android：MalformedURLException：找不到协议

Question

请问解决这个问题？任何帮助？

ERROR : java.net.MalformedURLException: Protocol not found: /mnt/sdcard/EREADER/NewForestPonies/OEBPS/content.opf

代码：

     //Getting the xhtml file names
                DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
                DocumentBuilder db = dbf.newDocumentBuilder();
                String 
                Document doc = db.parse(new InputSource(Environment.getExternalStorageDirectory()+"/EREADER/"+book_name+"/OEBPS/content.opf")); //ERROR HERE
                doc.getDocumentElement().normalize();

          ..........
          ......

编辑： 对于SAX PARSER：？

  DataSaxHandler myXMLHandler = new DataSaxHandler();
            xr.setContentHandler(myXMLHandler);
            xr.parse(new InputSource(Paths.getBookStorePath()+bookname+"/OEBPS/content.opf"));

Answer 1

试试这个，让我知道发生了什么......

    File fXmlFile = new File(Paths.getBookStorePath()+book_name+"/OEBPS/content.opf");
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
    Document doc = dBuilder.parse(fXmlFile);
    doc.getDocumentElement().normalize();
