OkHttp Async call returning JsonArray Null

Question

I declared a global JSONArray variable to return in okHttpCallback function but it returns null. I am getting data,But while returning it is null

JSONArray jsonArray; //Global in class

public JSONArray getJsonString(String link){

            okHttpClient.newCall(request).enqueue(new Callback() {

                @Override
                public void onResponse(@NotNull Call call, @NotNull Response response) throws IOException {

                    if(response.isSuccessful()){
                        try {

                            jsonArray = new JSONArray(response.body().string());

                        }catch (JSONException e){
                            e.printStackTrace();
                        }

                    }else{
                        Log.d("ERROR", "onResponse: ERROR" + response.body().string());
                    }
                }
            });


       return jsonArray; // Null Here

    }

Actually the network call is taking place in another thread and you are returning jsonArray in main thread. You should return jsonArray only when you get response through okhttp. You should do as follows :-

public void getJsonResponse(String link){

            okHttpClient.newCall(request).enqueue(new Callback() {

                @Override
                public void onResponse(@NotNull Call call, @NotNull Response response) throws IOException {

                    if(response.isSuccessful()){
                        try {

                            jsonArray = new JSONArray(response.body().string());
                            getJsonString(jsonArray);

                        }catch (JSONException e){
                            e.printStackTrace();
                        }

                    }else{
                        Log.d("ERROR", "onResponse: ERROR" + response.body().string());
                    }
                }
            });


    }

  // somewhere in class 

public JSONArray getJsonString(JSONArray jsonArr)
{
   return jsonArr;
}
