tramp: Android shell setup
4.17 Android shell setup hints
==============================
TRAMP uses the ‘adb’ method to access Android devices. Android devices
provide a restricted shell access through an USB connection. The local
host must have the Android SDK installed.
Applications such as ‘SSHDroid’ that run ‘sshd’ process on the
Android device can accept any ‘ssh’-based methods provided these
settings are adjusted:
‘sh’ must be specified for remote shell since Android devices do not
provide ‘/bin/sh’. ‘sh’ will then invoke whatever shell is installed on
the device with this setting:
(add-to-list 'tramp-connection-properties
(list (regexp-quote "192.168.0.26") "remote-shell" "sh"))
where ‘192.168.0.26’ is the Android device’s IP address. (
Predefined connection information).
TRAMP requires preserving ‘PATH’ environment variable from user
settings. Android devices prefer ‘/system/xbin’ path over
‘/system/bin’. Both of these are set as follows:
(add-to-list 'tramp-remote-path 'tramp-own-remote-path)
(add-to-list 'tramp-remote-path "/system/xbin")
When the Android device is not ‘rooted’, specify a writable directory
for temporary files:
(add-to-list 'tramp-remote-process-environment "TMPDIR=$HOME")
Open a remote connection with the command ‘C-x C-f
/ssh:192.168.0.26#2222:’, where ‘sshd’ is listening on port ‘2222’.
To add a corresponding entry to the ‘~/.ssh/config’ file
(recommended), use this:
Host android
HostName 192.168.0.26
User root
Port 2222
To use the host name ‘android’ instead of the IP address shown in the
previous example, fix the connection properties as follows:
(add-to-list 'tramp-connection-properties
(list (regexp-quote "android") "remote-shell" "sh"))
Open a remote connection with a more concise command ‘C-x C-f
/ssh:android:’.
