Automounting MTP devices

Question

Hi all,
I tried a lot of techniques to mount MTP devices (such as the latest Android devices without a SD card) automatically when plugged-in. gvfs-gphoto2 kinda worked, but for me it was dreadfully slow, and the only reliable solution, at this time, was to use go-mtpfs. But then it's not automatic, you have to type horribly complicated commands in a terminal! Yuck.
In the PKGBUILD below, a few UDEV rules to fix that. They currently only work with the devices I got (Nexus 7 and Galaxy Nexus, both on CyanogenMod 10), so they definitely won't work on anything else, which is why I didn't submit them right now to the AUR. I just wanted to share them in case anybody was interested. And since it's my first PKGBUILD (hurray!), do share any tips you might have regarding, oh, I don't know, something I might have forgotten, a rule I didn't know about, or something that could be done better.
Cheers!

Thanks for you Package, I was trying to use go-mtpfs and a single rules file (adapted from http://bernaerts.dyndns.org/linux/247-u … exus7-mtp) in /etc/udev/rules.d without success.
I've made a few modifications based on http://hackaday.com/2009/09/18/how-to-write-udev-rules/ in your /usr/bin/mtp file to have mount and unmount notifications under Gnome Shell.
There's a problem, unmount notifications doesn't work, if you have an idea...
here is the modified file:
#!/bin/bash

GO_MTPFS=/usr/bin/go-mtpfs
DEVICE_NAME=${2//_/ }
GSuser=$(ps -ef | grep -w /usr/bin/gnome-shell | grep -v grep | awk '{print $1'})
GSpid=$(ps -ef | grep -w /usr/bin/gnome-shell | grep -v grep | awk '{print $2'})
DBUS_SESSION_BUS_ADDRESS=`grep -z DBUS_SESSION_BUS_ADDRESS /proc/$GSpid/environ | sed -e 's/DBUS_SESSION_BUS_ADDRESS=//'`
case $1 in
start|mount)
echo "Mounting MTP device on /media/$DEVICE_NAME"
/bin/mkdir -p "/media/$DEVICE_NAME"
/usr/sbin/daemonize -l /var/lock/go-mtpfs.$2.lock /usr/bin/go-mtpfs -allow-other=true "/media/$DEVICE_NAME"
if [ -r "/home/$GSuser/Images/$DEVICE_NAME.png" ]
then
sudo -b -u $GSuser DBUS_SESSION_BUS_ADDRESS=$DBUS_SESSION_BUS_ADDRESS notify-send --hint=int:transient:1 -t 6000 "$DEVICE_NAME monté sous /media/$DEVICE_NAME" -i "/home/$GSuser/Images/$DEVICE_NAME.png"
else
sudo -b -u $GSuser DBUS_SESSION_BUS_ADDRESS=$DBUS_SESSION_BUS_ADDRESS notify-send --hint=int:transient:1 -t 6000 "$DEVICE_NAME monté sous /media/$DEVICE_NAME"
fi
stop|unmount)
echo "Unmounting MTP device on /media/$DEVICE_NAME"
/bin/umount "/media/$DEVICE_NAME"
/bin/rmdir "/media/$DEVICE_NAME"
if [ -r "/home/$GSuser/Images/$DEVICE_NAME.png" ]
then
sudo -b -u $GSuser DBUS_SESSION_BUS_ADDRESS=$DBUS_SESSION_BUS_ADDRESS notify-send --hint=int:transient:1 -t 6000 "$DEVICE_NAME démonté" -i "/home/$GSuser/Images/$DEVICE_NAME.png"
else
sudo -b -u $GSuser DBUS_SESSION_BUS_ADDRESS=$DBUS_SESSION_BUS_ADDRESS notify-send --hint=int:transient:1 -t 6000 "$DEVICE_NAME démonté"
fi
echo "Usage: android-mtp start device-name"
esac
Another problem, if the device is locked (I'm using the schema lock) it will not mount (it try to mount, fail, then unmount), Is there a way to send a notification to the user telling him to disconnect, unlock and retry? I'm anable to find a way to do this.
