How can I establish a communication between an android device an a python script?

I am trying to create an android app that communicates with a running python script. Both are connected to the same network and I want to send some text between them via sockets. I tryed to do it on multiple attempts but none of them worked. This is my current code :

python part:

import socket
import time

#Defines Server Values
listensocket = socket.socket()
Port = 8000
maxConnections = 999
IP = socket.gethostname() #Gets Hostname Of Current Macheine

listensocket.bind(("0.0.0.0",Port))

#Opens Server
listensocket.listen(maxConnections)
print("Server started at " + IP + " on port " + str(Port))

#Accepts Incoming Connection
(clientsocket, address) = listensocket.accept()
print("New connection made!")

running = True

#Main
while running:
    message = clientsocket.recv(1024).decode() #Receives Message
    if not message == "":
        print(message)
    # closes Server If Message Is Nothing (Client Terminated)
    else:
        clientsocket.close()
        running = False

android part :

class send extends AsyncTask<Void,Void,Void> {
    Socket s;
    PrintWriter pw;
    @Override
    protected Void doInBackground(Void...params){
        try {
            s = new Socket("0.0.0.0",8000);
            pw = new PrintWriter(s.getOutputStream());
            pw.write(message);
            pw.flush();
            pw.close();
            s.close();
        } catch (UnknownHostException e) {
            System.out.println("Fail");
            e.printStackTrace();
        } catch (IOException e) {
            System.out.println("Fail");
            e.printStackTrace();
        }
        return null;
    }
}
