Question

我的Google云端硬盘上托管了一个XML文件。它有一些我的Android应用程序运行所需的数据。所以，我决定测试是否可以从文件中获取数据并进行测试SAXParser。但是，我得到SAXParseException：

org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1; Premature end of file.
    at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(Unknown Source)

虽然这个相同的代码适用于RSS提要，但它会崩溃为Google驱动器文件以下是我打开流的方式：

try{
            SAXParserFactory factory = SAXParserFactory.newInstance();
            SAXParser parser = factory.newSAXParser();

            InputStream stream = new URL(url).openStream();
            Reader r = new InputStreamReader(stream,"UTF-8");
            InputSource source = new InputSource(stream);
            source.setEncoding("UTF-8");

            parser.parse(source, this);
        }catch(Exception e){
            errorOccured = true;
            e.printStackTrace();
        }

我该如何解决？

您的InputStream存在一些问题，请仔细阅读：http://www.danielschneller.com/2008/01/saxparseexception-1-1-premature-end-of.html

SAXParseException：文件过早结束
