parse json:

JSONObject jsonObj = new JSONObject(jsonStr);// your string.
JSONArray jsonArray = jsonObj.getJSONArray("products");


for(int i=0; i < jsonArray.length(); i++){
       JSONObject prod = jsonArray.getJSONObject(i);
       String id = prod.getString("id");

       // and so on ...you can parse the entire json using either array or object

}

surround with try catch for exception....

First you need to verif y if your JSON is valid or not. Json Validator

if you find this valid then `

try { JSONObject  jsonRootObject = new JSONObject(strJson);
         //Get the instance of JSONArray that contains JSONObjects
         JSONArray jsonArray = jsonRootObject.optJSONArray("products");   
         //Iterate the jsonArray and print the info of JSONObjects
         for(int i=0; i < jsonArray.length(); i++){
            JSONObject jsonObject = jsonArray.getJSONObject(i);
            int id = Integer.parseInt(jsonObject.optString("id").toString());
            String name = jsonObject.optString("name").toString();
            float product_image = Float.parseFloat(jsonObject.optString("product_image").toString());
         JSONArray cat_idArray = jsonRootObject.optJSONArray("cat_id");    
         for(int i=0; i < cat_idArray.length(); i++){
        //Here you can get other values
           }
            data += "Node"+i+" : \n id= "+ id +" \n Name= "+ name +" \n Salary= "+ salary +" \n ";
         }
         output.setText(data);
      } catch (JSONException e) {e.printStackTrace();}

` Also there are lots of example in web where you can learn. like this one
