I have the following error in my preview window in the latest version of Android Studio (1.2) that stops me from being able to view the layout I am creating, I have tried restarting android studio several times as well as cleaning, rebuilding the project and restarting my computer
EDIT:
Some projects have the same error while other older projects work fine
The following classes could not be instantiated:
