==>> 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.
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.

This data is of just one user. I have 50 of them.
I am still in learning stage and what I have done is that I have successfully listed all user in an activity. Now what I want to do is when I click on a user it should show it's related details in next activity...
List Users->Select Users->Show selected user details
I still don't know how to send data to other activity and display it.
I have a json response that looks somewhat like this.

There is a many to many relationship between users and groups.
I am using retrofit with the GsonConverterFactory. On response, how can I parse this information into objects?
I tried making a User class , and a group class, then I put an array of groups as a member of the user class.
But when I access User.getGroups().get(1).getID , it returns 0.
However, User.getGroups().size() does return 4 (the correct number in this case)
How can I achieve this in retrofit?
A practical tool to parse JSON correctly with retrofit can be to generate the classes with http://www.jsonschema2pojo.org
You just have to put the example JSON, the resource type in JSON and put the desired annotation style (GSON, Jackson, ..).
Finally click on the preview button and you can see the results

You have to parse the json response and store the different categories in different arraylist and based on the user selection of your render position you can use the selected arraylist.
You can do this by parsing the json response like this
JSONObject jsonObject = new JSONObject(response); // response is the json string that you are gettting from server
JSONArray jsonArray = jsonObject.getJSONObject("product_categories");
ArrayList<Categorydisplay> catDisList = new ArrayList<>();
ArrayList<Defaultdisplay> defaultDisList = new ArrayList<>();
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject = jsonArray.getJSONObject(i);
SomeModel someModel = new SomeModel();
if (jsonObject.has("id")) {
someModel.setId(jsonObject.getString("id"));
}
if (jsonObject.has("name")) {
someModel.setName(jsonObject.getString("name"));
}
so on.....
if(someModel.getDisplay().equals("default")){
defaultDisList.add(someModel);
}else{
catDisList.add(someModel);
}
}

You're parsing the initial string as an array. It isn't an array, its an object that contains a single array named "data". You need to parse it into a JSONObject, then get the array named data from it, then loop like you do.
try {
JSONArray articlesArray = new JSONObject(jString).getJSONArray("data");
JSONObject aObject;
for(int i=0; i<articlesArray.length(); i++){
aObject=articlesArray.getJSONObject(i);
SearchTrack a=new SearchTrack();
a.setId(aObject.getString("id"));
a.setLink(aObject.getString("link"));
a.setName(aObject.getString("name"));
a.setPicture(aObject.getString("picture"));
a.setNbAlbum(aObject.getString("nb_album"));
a.setNbFan(aObject.getString("nb_fan"));
a.setRadio(aObject.getString("radio"));
a.setType(aObject.getString("type"));
articles.add(a);
}
}catch (JSONException e) {
e.printStackTrace();
}

when I parsing this json object, String key "likes" is sometimes exist and sometimes do not exist in "data" jsonArray. So when I parsing JsonString "likes", sometimes I gets JSONException since I am parsing null value. Is there any way to skipping "null" json value?
Please help me regarding this.
if try catch it, next processes will be skipped.
you can check by isNull("name") method.
Edit: this is to check key. since you mentioned key exists sometimes. did you mean the value?
use JSONObjects method has(key)
data = (JSONObject) new JSONTokener(jsonObjRecv.toString()).nextValue();
if data.has("like"){
...
}
to check whether the value is null check with isNull("name")
