Sax error on hero
<p>I'm using sax parser to get xml data, the below code is causing my app to crash. </p>

<pre><code>    try {
        url = new URL("The URL");
    } catch (MalformedURLException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }
   // RssFeed feed = null;
    try {
        feed = RssReader.read(url);
    } catch (SAXException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
</code></pre>

<p>Looks like it is crashing at <code>feed = RssReader.read(url);</code> It works fine on my evo but when I install it on my hero the below error occurs</p>
