To take another array in an object you have to change

JSONArray jArray1 = jArray.getJSONArray(i);

to

JSONArray jArray1 = jsonObject1.getJSONArray("discounts");

In your json response "product" is not json array it is json object. Change like this in your doInBackground().

    protected Boolean doInBackground(String... param){
    try {

        HttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost(param[0]);
        HttpResponse response = client.execute(post);

        int status = response.getStatusLine().getStatusCode();
        if(status == 200){
            HttpEntity entity = response.getEntity();
            String data = EntityUtils.toString(entity);

            JSONObject jsonObject = new JSONObject(data);


                JSONObject jsonObject1 = jsonObject.getJSONObject("product");

                Products products = new Products();

                products.setId(jsonObject1.getString("id"));
                products.setName(jsonObject1.getString("name"));
                products.setManufacturer(jsonObject1.getString("manufacturer"));
                products.setModel(jsonObject1.getString("model"));
                products.setReward(jsonObject1.getString("reward"));
                products.setPoints(jsonObject1.getString("points"));
                products.setImage(jsonObject1.getString("image"));
                products.setPrice(jsonObject1.getString("price"));
                products.setSpecial(jsonObject1.getString("special"));



                JSONArray jArray1 = jsonObject1.getJSONArray("discounts");

                for(int j = 0;j<jArray1.length();j++){

                    JSONObject jsonObject2 = jArray1.getJSONObject(j);

                    products.setDiscounts_quantity(jsonObject2.getString("quantity"));
                    products.setDiscounts_price(jsonObject2.getString("price"));
                }
                JSONArray jArray2 = jsonObject1.getJSONArray("options");

                for(int j = 0;j<jArray2.length();j++){

                    JSONObject jsonObject2 = jArray2.getJSONObject(j);

                    products.setOptions_product_option_id(jsonObject2.getString("product_option_value_id"));
                    products.setOptions_option_id(jsonObject2.getString("option_id"));
                    products.setOptions_name(jsonObject2.getString("name"));
                    products.setOptions_type(jsonObject2.getString("type"));

                    JSONArray jsonArray3 = jsonObject2.getJSONArray("option_value");

                    for(int k = 0;k < jsonArray3.length();k++){

                        JSONObject jsonObject3 = jsonArray3.getJSONObject(k);

                        products.setOptions_option_value_product_option_value_id(jsonObject3.getString("product_option_value_id"));
                        products.setOptions_option_value_option_value_id(jsonObject3.getString("option_value_id"));

                    }

                        products.setOptions_required(jsonObject2.getString("required"));
                }

                        products.setMinimum(jsonObject1.getString("minimum"));

                        products.setDescription(jsonObject1.getString("description"));

                        JSONArray jsonArray = jsonObject1.getJSONArray("attribute_groups");

                        for(int j = 0; j < jsonArray.length();j++){

                productsList.add(products);

JSONObject jsonObject1 = jArray.getJSONObject("product"); This jArray?? — Anand Jain, Commented Sep 21, 2015 at 10:57
That's my mistake changed jArray to jsonObject. Edited answer. — Ved, Commented Sep 21, 2015 at 11:21
When i am trying your code its give a error JSONObject cannot be converted to JSONArray. — Anand Jain, Commented Sep 21, 2015 at 12:24

Json will just parse the json file in to one json object and then you can just reference it.
