How would you run AsyncTask tasks?

The below class can be run with new DownloadFilesTask().execute(url1, url2, url3);

private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> {

protected Long doInBackground(URL... urls) {

int count = urls.length;

long totalSize = 0;

for (int i = 0; i < count; i++) {

totalSize += Downloader.downloadFile(urls[i]);

publishProgress((int) ((i / (float) count) * 100));

if (isCancelled()) break;

}

return totalSize;

}

protected void onProgressUpdate(Integer... progress) {

setProgressPercent(progress[0]);

}

protected void onPostExecute(Long result) {

showDialog("Downloaded " + result + " bytes");

}

}
