Android smb: jcifs.smb.SmbException:协商失败

Question

我正在尝试使用smb开发一个android应用程序。我正在尝试列出LAN中可用的网络位置。我使用以下代码来完成此操作：

            SmbFile[] domains;
            domains = (new SmbFile("smb://")).listFiles();
            for (int i = 0; i < domains.length; i++) {
                SmbFile[] servers;
                try {
                    servers = domains[i].listFiles();
                } catch (SmbException e) {
                    // TODO Auto-generated catch block
                       e.printStackTrace();
                }
                for (int j = 0; j < servers.length; j++) {
                    System.out.println("Network places....  " +servers[j].getName());
                }
            }

        } catch (SmbException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (MalformedURLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

我正在获取网络列表，但随机得到以下异常：

我不能想出如何解决这个异常(谷歌了很多没有运气)。请建议如何解决此异常。提前谢谢。

确保您使用的是最新的jar，即jcifs-1.3.15.jar，而不是jcifs-1.1.11.jar等较低版本
