Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $

I'm getting a Json response from Flickr api which is like :

{
  "photos": {
    "page": 1,
    "pages": 1,
    "perpage": 100,
    "total": 2,
    "photo": [
      {
        "id": "14774811932",
        "owner": "32738276@N08",
        "secret": "cbb99f0039",
        "server": "3853",
        "farm": 4,
        "title": "Weltschmerz",
        "ispublic": 1,
        "isfriend": 0,
        "isfamily": 0,
        "date_faved": "1432471819"
      },
      {
        "id": "13274800365",
        "owner": "114920113@N07",
        "secret": "b652859e6a",
        "server": "3688",
        "farm": 4,
        "title": "cactus desert",
        "ispublic": 1,
        "isfriend": 0,
        "isfamily": 0,
        "date_faved": "1432466782"
      }
    ]
  },
  "stat": "ok"
}

and I need to get the two Photo objects in an ArrayList.

My code is:

Helper helper = new Helper(this);
    String jsonString = helper.loadJSONFromAsset();
    Gson gson = new Gson();
    Photos photos = gson.fromJson(jsonString,
                new TypeToken<Photos>() { }.getType());
   // ArrayList<Photo> photos = gson.fromJson(jsonString,
   //             new TypeToken<ArrayList<Photo>>(){}.getType());

Currently I load the file from assets. When this works I'll change it to the flickr api

Photo class :

public class Photos {
    Integer page;
    Integer pages;
    Integer perpage;
    Integer total;
    ArrayList<Photo> photos;
    String stat;


//getters and setters here

My understanding is that I have first to extract the photos item and then from that item to extract the Array photo so I can get the ArrayList I need.

I think you had to create the Gson TypeToken like this:

public class Photos {
   Integer page;
   Integer pages;
   Integer perpage;
   Integer total;
   ArrayList<Photo> photo;
   String stat;

   //setters and getters

}

In this way you could replicate the Flickr JSON and Gson will map the Json correctly with:

 Photos photos = gson.fromJson(jsonString,
            new TypeToken<Photos>(){}.getType());

then you can get your photos ArrayList with:

 photos.getPhoto();
