use this method in an IABHelper:
List<String> moreSkus = new ArrayList<String>(); moreSkus.add("sku1"); moreSkus.add("sku2"); mHelper.queryInventoryAsync(true, moreSkus, mGotInventoryListener);
I test that it works fine, you can add inapp or sub type sku to the list and return all data to invenroty
