If you want to update the view from async after complete process in then you can use

protected void onPostExecute(String result)
    {
        textView.setText(result);
    }

But if you want to update data while running background process then use. For ex...

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));<------
         }
         return totalSize;
     }

     protected void onProgressUpdate(Integer... progress) {  <-------
         setProgressPercent(progress[0]);
     }
