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

You can do this way-

@Database(entities = {User.class, Pet.class}, version = 2)

abstract class AppDatabase extends RoomDatabase {
public abstract Dao getDao();
public abstract Dao getPetDao();
}

Remaining will be same as you have mentioned above-

 db = Room.databaseBuilder(this, AppDatabase::class.java, "your_db")
        .addMigrations(MIGRATION_1_2).build()
