parsing multiple json object in jsonarray using gson

Here is an example of what the structure might look like, depending on your json results it might change slightly.

package com.example.test;

import java.util.List;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;

import com.google.gson.Gson;
import com.google.gson.annotations.SerializedName;

public class MainActivity extends Activity {

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

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

        String json = "{results:[{\"SupplierCatalog\":{\"supplier_catalog_id\": \"139\",\"distributor_id\": \"57\",\"distributor_asking_price\": \"999.99\",\"supplier_id\": null,\"product_name\": \"jjjjjjjj j j j j j j  jj j jjjjjjjjjjjj\",\"product_description\": \"kkkkkkkkkkkkkk k k  k k\"},\"image_details\": {\"isCustomImageProvided\": 0,\"isImageUploadedTo\": 1}}]}";

        JsonParseResult jsonParseResult = new Gson().fromJson(json, JsonParseResult.class);

        if (jsonParseResult != null && jsonParseResult.getResult() != null) {
            for (Result result : jsonParseResult.getResult()) {
