That's not so simple I fear. We could add the "su" command to the
initial hand-shaking. But there is the problem, that Tramp copies files
from/to Android devices by "adb pull" and "adb push", which have the
same permissions as adbd on the device. Even if you could navigate in
the directories being root, you wouldn't be able to open files.

Furthermore, the "su" command does not exist on unrooted devices. I own
an unrooted "Nexus S" for testing, and it tells me

--8<---------------cut here---------------start------------->8---
address@hidden ~]$ adb shell
address@hidden:/ $ id
uid=2000(shell) gid=2000(shell) 
groups=1003(graphics),1004(input),1007(log),1009(mount),1011(adb),1015(sdcard_rw),1028(sdcard_r),3001(net_bt_admin),3002(net_bt),3003(inet),3006(net_bw_stats)
address@hidden:/ $ su
/system/bin/sh: su: not found
--8<---------------cut here---------------end--------------->8---

Alternatively, if you have a running sshd on the device, you could use
the usual ssh-based methods for access. See the Tramp manual for setup
hints.

Best regards, Michael.
