Tramp access to Android?

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

But then I would like to see the complete Tramp debug buffer.

You could set tramp-verbose to any value larger than 10. But Tramp won't
change its behavior, 10 is the largest value it cares about.

Btw, have you tried the "adb" method instead of "ssh", accessing your
Android device?

Best regards, Michael.

Thanks for the quick response Michael. I'm not sure I've ever
encountered a package maintainer (in the Emacs ecosystem or anywhere
else) who is as responsive as you.

Ah, missed that. See attached file. BTW, 11 was a joke which maybe
doesn't translate well out of the US:

I was unaware of that. I got an error about not being able to find an
adb command, so found an adb package, installed it, and verified that
I now have /usr/bin/adb. All that did was change the error message,
and I'm not sure where to go with this next. A quick skim of the adb
man page suggests only USB-connected devices are supported.

Thanks, I didn't know this.

Thinking about, I should perhaps add a new debug level 42, the next
after 10. With this level, Tramp explains to you what went wrong, and
how you could fix it. New features are added on-the-fly.

This would ease my life :-)

In theory, adb could go also over the air. I haven't tried it, and
indeed, the default configuration requires USB connection for adb.

Looking at the traces:

The exec call succeeded. You have reached your Android shell, which
shows you the prompt ":/storage/emulated/0 $"

> 18:34:54.121314 tramp-send-command (6) # exec env ENV='' HISTFILE=~/.tramp_history PROMPT_COMMAND='' PS1=\#\$\  PS2='' PS3='' /bin/sh

Now, Tramp tries to open a local shell, calling /bin/sh. This fails. The
output is

> 18:34:54.203451 tramp-accept-process-output (10) # *tramp/ssh 192.168.86.249* run *tramp/ssh 192.168.86.249*

> :/storage/emulated/0 $

This is likely, because Tramp has sent "PS1=\#\$\ ", and it expects a
respective prompt. But the prompt is still ":/storage/emulated/0 $".

There's nothing Tramp could do else. The sshd daemon does not work as
expected on the Android device. Which daemon do you run there? People
have reported they could get it work with Termux or SSHDroid. But I have
no experience with them, 'tho.
