I've looked up some answers but am not sure why mine is failing exactly...

The code looks something like this

        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        String json = EntityUtils.toString(httpEntity);

        //Convert to JsonArray
        JSONArray jsonArray = new JSONArray(json);

        Log.i(DEBUG_TAG, Integer.toString(jsonArray.length()));

        for (int i = 0; i < jsonArray.length(); i++) {
            JSONObject jsonObject = jsonArray.getJSONObject(i);
            Log.i(DEBUG_TAG, jsonObject.getString(KEY_ID));

            // creating new HashMap
            HashMap<String, String> map = new HashMap<String, String>();
            // adding each child node to HashMap key => value
            map.put(KEY_ID, jsonObject.getString(KEY_ID));
            map.put(KEY_TITLE, jsonObject.getString(KEY_TITLE));
            map.put(KEY_ARTIST, jsonObject.getString(KEY_ARTIST));
            map.put(KEY_DURATION, jsonObject.getString(KEY_DURATION));
            map.put(KEY_VOTECOUNT, jsonObject.getString(KEY_VOTECOUNT));
            map.put(KEY_THUMB_URL, jsonObject.getString(KEY_THUMB_URL));
            map.put(KEY_GENRE, jsonObject.getString(KEY_GENRE));

            //Adding map to ArrayList
            if (Integer.parseInt(jsonObject.getString(KEY_VOTECOUNT)) == -1){
                //If VoteCount is -1 then add to header
                headerList.add(map);
            }else {
                songsList.add(map);
            }
        }

    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

When I run logcat on String json, it seems to show correct info which is kind of like this...

  {
"userdata": [
    {
        "id": "8",
        "title": "Baby One More Time",
        "artist": "Britney Spears",
        "duration": "03:24:00",
        "votes": "0",
        "thumb_url": "http://api.androidhive.info/music/images/dido.png",
        "genre": null
    },
    {
        "id": "2",
        "title": "As Long As You Love Me",
        "artist": "Justin Bieber",
        "duration": "05:26:00",
        "votes": "0",
        "thumb_url": "http://api.androidhive.info/music/images/enrique.png",
        "genre": "Rock"
    }
]
}

and the logcat on

JSONArray jsonArray = new JSONArray(json);

tells me that jsonArray.length()

10-31 22:57:28.433: W/CustomizedListView(26945): error! Invalid index 0, size is 0

Please let me know

Thank you,
