How to get categories of an item

Hi there!
I'm trying to get the categories of each item in an order and having troubles with that using the latest Android SDK.

I am fetching the order via the OrderConnector and noticed that each item has pretty much all I need but the categories: so I ended up asking each item details via the InventoryConnector, but still get an empty categories list.

orderConnector.getOrder(orderId)
inventoryConnector.getItem(itemId)

Is there anything wrong with this approach?

The workaround was to call

inventoryConnector.getItemWithCategories(itemId)

instead of

inventoryConnector.getItem(itemId)

otherwise the categories array is not getting populated at all.

Do not trust the accepted answer.

.getCategories() would have to be applied to retrieve the categories for an item.

getCategories

public java.util.List<Category> getCategories()
Categories associated with this item

Hi @Jonathan Ryan Grice, unfortunately I can't find your answer useful as of now.

I am calling getCategories() on the Item instance fetched via either the OrderConnector or InventoryConnector but the list is empty.

For instance, using Kotlin:

val item = inventoryConnector.getItem("my item id")
item.categories // empty

Is there any way to tell the SDK to also fetch the categories, like in a GraphQL fashion?

To give you a better understanding here's an example of an item I have in the inventory.

Item: Large Beer

Categories: Drinks, ...

Tags: Alcohol, ...

I can read all the item properties (e.g. the tags) but not the categories.

It's worth noting that the categories array is null and hasCategories always returns false, while on items with no tags I always get a non null list (empty or with some tags) and hasTags always returns true. Sounds like a serialization/deserialization issue on the SDK itself?

Thanks for your help.

getCategories is a function, not an object.

It's a function, meaning it will call getCagegories() on the Java code. Added my answer with the real solution. Thank you anyway!
