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

Sorry, Room doesn't support auto-creation of tables without data loss.

It is mandatory to write the migration. Otherwise, it'll erase all the data and create the new table structure.
