Special Category Ads - new behaviour in 7.0

[NenadP]

Campaign.java

  @Facebook("special_ad_category")
  private String specialAdCategory;

needs to change or we need additional one like

  @Facebook("special_ad_categories")
  private List<String> specialAdCategories;

Special Ad Category
This change applies to v7.0+.

The special_ad_category parameter on the POST /act_<AD_ACCOUNT_ID>/campaigns endpoint has been deprecated and replaced with a new special_ad_categories parameter.

The new special_ad_categories parameter is required and accepts an array. If you get the special_ad_category parameter, it will still return a string, but you should use GET /{campaign-id}?fields=special_ad_categories to get an array back.

So, for example, I've published one of my campaigns (thru restFb), and I was (obviously) able to send special_ad_categories as required from Facebook when creating, but I am unable to retrieve it back when reading (using provided DTO's).

For my example, querying campaign using graph api, it will return something like:

{
  "special_ad_categories": [
    "HOUSING",
    "CREDIT",
    "EMPLOYMENT"
  ],
  "special_ad_category": "HOUSING",
  "id": "<CAMPAIGN_ID>"
}

As you can see, existing special_ad_category will not have complete detail.
