How to parse object which is sometimes Json object and sometimes json Array

Question

I working with API in which an object can an be array or it can be any object and I don't know in which scenario it will be object or array so i can't use different object base on some condition.

Unfortunately I've no access to API code so I can't do any changes there. Any trick that I've to do will be on client side.

So what is the best way to handle that scenario.

Edit : Response Example

.
.
  "ecf":"0",
            "place":{  },
            "mn":"1st Test",
            "teams":[  ],
            "past_ings":[  
               {  
                  "s":{  },
                  "d":{  
                     "a":{  
                        "t":{  
                           "i":"5221",
                           "a":"3",
                           "c":"not out",
                           "dt":null,
                           "fd":"0",
                           "bd":"0",
                           "cb":"no",
                           "b":"1",
                           "r":"0",
                           "sr":"0",
                           "four":"0",
                           "six":"0",
                           "name":"Umesh Yadav"
                        }
                     }
                  }
               }
.

The object t can be array or it can be object.

Note : I'm using Gson for parsing and using Retrofit in my network layer.

Object response = json.get("response")
if (response instanceof JSONArray) {
  // It's an array, cast it as a JSONArray to use it.
} else {
  // It's an object, cast it as a JSONObject to use it.
}

I'm not doing manual parsion. I'm using Gson and retrofit in my network layer

In that case, can't you just tell Retrofit to expect an Object and then do the check? I'm not that familiar with Retrofit, I'll read up on it.

Just define this is Object when parse json by Gson in Java. After that you have manual if then object is array or object.
