Apache VFS的SSH URI错误

Question

I'm getting the following error in an Android application with Apache VFS and I can't find much on the google to help. I'm trying to upload a file via SSH and I get this rather vague error. The URI, as reported in logcat, looks correct to me according to the VFS docs. The only thing I can figure is that it only expects to see a local network host instead of a TLD. Is this true, and if so, how do I fix it? If not, what looks wrong about this URI to you?

Caused by: org.apache.commons.vfs2.FileSystemException: Expecting / to follow the hostname in URI "sftp://username:***@mydomain.com/public_html/". 

The errors are the same with or without a specific destination filename.

Here's the full logcat output.

Answer 1

I suspect you have a problematic character in the password (as this is the only info not shown). You need to percent-encode the username and password before adding it to the URL.
