        textView.setVisibility(VISIBLE);
    }

    public void onModifiedTextView(final String title) {
        runOnUiThread(new Runnable() {
            public void run() {
                textView.setText(title);
                textView.invalidate(); // not even necessary
            }
        });
    }

    public class DownloadWebPageTask extends AsyncTask<String, Void, String> {
        public DownloadWebPageTask(MainActivity mainActivity) {
            this.callback = mainActivity;
        }

        private MainActivity callback;
        private …
