Client Exception when creating category using sdk

We are trying to create items and assign them to a new category using the sdk.
However we are having issues when creating a new category without a helpful error message 

Category newCategory = new Category();
newCategory.setName("TokenPrinter");
mInventoryConnector.createCategory(newCategory);

this throws a client exception: 
statusCode = UNKNOWN; 
statusMessage = null
if instead I use: 

Category newCategory = new Category();
mInventoryConnector.createCategory(newCategory);
this throws a client exception 
statusCode = 400; 
statusMessage = Invalid category:Name is required to be non-null

But as you can see from the first attempt providing a name does not resolve the issue and there is no follow up message.

Any Light you can shed on this would be appreciated.

I was able to reproduce your issue, and looking at the exception, it complains about the Category's Items being null.

I have filed a ticket for this, as ideally it should just create an empty ArrayList of Items for you, if you do not set one.

For now the workaround would be to create an empty ArrayList and pass it into the Category object. 

                Category newCategory = new Category();
                newCategory.setName("New Category");
                newCategory.setItems(new ArrayList<Reference>());
                mInventoryConnector.createCategory(newCategory);

Thanks Raymond, works a treat. When you say "looking at the exception, it complains about the category's items being null" could you elaborate on how/where you saw this exception? As Billy mentioned, we just got the 400 error "Invalid category:Nameis required to be non-null".

Great to hear it works! The null items exception was from using the first code snippet Bill provided:

Category newCategory = new Category();
newCategory.setName("TokenPrinter");
mInventoryConnector.createCategory(newCategory);

The exception shows up before the ClientException Bill mentioned:

07-16 14:42:15.287 1739-1921/? E/JavaBinder: *** Uncaught remote exception!  (Exceptions are not yet supported across processes.)
    android.database.sqlite.SQLiteConstraintException: category.items may not be NULL (code 19)
