You can also update UI thread from background thread in this way also:

Handler handler = new Handler(); // write in onCreate function

//below piece of code is written in function of class that extends from AsyncTask

handler.post(new Runnable() {
    @Override
    public void run() {
        textView.setText(stringBuilder);
    }
});
