View must have a tag error in android data binding

Question

I\'ve two layouts for a screen. Activity works fine while setting a layout for Mobile device but it\'s causing error while setting layout for tablet device. The main issue is:

Answer 1

I ran into this when I had:

• A library module defining a layout resource
• An app module that depended upon that library module defining the same layout resource
• The library layout resource was set up for data binding (e.g., root element), but the app module's edition of that layout resource was not

In my case, the app module's layout was left over from when I created the project. Removing it cleared up the problem.
