You can do something very simply like this.

try {
                    ArrayList<String> _pics = new ArrayList<String>();
                    JSONObject _jObject = new JSONObject("YOUR_JSON_STRING");
                    JSONArray _picArr  = _jObject.getJSONArray("picurl");
                    for (int i = 0; i < _picArr.length(); i++) {

                        String _picPath  = _picArr.getString(i);
                        _pics.add(_picPath);

                    }
                } catch (JSONException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

Step 1: Convert your response into JSONObject

Step 2: Pass picurl JSONArray to Gson.

Type type = type = new TypeToken<List<Model>>() {}.getType();
Gson objGson = new Gson();
JSONObject response = new JSONObject(responseString);
List<Model> result = objGson.fromJson(response .getJSONArray("picurl").toString(), type);
