JSON Parsing in Android

As I find out I need to use Gson class to parse json to Java object in android. It’s quite easy to parse simple varables or array, but I don’t know how to parse more complex json string, my json look like this:

{"selected_id":3, "data":[{"id":"3","score":"1534"},{"id":"1","score":"1234"}]}

Can anyone help me how to do this?

      //Model class 

    class Model {

         private  String mId ;
          private   String mScore;

         public Model (String id , String score){

             mId = id ;
             mScore= score
         }


      //getter and setter 

    } 

// in your class

    private ArrayLsit getLsit(String str){
      ArrayLsit<Model > list = new  ArrayLsit<Model>();

        // getting JSON string from URL
        JSONObject json = new JSONObject(str);

        try {
            // Getting Array of Contacts
            contacts = json.getJSONArray("data");

            // looping through All Contacts
            for(int i = 0; i < contacts.length(); i++){
                JSONObject c = contacts.getJSONObject(i);

                // Storing each json item in variable
                String id = c.getString("id");
                String score= c.getString("score");
                list.add(new Model(id ,score))

            }
        } catch (JSONException e) {
            e.printStackTrace();
        }

   return list

 }
