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--- [albinus@arthur ~]$ adb shell shell@android:/ $ 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) shell@android:/ $ 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. ^ permalink raw reply [flat|nested] 4+ messages in thread

Isn't it true that adb push/pull runs with root privledge? I haven't tested, but I don't recall ever seeing permission denied when doing adb push. ^ permalink raw reply [flat|nested] 4+ messages in thread

Always issue su and if it doesn't work, ignore the error Well, I have applied a patch to tramp-adb.el which * Performs "su <user>" if user is given in the file name * Raises an error if this command fails. With this, the usual "/adb::" still works, and "/adb:root@:" works if the device supports it. (My examples assume, that the host name is optional if there is exactly one device connected via adb) > 2. Isn't it true that adb push/pull runs with root privledge? I > haven't tested, > but I don't recall ever seeing permission denied when doing adb push. Don't know. Let's see what other people report. Maybe you must call "adb root" outside Emacs in advance; but I really don't know ... Best regards, Michael. ^ permalink raw reply [flat|nested] 4+ messages in thread
