Cannot find the setter for attribute 'app:animate'

Hey, I have followed all the steps described in implementation of data binding for expandablecardview, but for some reason my gradle build fails with the following stack trace.

****/ data binding error ****msg:Cannot find the setter for attribute 'app:animate' with parameter type boolean on android.widget.ImageView.
  file:F:\Behtar Projects\Venus\app\src\main\res\layout\faq_item.xml
  loc:78:35 - 78:49
  ****\ data binding error ****

I have searched for a solution for hours related to my use-case, but cannot find anything working.
