            JSONObject objJson = jsonArray.getJSONObject(i);

            TopTenGetterSetter obj = new TopTenGetterSetter();  


            obj.setQ(objJson.getString("question"));
            obj.setA(objJson.getString("option1"));
            obj.setB(objJson.getString("option2"));
            obj.setC(objJson.getString("option3"));
            obj.setD(objJson.getString("option4"));

Answer 1

org.json.JSONException: Value response of type java.lang.String cannot be converted to JSONArray

Looks like response is a string not a json array

{  // json object node 
    "response": { // json object response
        "result": 1,
        "Message": [ // json array Message
            {        // json object node 
                "pollid": "98",
                 "category": "Entertainment",
                 "question": "what",  //  string
                 "option1": "981.mov",

The result is a json object not json array

JSONArray jsonArray = new JSONArray(result);

Should be

JSONObject jObj = new JSONObject(result);
JSONObject response = jObj.getJSONObject("response");
//JSONObject jb = new JSONObject(response);
JSONArray jr = response.getJSONArray("Message");
for(int i=0;i<jr.length();i++)
{
JSONObject jb1 = jr.getJSONObject(i);
String question = jb1.getString("question");
Log.i(".......",question);
}
