            } catch (IOException e) {
                e.printStackTrace();
            }
            return fbDoc;

        protected void onPostExecute(Document document) {
            try {
                String videoUrl = document.select("meta[property=\"og:video\"]")
                        .last().attr("content");
                if(!videoUrl.equals(""))
                    Util.download(videoUrl, Util.RootDirectoryFacebook, activity, "facebook" + System.currentTimeMillis() + ".mp4");
            } catch (Exception e) {
                e.printStackTrace();
                Toast.makeText(activity, R.string.url_is_invalid, Toast.LENGTH_SHORT).show();
            }
