MTP Support for in Ubuntu12.10 or 12.04 to connect Android 4.0

Gvfs has been updated in Ubuntu 13.04 Raring Ringtail, bringing a new MTP backend which allows users to access Android 4.0 devices which do not support the USB Mass Storage protocol.

or some reason, there are no thumbnails for images on the Android device in Nautilus and the images can't be opened directly from the device but copying and viewing them on the computer works. These issues aren't Ubuntu 12.10 or 12.04 specific and they even occur in Ubuntu 13.04.

The packages in this PPA may be unstable. Use the PPA at your own risk! There are instructions on how to revert the changes at the bottom of the post.

1. To add the Gvfs (and libmtp) PPA created by the Gvfs MTP backend developer in Ubuntu 12.04 or 12.10, use the following commands:

sudo add-apt-repository ppa:langdalepl/gvfs-mtp
sudo apt-get update

(Very important to run a system update before restart) 

 Once everything has been updated successfully, restart your computer, unlock your Android device, connect it via USB and it should show up in your file manager.

Revert the changes (purge the PPA)

To revert the changes (downgrade all the packages from our Gvfs PPA to the version available in the official Ubuntu repositories), firstly install PPA-Purge with multi-arch support from the main WebUpd8 PPA.

Then, purge the PPA using the following command:

sudo ppa-purge ppa:langdalepl/gvfs-mtp 

Wait for the packages to be downgraded successfully, restart the computer and everything should go back to the way it was before adding the Gvfs PPA above.
