Appreciate the help.

The exception says: [..]ConstraintLayout cannot be cast to [..]CircleImageView so it seems findViewById(R.id.setup_image) returns a ConstraintLayout - that's not an issue with this library. Please double-check your IDs and maybe clean the project.

what do you mean by check your IDs and maybe clean the project?

[hdodenhof]

Make sure that (a) @+id/setup_image is only used once, at the correct place and (b) you are inflating the correct layout. Use "Clean Project" from the "Build" menu in Android Studio.
