Handle HTTP status code errors

[inghamn]

During GET and POST, the endpoints may spit ouu various HTTP status codes as error messages. Right now, we do not have any status code error checking. We need to add checks for status code errors during Open311.loadStringFromUrl and Open311.postServiceRequest

I need to figure out how best to trap various types of exceptions that can happen and display different Dialog messages. Also, depending on the type of exception, we may want to not display any Dialog message to the user.. we may just want to do something instead.

public static String loadStringFromUrl(String url)
        throws ClientProtocolException, IOException, IllegalStateException, HttpResponseException {
    ResponseHandler<String> handler = new BasicResponseHandler();
    return getClient().execute(new HttpGet(url), handler);
}

Updated POST Service Request to handle HTTP Status Codes by sending a new Open311Exception with custom errorMessage.

POST is doing it right. Now, we just need to take a look at GET Service List, GET Service Definition calls.
