JSONException: Value ___ of type java.lang.String cannot be converted to JSONObject

Question

I am learning retrieving data from database or website in json format. I have written the code for parsing the data. The problem is I am getting JsonException when I put string in jsonObject constructor. I have been searching to solve this problem but seems like my code doesn't have any problems. The json data I am getting from internet also seems ok to me. I want to seek experts help here for reading this json format data. Here is my code:

JSONObject json=null;

    Toast.makeText(DisplaySubjectsInList.this, "json method", Toast.LENGTH_SHORT).show();

    String temp ="";
    temp = sb.toString();


    try 
    {
        JSONObject jsonObj = new JSONObject(temp);

        JSONArray jsonArray = jsonObj.getJSONArray("contacts");


        ListOfSubjects = new String[jsonArray.length()];

        //subjectAddresses = new String[jsonArray.length()];


        for(int i=0; i<2; i++)
        {
            json = jsonArray.getJSONObject(i);

            ListOfSubjects[i] = json.getString("name"); 
            //subjectAddresses[i]=json.getString("Adress");

            Toast.makeText(DisplaySubjectsInList.this, ListOfSubjects[i], Toast.LENGTH_SHORT).show();
        }

    } 
    catch (JSONException e) 
    {
        Toast.makeText(DisplaySubjectsInList.this, "json failed", Toast.LENGTH_SHORT).show();
        e.printStackTrace();
    }

Here is the link to json format data: Json

I have also tried non formated json but it is returning <p>Forbidden</p>

You need to encode your json without formatting it. The parser doesn't like 'beautified' json.
