How to make a HTTP/POST request in Kotlin (Android) to simple server?

Question

Hello I am trying to begin an Android app in Kotlin. I have been trying to find a way to simply send and receive data from an android app to a simple HTTP server I made on my computer. The idea I am hoping is just make an app with a text box on it and a send button. When I press the send button it sends it to the simple http server (whether I use IP address or URL isn't Important)

This is just simply a proof of concept that I can make my own simple HTTP Server and get the app to send and receive from it.

I am essentially trying to do a server-client architecture between an android app and a computer. I can get this concept to work between two computer applications (python, java, C++ etc) but not how to do it in android. I keep looking for other answers on here but still come up short.

to be specific do I need enable certain features within the configurations file or a library that will allow the task to be done in the background?

Thank you for your help in advance.

If you want to connect of server for sending requests (POST and GET) then follow this code

    public void callApi(String urls,String calledFor) {
        
    
    try {
            HttpGet httppost = new HttpGet(urls);
            HttpClient httpclient = new DefaultHttpClient();
            HttpResponse response = httpclient.execute(httppost);
    
            int status = response.getStatusLine().getStatusCode();
    
            if (status == 200) {
                HttpEntity entity = response.getEntity();
                String data = EntityUtils.toString(entity);
                JSONObject jsono = new JSONObject(data);
                JSONObject json = jsono.getJSONObject("data");
    
            }
    
        } catch (ParseException e1) {
            e1.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }
 }
