ProgressDialog does not appear
<pre><code>WebView webView = new WebView(this);        
    webView.getSettings().setJavaScriptEnabled(true);
    webView.getSettings().setUserAgentString("Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.7 (KHTML, like Gecko) Chrome/7.0.517.44 Safari/534.7");
    webView.setWebViewClient(new HelloWebViewClient());
    ProgressDialog dialog = ProgressDialog.show(this, "", 
                    "Loading. Please wait...", true);
    setContentView(webView);
    webView.loadUrl("http://www.preisjaeger.at");
    dialog.cancel();
</code></pre>

<p>Why does the <code>ProgressDialog</code> not appear?</p>
