==>> I am using the code below to get JSONArray:

Response response = client.newCall(request).execute();

 //here I am getting the json response(mentioned above) from wordpress rest api   

  String json = response.body().string(); 

  JSONObject object = new JSONObject(json);

//Below code is giving me null array as I dont have "Array name" in my json response.

  JSONArray array = object.optJSONArray("Name of Array in json response");

Please help me get JSONArray out of json response.

How can I attach my complete json response (from wordpress rest API) here to clarify my question in a better way. — Acwanshi

I have my json response in a proper formatted way but I am not able to paste here. You can run the below URL in REST Console (in chrome) to get better picture : realcake.in/wp-json/wp/v2/posts Please use GET request. — Acwanshi

Looking at your JSON string, it seems that the entire response body is a JSON-Array, so you can simply parse it directly into a instance of JSONArray. This is how you can do it:

//get your JSON body-string like you do
String json = response.body().string();
//parse it directly into JSONArray
JSONArray array = new JSONArray(json);
//do whatever you want with the array...

I hope this helps you.
