Answer 1

The given url returns a JSONArray, so the method getJSONFromUrl should return JSONArray..

try {
        HttpParams params = new BasicHttpParams();
        HttpConnectionParams.setConnectionTimeout(params, Constants.CONNECTION_TIME_OUT);
        HttpConnectionParams.setSoTimeout(params, 0);
        HttpClient httpClient = new DefaultHttpClient(params);

        //prepare the HTTP GET call 
        HttpGet httpget = new HttpGet(urlString);
        //get the response entity
        HttpEntity entity = httpClient.execute(httpget).getEntity();

        if (entity != null) {
            //get the response content as a string
            String response = EntityUtils.toString(entity);
            //consume the entity
            entity.consumeContent();

            // When HttpClient instance is no longer needed, shut down the connection manager to ensure immediate deallocation of all system resources
            httpClient.getConnectionManager().shutdown();

            //return the JSON response
            JSONArray array = new JSONArray(response.trim());
                for(int i = 0 ; i < array.length() ; i++) { //get the current JSON object
                    JSONObject object = (JSONObject) array.get(i);
                    String vehicleType = object.getString("vehicleType");
                    ......
                 }
        }
    }catch (Exception e) {
        e.printStackTrace();
    }
