android：java.io.IOException：流关闭

Question

我正在从服务器读取xml数据并解析它，在此期间我收到以下异常。

05-07 12:37:31.904: W/System.err(2765): java.io.IOException: stream closed

我的代码是

**private static InputStream downloadUrl(String urlString) throws IOException { 
     System.setProperty("http.keepAlive", "false"); 

**///// added after some search about this exception, but it didnt fix the issue fo**r me 

     URL url = new URL(urlString); 
     HttpURLConnection conn = (HttpURLConnection) url.openConnection(); 
     //conn.setReadTimeout(10000 /* milliseconds */); 
     conn.setConnectTimeout(15000 /* milliseconds */); 
     conn.setRequestMethod("GET"); 
     conn.setDoInput(true); 
     // Starts the query 
     conn.connect(); 
     return conn.getInputStream(); 
    }** 


XmlPullParser parser = getParser(in); 
parser.require(XmlPullParser.START_TAG, ns, "response"); 

      while (parser.next() != XmlPullParser.END_TAG) { 
........ 
} 

解析成功在XML文件中第几个记录，然后该异常来

问题同XmlPullParser。它在下载大文件时有一些已知问题。我将我的XML解析更改为使用DOM。 http://developer.android.com/reference/javax/xml/parsers/package-summary.html 它的工作
