Hello everyone,

According from : rest - How to make a synchronous call using Retrofit on Android - Stack Overflow[^]

if I use retrofit2 synchronously would make app crash, but I really need something that could return the value directly.

What I have tried:

I've ever used asycntask like this :

public static class GetData extends AsyncTask<Void, Void, String> {

        @Override
        protected String doInBackground(Void... vd) {
            RequestHandler requestHandler = new RequestHandler();

            HashMap<String, String> params = new HashMap<>();
            params.put("user_id", "1");
            return requestHandler.sendPostRequest(URLs.GET_VIDEOS, params);
        }

        @Override
        protected void onPostExecute(String vdata){
            super.onPostExecute(vdata);
        }
    }

this could be return value directly when I call :

new GetData().execute().get();

Note : I've ever used volley also, but volley incompatible with laravel, the result always GET never POST.

Q : Is there other solutions to get value data directly besides using asynctask?
I don't want to using asynctask because it caused my app slow.

Please someone help me

Thanks
