我想解析我的桌面上的xml文件。我得到一個錯誤

Question

解析代碼：

private UrlList parseUrl(URL url) { 
    URL SourceUrl = null; 
    SourceUrl = url; 

    try { 
     /** Handling XML */ 
     SAXParserFactory spf = SAXParserFactory.newInstance(); 
     SAXParser sp = spf.newSAXParser(); 
     XMLReader xr = sp.getXMLReader(); 
     /** Create handler to handle XML Tags (extends DefaultHandler) */ 
     XMLParser myXmlParser = new XMLParser(); 
     xr.setContentHandler(myXmlParser); 
     xr.parse(new InputSource(SourceUrl.openStream())); 

    } catch (IOException e) { 
     e.printStackTrace(); 
    } catch (Exception e) { 
     System.out.println(" XMLParsing error is : " + e); 
    } 

    urlList = XMLParser.urlList; 
    return urlList; 
}// end of parseurl 

URL中的IAM給予是
sourceUrl =新的URL（「文件：// C：/Users/raghu/Desktop/aero/products.xml 「）; 同樣，我有足夠的資源路徑也以同樣的方式

file://C:/Users/raghu/Desktop/aero/"resource sub folders" 

我收到以下錯誤

您需要將文件推入Android模擬器文件系統。例如。

adb push C:/Users/raghu/Desktop/aero/products.xml /sdcard/products.xml 

並使用後一種路徑。
