your json format is not correct try like that;

{"question":
{"question_id": "13", 
 "name": "certain degrees", 
 "tags": [{"android":"N", "sensor":"Y"}]
 }}

You can use http://jsonviewer.stack.hu/, to be sure correction of your json data

I sugest you try this code,

import org.json.JSONArray;
import org.json.JSONObject;

public class Main {

    public static void main(String[] args) {
        String text = "[  { \"question_id\": 13, \"creation_date\": 10, \"name\": \"certain degrees\", \"tags\": [ \"android\", \"sensor\" ] } ]";

        System.out.println(text);

        JSONArray jsonArray = new JSONArray(text);

        JSONObject jsonObjetc = jsonArray.getJSONObject(0);

        JSONArray tagarray = jsonObjetc.getJSONArray("tags");

        System.out.println(tagarray);

        for(int j=0;j<tagarray.length();j++){
            System.out.println(tagarray.getString(j));
        }
    }
}

Good luck, Aron

Try this,

   ArrayList<String> list = new ArrayList<String>();

String text = "[  { \"question_id\": 13, \"creation_date\": 10, \"name\": \"certain degrees\", \"tags\": [ \"android\", \"sensor\" ] } ]";
  try {
        JSONArray jarray = new JSONArray(text);

        for (int i = 0; i < jarray.length(); i++) {
            JSONArray j_array = jarray.getJSONObject(i)
                    .getJSONArray("tags");

            for (int j = 0; j < j_array.length(); j++) {
                String str = j_array.getString(j);

                list.add(str);

            }

        }
    } catch (Exception e) {

    }

Try This

tagarray = questionobj.getJSONArray("tags");

    for(int j=0;j<tagarray.length();j++)
    {
        tagname.add(tagarray.getJSONObject(j).getString("android"));         
    }
