Tramp access to Android?

[Skip Montanaro]

Prompted by the discussion about calendar access between Emacs
(presumably running on a "big" computer of some sort) and Android, I
recently tried unsuccessfully to access files on my Android phone from
my Linux laptop. I had installed SimpleSSH on the phone, and can ssh
into it from the shell prompt. Tramp prompts for a password (which is
accepted, I believe), but hangs after finding a remote shell prompt.
Here's the output from my *Messages* buffer:

Tramp: Opening connection for 192.168.97.156#2222 using ssh...
Tramp: Sending command ‘exec ssh  -p 2222 -o ControlMaster=auto -o
ControlPath='tramp.%C' -o ControlPersist=no -e none 192.168.97.156’
Tramp: Waiting for prompts from remote shell...
Tramp: Sending password [2 times]
Tramp: Waiting for prompts from remote shell...done
Tramp: Found remote shell prompt on ‘192.168.97.156’
Tramp: Opening connection for 192.168.97.156#2222 using ssh...failed
Quit [2 times]

tramp-verbose was set to 10. Should I try 11? :-)

Thx,

Skip
