Re: Enable adb port in tramp adb

Hi, Michael,

Because adb also supports host names, I find tramp can't easily guess port name for user now. For example, the host name of one device is same as another device's serial number:
$ adb devices
List of devices attached
014994ab    device
014994ab:5554    device

and if user type "/adb:014994ab:", tramp can't decide which one user want to access. So I think we'd better not guess port name for user.

Best regards

Hi Zhongwei,

I've played a little bit with your patch.

How do you detect, that adb runs in usb mode? I couldn't find a
respective adb command.

The only indication might be, that connections listed via "adb devices"
show a port number, or not. Devices without a port number might be
connected in usb mode.

That's OK. The listed port number shall be used than.

Could it be, that one could access a device twice, on different ports?

Furtheron, I found some other use cases which are not handled yet, I
believe. If a device is not listed in "adb devices", Tramp shall first
connect to that device with "adb connect device:port". Afterwards, Tramp
could access to this device via "adb -s device:port shell", as it does
already for usb devices.

And it looks, like adb does support also host names, not only ip
addresses. Look at my example (my Nexus 7 uses

# nslookup
Address:      name =

# adb connect android-c05807abea645fdf:5555
connected to android-c05807abea645fdf:5555

# adb devices
List of devices attached
015d24bc55282409        device
android-c05807abea645fdf:5555   device

No problem here, it passes.
