floating action menus and buttons not getting the styles

[3nomis]

I don't know why my floating action button inside a CoordinatorLayout is not getting any custom styles, even if I write them straight in the xml file it doesn't appear with the color and the attributes I set.
Is it only me having this issue?

I had your same problem.

Fixed changing the namespace from:
xmlns:fab="http://schemas.android.com/tools"

To:
xmlns:fab="http://schemas.android.com/apk/res-auto"

Also, make sure to implement correct behavior.
