JCIFS SmbFile.listFiles崩溃

Question

首先，我想说的是，我确实拥有互联网权限。

我试着这样做

jcifs.Config.registerSmbURLHandler();
SmbFile file = new SmbFile("smb://");
SmbFile[] files = file.listFiles();

新建SmbFile(...)执行正常，当file.listFiles()尝试运行它时崩溃，并出现以下错误...

那么它是不是连接不上了？我不确定为什么会发生这种情况，我已经在互联网上怒目而视了。我找不到以前遇到过这个问题的人...

按照注释的要求，下面是崩溃后的完整错误列表

Answer 1

“原因: android.os.NetworkOnMainThreadException”

您正试图在您的主线程上访问网络。有几种方法可以避免这个错误，最推荐的方法是使用AsyncTask。

以下是有关AsyncTask的文档。

Answer 2

NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication("",
            username, password);

sFile = new SmbFile(path, auth);

files = sFile.listFiles();

路径应指定为smb://ipadress/pathtosharefolder/

用户名、密码--用于访问网络的用户名和密码
