RoomDatabase.PrepackagedDatabaseCallback

Kotlin |Java

public static abstract class RoomDatabase.PrepackagedDatabaseCallback
extends Object

java.lang.Object
↳	androidx.room.RoomDatabase.PrepackagedDatabaseCallback

Callback for RoomDatabase.Builder.createFromAsset(String), RoomDatabase.Builder.createFromFile(File) and RoomDatabase.Builder.createFromInputStream(Callable)

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.
