If I use the room-compiler version that’s listed in the book
then everything works fine. However, if I follow the warning and upgrade to the newer version
then I receive the following build error:
criminalintentbnr4k/database/CrimeDatabase_Impl.java:7: error: cannot find symbol import androidx.room.RoomOpenHelper.ValidationResult; ^ symbol: class ValidationResult location: class RoomOpenHelper
Obviously the newer version is not final, but any insight what would have changed to make the ValidationResult class be relocated?
