How to use Jsoup with Volley?

Question

I have a working example with Jsoup and AsyncTask, and that works fine. I am just not satisfied with the performance. It takes 3-6 seconds to load a simple list page with te

With Stephan`s answer I have made some little modifications to this code and it looks like this. I have added UTF 8 support so it can read other languages and specified the retry policy.

private static RequestQueue myRequestQueue = null;

public Document GetDocument(String site) {
    final Document[] doc = new Document[1];
    final CountDownLatch cdl = new CountDownLatch(1);
    try {

        StringRequest documentRequest = new StringRequest( //
                Request.Method.GET, //
                site, //
                new Response.Listener() {
                    @Override
                    public void onResponse(String response) {
                        String newStr = null;
                        try {
                            newStr = URLDecoder.decode(URLEncoder.encode(response, "iso8859-1"), "UTF-8");
                        } catch (UnsupportedEncodingException e) {
                            e.printStackTrace();
                        }
                        doc[0] = Jsoup.parse(newStr);
                        cdl.countDown();
                    }
                }, //
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        // Error handling
                        System.out.println("Houston we have a problem ... !");
                        error.printStackTrace();
                    }
                } //
        );

        if (myRequestQueue == null) {
            myRequestQueue = Volley.newRequestQueue(MainActivity._Instance);

            documentRequest.setRetryPolicy(new DefaultRetryPolicy(5000,
                    DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
                    DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
        }

        // Add the request to the queue...
        myRequestQueue.add(documentRequest);

        // ... and wait for the document.
        // NOTA: Be aware of user experience here. We don't want to freeze the app...
        cdl.await();
    }
    catch (Exception e) {
        Log.d("TMS", "Error parsing page " + site);
        e.printStackTrace();
        return null;
    }
    return doc[0];
}
