Question

我正在开发一款使用sftp在手机和服务器之间传输文件的Android应用。目前我正在使用jsch（0.1.45）和spongycastle。一切正常，除了Honeycomb（在ICS上工作正常），我已经尝试了我能想到的一切。

连接和列出文件的行为符合预期，但当我尝试更改远程目录或传输文件时，我得到以下异常：

01-01 20:42:40.270: E/SFTP(362): Caused by: java.io.IOException: inputstream is closed
01-01 20:42:40.270: E/SFTP(362):    at com.jcraft.jsch.ChannelSftp.fill(ChannelSftp.java:2529)

01-01 20:42:40.270: E/SFTP(362):    at com.jcraft.jsch.ChannelSftp.cd(ChannelSftp.java:300)

如果我在调试模式下启动ssh服务器，我得到：

debug2: fd 3 setting TCP_NODELAY
debug3: packet_set_tos: set IP_TOS 0x08
debug2: fd 11 setting O_NONBLOCK
debug2: fd 10 setting O_NONBLOCK
debug2: fd 13 setting O_NONBLOCK
debug2: channel 0: read 641 from efd 13
debug3: channel 0: discard efd
Bad packet length 920403810.
Disconnecting: Packet corrupt

Jsch logger给了我以下内容：

是否有人使用jsch蜂窝工作正常工作？

Answer 1

经过几天撞到这个，我终于发现了问题。当我将我的应用程序调整为蜂窝时，我使用AsyncTasks从UI线程中删除了所有网络调用。显然我忘了删除其中一个电话，而且Exception正在被忽视而滑落。奇怪的是，它正在与ICS合作。

显然，JSch和Honeycomb没有任何问题。只是一个沉睡的开发人员。现在一切正常。
