Making the ubuntu 12.10 recognize your Android (internal and external sdcard) and adding usb rules security (udev)

If you plug your android phone or tablet on your Ubuntu 12.10 and nothing is happening, follow this next steps and magically your cell phone will be recognized:

sudo add-apt-repository ppa:langdalepl/gvfs-mtp
sudo apt-get update
sudo apt-get install libmtp-common libmtp-dev libmtp-runtime libmtp9 mtp-tools gmtp python-pymtp libusb-dev gvfs

The follow code is to register your device on usb dev rules of linux:

wget http://downloads.sourceforge.net/project/libmtp/libmtp/1.1.1/libmtp-1.1.1.tar.gz
tar -xvf libmtp-1.1.1.tar.gz
cd libmtp-1.1.1
./configure --prefix=/usr
make
sudo make install
sudo cp 69-libmtp.rules /etc/udev/rules.d
sudo service udev restart
