Android Question style/Widget.Design.TextInputLayout not found.

[rad]

Hi pals...

I'm almost frustrated looking for the cause of this problem.
After I upgraded to B4A V.12, I always failed to compile and build my application.

always message:

Linking resources Error
error: resource style/Widget.Design.TextInputLayout (aka id.washola.v701:style/Widget.Design.TextInputLayout) not found.
error: failed linking references.

Can anyone help me to solve the issues. please...

1. Check the top message in SlidingMenu tutorial: https://www.b4x.com/android/forum/threads/jfeinstein10-slidingmenu-library.36482/
2. Which libraries are you using? There are some old libraries that are not compatible with AndroidX sdk.
