Room database migration if only new table is added

Question

Let\'t assume, I have a simple Room database:

@Database(entities = {User.class}, version = 1)
abstract class AppDatabase extends RoomDatabase {
    public ab         


        

Answer 1

In this case, you don't need to do a migration, you can call .fallbackToDestructiveMigration() when you are creating database instance.

Example:

    instance = Room.databaseBuilder(context, AppDatabase.class, "database name").fallbackToDestructiveMigration().build();

And don't forget to change database version.
