Following code may be wrong.
public RssRequest(int method, String url, Listener listener, ErrorListener errorListener) {
super(Method.GET, url, errorListener);
....
}

It may be better to following.
public RssRequest(int method, String url, Listener listener, ErrorListener errorListener) {
super(method, url, errorListener);
....
}
