It just happened right after upgrading to v2.2, where androids studio is showing the full package name of the project for each package I create!
Anyone has any idea how to hide the full package name and just showing the package name the I am creating?
This is because you have the
Flatten Packages option active. To return to the default behavior you must turn this option off by going to your Project view at the left side (usually) and then on the click
Show Option Menu Icon (a little cog on the top of this sidebar)

EDIT: Sorry it seems I cannot yet post a comment to a reply ?
There is currently a bug issued here about the same problem fairly recent
They suggest that the bug has to do with enabling
dataBindings in your project and they already looking for a fix to this as we speak.
On the other hand if you do not have
dataBindings enabled please try the following: Close AStudio, remove the .idea folder from your project, and then import your project again.
