I am following along and I have gotten up to adding the data binding items. The project has built alright until I added the data binding stuff. I have compared the Chapter 2 solution code to mine and I can’t find any issues but Mine will not build. I get the following error:

Android resource linking failed
com.example.pennydrop.app-mergeDebugResources-46:/layout/player_list_item.xml:52: error: ‘@{switchHidden ? View.INVISIBLE : View.VISIBLE’ is incompatible with attribute visibility (attr) enum [gone=2, invisible=1, visible=0].
error: failed linking file resources.

Can you give me some pointer as to where I might look to fix this error?

PS. When I do the suggested updates (gradle) to the chapter 2 solution code that Android Studio tells me I should do, it fails and won’t build as well. Just a FYI. I’m using Chipmunk.
