I have git pulled latest Emacs and built it.

Repository revision: b87400c78b047d242ae188c46c621e0e8a8e69b2
Repository branch: master

tramp-connection-properties ⇒ (("ssh:motorola" "tmpdir" /storage/emulated/0/tmp) ("scp:motorola" "tmpdir" /storage/emulated/0/tmp))

I have only added today the scp version, but it always worked in past.

OK now I evaluate this one, though I do not understand it:

(connection-local-set-profile-variables
 'tramp-connection-local-termux-profile
 `((tramp-remote-path
    . ,(mapcar
	(lambda (x)
	  (if (stringp x) (concat "/data/data/com.termux/files" x) x))
	(copy-tree tramp-remote-path)))))

> (connection-local-set-profiles

>  'tramp-connection-local-termux-profile)

(connection-local-set-profiles
 '(:application tramp :machine "scp:motorola")
 'tramp-connection-local-termux-profile)

I have tried above, I have tried with :machine "motorolausb" and I
get:

File error: Couldn't find a proper `ls' command
tramp-error: Couldn't find a proper `ls' command
