Hello All -
I am trying to upload a file from the Android (Emulator or I/O phone)
and get a cannot connect to server error. I saw a variety of posts,
but never a solution. The same accounts, URLs and passwords work from
the shell.
The following code is "Hello Android" extended to call my FTP code.
(accounts, passwords changed).
Does FTP upload work?
Is there a sample to work from?
Any other ideas?
(P.S. I would gladly use HTTP instead but found that more confusing
and got a different error. So a sample there would be great as well).
- Andy
