code: public static EventHandlerWrapper wrapEventHandler(@NonNull Object subscriber, @NonNull JSONObject jsonObject) {
          String type = jsonObject.optString("type");
          if (TextUtils.isEmpty(type)) {
              return null;
          }
          String producer = jsonObject.optString("producer");
  //        String subscriber = jsonObject.optString("subscriber");
          String action = jsonObject.optString("action");
          return new EventHandlerWrapper(type, producer, subscriber, action);
      }
docs: This performs the same feature as {@link #wrapEventHandler(String, String, Object, String)}, just parse the params from jsonObject.
  @param subscriber Original subscriber object
  @param jsonObject Json params
  @return An EventHandlerWrapper wrapping a subscriber and used to registered into event bus.
