RoomDatabase.PrepackagedDatabaseCallback

public abstract class RoomDatabase.PrepackagedDatabaseCallback

Callback for Builder.createFromAsset, Builder.createFromFile and Builder.createFromInputStream

This callback will be invoked after the pre-package DB is copied but before Room had a chance to open it and therefore before the RoomDatabase.Callback methods are invoked. This callback can be useful for updating the pre-package DB schema to satisfy Room's schema validation.
