databinding does not exist: How to solve it?

Question

I\'m working on an Android application with databinding but I\'ve always next error:

Error: Package my.package.databinding

Answer 1

After deleting the build folder for the project and submodules, making, rebuilding, etc etc etc, the only thing that worked for me was:

create a new layout

I think there's something in the generator that gets messed up and that flushes it (totally guessing here)
