonObject body) {
        JsonArray dataArray = body.getAsJsonArray("data");
        Gson gson = new Gson();
        JSONArray jsonArray = gson.fromJson(dataArray, JSONArray.class);
        List<VendorModel> vendorModelList = new ArrayList<>();
        for (int i = 0; i < jsonArray.length(); i++) {
            try {
                JSONObject resultData = jsonArray.getJSONObject(i).getJSONObject("resultData");
                int id = resultData.getInt("id");
                String vendorName = resultData.getString("vendorName");
                String shortDescription = resultData.getString("shortDescription");
                String imageUrl = resultData.getString("imageUrl");
                String url = resultData.getString("url");
                VendorModel vendorModel = new VendorModel(id,vendorName, shortDescription, imageUrl, url);
                vendorModelList.add(vendorModel);
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
        Log.d("vendorsList", String.valueOf(vendorModelList));
    }

But I got the following error -

java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at path $

What am I missing? data is actually an array and not an object

@AlonShlider i checked, can you please try the answer above as it it? I tested it. — Helton Malambane, Nov 12 '19 at 09:13
I have tried your solution, the issue is that I am getting JsonArray (from Gson library) and not JSONArray array (from Java library). How can I cast one to another? — Alon Shlider, Nov 12 '19 at 09:26
when trying to cast it from gson.fromJson() I am getting the error - `Expected BEGIN_OBJECT but was BEGIN_ARRAY at path $` — Alon Shlider, Nov 12 '19 at 09:27
@AlonShlider please see updated solution for JsonObject instead of JSONObject — Helton Malambane, Nov 12 '19 at 10:09

Iterate through resultData and parse.

private void getVendorsList(JsonObject body) {
    JsonArray jsonArray = body.getAsJsonArray("data");
    List<VendorModel> vendorModelList = new ArrayList<>();
    if(jsonArray != null) {
        for (int i = 0; i < jsonArray.size(); i++) {
            JsonObject dataObject = jsonArray.get(i).getAsJsonObject();
            if(dataObject != null) {
                JsonObject resultObject = dataObject.getAsJsonObject("resultData");
                if(resultObject != null) {

                    //Manual parse
                    int id = resultObject.get("id").getAsInt();
                    String vendorName = resultObject.get("vendorName").getAsString();
                    String shortDescription = resultObject.get("shortDescription").getAsString();
                    String imageUrl = resultObject.get("imageUrl").getAsString();
                    String url = resultObject.get("url").getAsString();

                    VendorModel vendorModel = new VendorModel(id,vendorName, shortDescription, imageUrl, url);
                    vendorModelList.add(vendorModel);

                    //Parse using Gson. Also try this instead of above if your json key and model property are aligned
                    /*VendorModel vendorModel = new Gson().fromJson(resultObject, VendorModel.class);
                    vendorModelList.add(vendorModel);*/
                }
            }
        }
    }

    Log.d("vendorsList", String.valueOf(vendorModelList));
}

N.B: You are mixing org.json with google.gson in your implementation.

You should try this code

private void getVendorsList(JSONObject body) {

    try {
        JSONArray dataArray = body.getJSONArray("data");

        List<VendorModel> vendorModelList = new ArrayList<>();

        for (int i = 0; i < dataArray.length(); i++) {
            try {
                JSONObject resultData = dataArray.getJSONObject(i).getJSONObject("resultData");
                int id = resultData.getInt("id");
                String vendorName = resultData.getString("vendorName");
                String shortDescription = resultData.getString("shortDescription");
                String imageUrl = resultData.getString("imageUrl");
                String url = resultData.getString("url");
                VendorModel vendorModel = new VendorModel(id, vendorName, shortDescription, imageUrl, url);
                vendorModelList.add(vendorModel);
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }
}

Iterating through JSONObject and getting it's deeper childs child values
