所以这发生了：

我正在从Web上解析XML，以显示在android活动上显示的天气，它适用于较小的尺寸（最多3个对象），但是当我对4,5执行相同操作时，它只会抛出该异常（全部在实际解析之前）：

   URL requestURL = new URL(queryString);

    urlConnection = (HttpURLConnection) requestURL.openConnection();
    urlConnection.setRequestMethod("GET");
    urlConnection.connect();

    InputStream inputStream = urlConnection.getInputStream();

    StringBuilder builder = new StringBuilder();

    reader = new BufferedReader(new InputStreamReader(inputStream));

    String line;
    while ((line = reader.readLine()) != null)
        builder.append(line);

   if (builder.length() == 0)
       return null;

    weatherResultString = builder.toString();

    if(format_podatkov.equals("xml")) {
        DocumentBuilderFactory builderFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder docBuilder = builderFactory.newDocumentBuilder();
        Document dokumentXML = docBuilder.parse(new InputSource(new StringReader(weatherResultString)));

在while循环条件中引发异常...有什么想法吗？
