Here is a kotlin version if anybody needs it:

@Database(entities = [User::class], version = 1)
abstract class MyDatabase : RoomDatabase() {
    abstract fun myDao(): MyDao?
}

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

    public abstract MyDao myDao();
}

As your error message suggested you should extend RoomDatabase
