Updating progress dialog

Question

I am trying to make an application that can help me to evaluate the time to download the file from a web resource. I have found 2 samples:

Download a file with Android,

Answer 1

The second example may run faster, but it monopolizes the GUI thread. The first approach, using AsyncTask, is better; it allows the GUI to stay responsive as the download proceeds.

I found it helpful to compare AsyncTask with SwingWorker, as shown in this example.

Answer 2

first link is best. But i can't provide code( it's home comp) in monday or later i can provide full function. But :

private class DownloadFile extends AsyncTask<String, Integer, String>{
    @Override
    protected String doInBackground(String... url) {
        int count;
        try {
            URL url = new URL(url[0]);
            URLConnection conexion = url.openConnection();
            conexion.connect();
            // this will be useful so that you can show a tipical 0-100% progress bar
            int lenghtOfFile = conexion.getContentLength();

            // downlod the file
            InputStream input = new BufferedInputStream(url.openStream());
            OutputStream output = new FileOutputStream("/sdcard/somewhere/nameofthefile.ext");

            byte data[] = new byte[1024];

            long total = 0;

            while ((count = input.read(data)) != -1) {
                total += count;
                // publishing the progress....
                publishProgress((int)(total*100/lenghtOfFile));
                output.write(data, 0, count);
            }

            output.flush();
            output.close();
            input.close();
        } catch (Exception e) {}
        return null;
    }

this class are best for it ( imho) . publishProgress it's simple function where u have max two lines. Set max and set current. How u can see in this code lenghtOfFile it's how many bytes have ur file. total-current progress ( example 25 from 100 bytes) . Run this class easy : DownloadFile a = new DownloadFile(); a.execute(value,value);//or null if u not using value. Hope u understand me , im not good speaking on english.
