I was trying to get current version name of my android studio project. after updating my Studio to 3.6.1 i am facing difficulty in importing BuildConfig
I've noticed this as well.
It was after a 'Clean Project' that AS forgot the import com.my_project.BuildConfig; statement.
Restoring the import statement manually wherever it was complaining about BuildConfig and then doing a 'Rebuild Project' seemed to work, at least until the next time.
Tip: don't accept the offered suggestion to import the class from ...compat.v4... you want the app level definition.
Update April 4th: The newly released AS 3.6.2 doesn't seem to suffer from this problem.
