我正在開發一個使用sftp在手機和服務器之間傳輸文件的Android應用程序。目前我使用jsch(0.1.45)和海綿堡。一切工作正常,除了Honeycomb(在ICS上正常工作),我已經嘗試了所有我能想到的。JSch on Honeycomb

連接和上市文件表現爲預期的,但是當我試圖改變遠程目錄或傳送文件,我得到以下異常:

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) 

如果我開始在調試模式下的SSH服務器,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記錄儀給我下面的:

有沒有人用jsch在蜂窩上正確工作?

經過一段時間,我的頭撞到這一個我終於發現了問題。當我將我的應用程序改編爲蜂巢式時,我使用AsyncTasks從UI線程中刪除了所有網絡調用。顯然我忘了刪除其中的一個電話,而且Exception被人忽視了。奇怪的是,它正在與ICS合作。

顯然,JSch和Honeycomb沒有任何問題。只是一個睏乏的開發人員。現在一切正常。
