i have a program where i consult google spreadsheets, i do it in a AsyncTask but is very slow so i want to put a ProgressDialog, i show it on onPreExecute method but my program can´t execute doInBackground method, howewer i can see that app enters in this method thaks to Log.i, but don´t do nothing, i can see Progress dialog but nothing else, it´s like an infinite bucle

My AsyncTask is like this:

private class GestionDatos extends AsyncTask<Void, Void, ArrayList<String>> {

    @Override
    protected void onPreExecute(){
        super.onPreExecute();


        mProgress = ProgressDialog.show(MainActivity.this, "Trabajando", "Espere por favor");
    }


    @Override
    protected ArrayList<String> doInBackground(Void... params) {
        SpreadsheetService service = new SpreadsheetService("com.banshee");
        ArrayList<String> nombres = new ArrayList<String>();
        String idAnterior = "idAnterior";
        try {

            String urlString = "My URL";

            URL url = new URL(urlString);

            ListFeed feed = service.getFeed(url, ListFeed.class);

            for (ListEntry entry : feed.getEntries()) {
                CustomElementCollection elements = entry
                        .getCustomElements();
                String id = elements.getValue("Codigo");
                if (idAnterior.compareTo(id) != 0) {
                    idAnterior = id;
                    String name = elements.getValue("Profesor");
                    nombres.add(name);
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        } catch (ServiceException e) {
            e.printStackTrace();
        }

        return nombres;
    }

    @Override
    protected void onPostExecute(ArrayList<String> result){
        super.onPostExecute(result);
        mProgress.dismiss();
        values = result;
    }

}
