here I face one problem after updating this both API level 20 (L and W). in my XML Graphical view the layout is not generated instead it is showing me this error:
Missing styles. Is the correct theme chosen for this layout? Use the Theme combo box above the layout to choose a different layout, or fix the theme style references.
and also shows an error in res/values/styles.xml in this line
style name="AppBaseTheme" parent="Theme.AppCompat.Light
I use Eclipse juno.
