Since the last update of android studio (2.3 Beta 1). I have an error for viewing layouts. The designs are just gray screens and nothing is showing. I have already tried several solutions proposed but none have worked. I already tried :
- Rebuild and re-sync project with gradle option
- Invalidate caches
- Change Android rendering version
- Checking updates and install latest version
Rendering failed with a known bug. Please try a rebuild.
The following classes could not be instantiated:
- android.support.v7.widget.AppCompatButton (Open Class, Show Exception, Clear Cache)
- android.support.v7.widget.AppCompatEditText (Open Class, Show Exception, Clear Cache)
- android.support.v7.widget.AppCompatTextView (Open Class, Show Exception, Clear Cache)
Tip: Use View.isInEditMode() in your custom views to skip code or show
sample data when shown in the IDE. If this is an unexpected error you can
also try to build the project, then manually refresh the layout.

Do you have any idea where this may come from?
