I have update the support library to 23.2.0 Since the update I get this error at build time :
\\app\\build\\intermediates\\data-binding-layout-out\\de
Faced same bug. In my case problem was in 3rd-party library, that I didn't update to the version, that use same app-compat vesrion as depency as in my project.
So try to update another libs, that use app-compat lib as depency.
