First check this out: are following packages installed?
I had to install necessary packages need for file managers:
# pacman -S gvfs-mtp gvfs-gphoto2
Now start up your file manager with gvfs support for instance Thunar up to check if your Android device is mounted.
Checked if my Asus memo tablet was noticed:
Device 0 (VID=0b05 and PID=7773) is a Asus Fonepad 7 (FE375CXG).
and a lot of other lines. You also can use lsusb to check.
$packer -S jmtpfs
Created a mtp folder in /home/paul/
In Openbox I created a new keybinding keybind key="W-m" in .config/openbox/rc.xml with this as command:
xterm -e "jmtpfs ~/mtp"
So after creating that and restarting openbox with
I start up Thunar. I now see in /homepaul/mtp/ two folders Internal Storage and SD Card and the files can be copied etc.
