JCIFS SmbFile.listFiles崩溃

Question

首先，我想说我确实有Internet权限。

我尝试这样做

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

当file.listFiles（）尝试运行时，新的SmbFile（...）可以正常运行，并出现以下错误...

03-25 02:47:17.749: E/AndroidRuntime(4552):     at jcifs.smb.SmbFile.listFiles(SmbFile.java:1648)

那么它没有连接吗？我不确定为什么会这样，我已经浪费了互联网。以前找不到与此人有此问题的人...

Answer 1

“由以下原因引起：android.os.NetworkOnMainThreadException”

您正在尝试在主线程上访问网络。有几种避免此错误的方法，最推荐的方法是使用AsyncTask。

这是有关AsyncTask的文档。
