ClassNotFoundException android.view.WindowManager.LayoutParams

I try to prevent applications from creating windows over all other applications, original XPrivacy could handle this: https://github.com/M66B/XPrivacy/blob/b88626cde79f3b2d249298292902ba02678ec1af/src/biz/bokhorst/xprivacy/XWindowManager.java#L56
As an example target I took DevInfoOverlay: https://play.google.com/store/apps/details?id=ru.andr7e.devinfooverlay
A try to hijack WindowManager.addView - here is my definition:
addView.json
As a result - class of the second argument not found:

PrivacyEx.addView

I also tried android.view.ViewGroup.LayoutParams instead of android.view.WindowManager.LayoutParams - result is the same.

I found that it was a common Xposed issue when it was needed to load class from classes2.dex of multi-dex apk. But it's not that case: given target has only one classes.dex.
