android - IOException BufferedInputStream 在 HTC 中关闭

Question

我在执行 BufferedReader.readLine() 时遇到了 IOException，在下面完整代码的行 while ((line = br.readLine()) != null) {) 中。 Exception.getMessage() 返回 BufferedInputStream is closed。

它只发生在 HTC 设备上，当我使用 Sony Ericsson XPERIA 时它不会发生。

我的完整代码:

public static String downloadString(String url) throws MalformedURLException, IOException {     
    InputStream is = downloadStream(url);

    //Convert stream into String
    String line;
    BufferedReader br = new BufferedReader(new InputStreamReader(is), 4096);            
    StringBuilder sb =  new StringBuilder();
    while ((line = br.readLine()) != null) {
        sb.append(line);
    }
    br.close();
    return sb.toString();
}

public static InputStream downloadStream(String url) throws MalformedURLException, IOException {
    return connection(url).getInputStream();
}

private static HttpURLConnection connection(String s_url) throws MalformedURLException, IOException {
    URL url = new URL(s_url);
    HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
    urlConnection.setRequestMethod("GET");
    urlConnection.setDoOutput(true);
    urlConnection.connect();

    return urlConnection;
}

如何制作适用于所有设备的更好的 downloadString 方法？

提前致谢。非常感谢您的回答

试一试 -

public static String getContent(String url) throws Exception {
      return(new Scanner(new URL(url).openConnection().getInputStream()).useDelimiter("/z").next());
}
