Categories and subcategories with room
0
I need to store categories, which can have sub categories in database
public class Category {
public long id;
...
public List<Category> subcategories;
}
Something like graph.
How can this be done using room persistence library?
Big thanks!

Maybe you should add another table with foreign key to your class Category
