Android Question Material design does not work.

I tried to use Material Design of this post:

https://www.b4x.com/android/forum/threads/new-feature-three-birds-with-one-stone.63127/#post-398974

and video:


I'm getting the error:

Error parsing manifest script:
Line=21, Word=C
Command expected.

I have attached an image with an error.

But it does not work. I use B4A 5.50.

How can I make it work?
