My CollapsingToolbarLayout crashes because of Error inflating class android.support.design.widget.CollapsingToolbarLayout. I updated the android studio last weekend. Before the updated, it works fine. After I updated it, it crashed. However, I tried to downgrade it to 2.0.0 version and it's not working anymore.
