我在为RssReader运行我的Android项目时遇到错误.

码:

URL url = new URL(urlToRssFeed);
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser parser = factory.newSAXParser();
XMLReader xmlreader = parser.getXMLReader();
RssHandler theRSSHandler = new RssHandler();
xmlreader.setContentHandler(theRSSHandler);
InputSource is = new InputSource(url.openStream());
xmlreader.parse(is);
return theRSSHandler.getFeed();

它显示以下错误:

android.os.NetworkOnMainThreadException

    // TODO Auto-generated method stub

        Uri selectedImage=data.getData();
        String[] filePathColumn={MediaStore.Images.Media.DATA};
