Android client connecting to server on pc, using Java sockets

Question

I want to send a simple string to a server on my desktop PC. Here is what I have on my PC:

public static void main(String[] args) {
System.out.println("Server Started");
    Server server = new Server();
    server.start();
}

public void start(){
    try {
    ServerSocket SRVSOCK = new ServerSocket(333);
    Socket SOCK = SRVSOCK.accept();
    InputStreamReader ir = new InputStreamReader(SOCK.getInputStream());
    BufferedReader bf = new BufferedReader(ir);

    String MESSAGE = bf.readLine();
        System.out.println(MESSAGE);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();    
    }
}   

For my android tablet I have this in the onCreate() :

@Override
protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);  
   setContentView(R.layout.activity_main);
   Thread tthread = new Thread(new Runnable(){
       @Override
            public void run() {
                Connect();
            }});
    }

public void Connect(){      
    try {
        Socket SOCK = new Socket("10.0.0.3", 333);
        PrintWriter pw = new PrintWriter(SOCK.getOutputStream());
        pw.println("FROM ANDROID!");
     } catch (UnknownHostException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
     } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }                   
}

I have seen you can create a new thread which you need (otherwise the app UI freezes), but it still does not send the text to my server, I have added the incoming and outgoing port in my windows firewall, and even tried to turn off the firewall, but still no luck..

The android code is running on a real physical tablet (Nexus 7 2013) and not an emulator.

What is wrong here?

This whats in my log cat when the app is opened

Answer 1

You are declaring a Thread but you forgot to .start() it. So your code is not executed.
