在Retrofit GET请求之后如何使用GSON解析此JSON响应？

我正在尝试在Retrofit GET请求之后使用GSON解析JSON响应 . 我不需要所有的键和值，所以我只是@Expose我需要的那些并指示解析器这样做 . 请求激活并且响应变得干净，但是查看logcat我发现这个错误，这显然表明POJO模型格式化或实现不好：

04-09 12:16:01.679 5604-5604/? V/Retrofit error﹕ retrofit.converter.ConversionException: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $

这是JSON响应（在GET请求后返回ok）：

    limit: 2,
    offset: 0
    }
}

这是对Retrofit服务的主要活动调用：

Map<String, String> params = new HashMap<String, String>();
    params.put("city_id", "2621");
    params.put("offset", "0");
    params.put("limit", "2"); 
    params.put("category", "topPicks");
    params.put("format", "json");


    ApiClient.getApiClient().listVenues(params, new Callback<List<ApiResponse>>() {

        @Override
        public void success(List<ApiResponse> venues, Response response) {

            //consumir venues
            Log.v("RETROFIT SUCCESS", response.getBody().toString());

            mAdapter = new MainCustomAdapter(venues);
            mRecyclerView.setAdapter(mAdapter);

        }

        @Override
        public void failure(RetrofitError retrofitError) {

            if (retrofitError.getResponse() != null) {
                Log.v("Retrofit error", retrofitError.getCause().toString());
            }
            //manejar el fallo


        }
    });

这是Api客户端：

public class ApiClient {
private static ApiVenuesInterface apiVenues;

public static ApiVenuesInterface getApiClient() {

   Gson gson = new GsonBuilder().excludeFieldsWithoutExposeAnnotation().create();

    if (apiVenues == null) {
        RestAdapter restAdapter = new RestAdapter.Builder()

                .setEndpoint("http://endpoint.com")
                .setConverter(new GsonConverter(gson))
                .setLogLevel(RestAdapter.LogLevel.FULL).setLog(new AndroidLog("RETROFIT"))
                .build();

        apiVenues = restAdapter.create(ApiVenuesInterface.class);
    }

    return apiVenues;
}

 public interface ApiVenuesInterface {
     //llamada asíncrona al querystring de venues
     @GET("/api/v1/venues")
     void listVenues(@QueryMap Map<String, String> params, Callback<List<ApiResponse>> callback);
}}

最后这是我的POJO模型（我认为是主要问题的地方）：

public class ApiResponse {
    private List<Object> objects = new ArrayList<Object>();

}
class Object {

    @Expose
    private String name;
    @Expose
    private List<String> photos = new ArrayList<String>();
    @Expose
    private String address;
    @Expose
    private List<Category> categories = new ArrayList<Category>();

    /**
     *
     * @return
     * The name
     */
    public String getName() {
        return name;
    }


    /**
     *
     * @return
     * The photos
     */
    public List<String> getPhotos() {
        return photos;
    }

    /**
     *
     * @return
     * The address
     */
    public String getAddress() {
        return address;
    }

    /**
     *
     * @return
     * The categories
     */
    public List<Category> getCategories() {
        return categories;
    }

    class Category {
        @Expose
        private String name;

        /**
         *
         * @return
         * The name
         */
        public String getName() {
            return name;
        }

    }}

那么，我怎么必须建模我的POJO来解析我需要的数据呢？提前致谢 .

IMPORTANT EDIT: This question is valid for Retrofit 1.x. Be aware that Retrofit 2.x is a little bit different than this because it uses annotations and Call methods.
