c# - Send data through Wifi from C# to Java

Question

I'm trying to communicate a Windows (C#) software with an Android (Java) application. But Windows is throwing me the following error:

No connection could be made because the target machine actively refused it 192.168.1.3:8222

Windows code (C#)

Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
    void button1_Click(object sender, EventArgs e)
    {
        try
        {
            if (!clientSocket.Connected)
                clientSocket.Connect(IPAddress.Parse("192.168.1.3"), 8222); //This is my android ip address

            clientSocket.Send(Encoding.UTF8.GetBytes("Esto es una prueba"));
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

Android code (Java)

    localIPAddr = Utils.getIPAddress(true);// = getLocalIPAddress();

    // Toast.makeText(getApplicationContext(), localIPAddr,
    // Toast.LENGTH_SHORT).show();

    texto.setText(localIPAddr);

    Log.d("Test", localIPAddr);

    new Thread(new Runnable() {
        public void run() {

            while (true) {
                try {
                    if (serverSocket == null) {
                        // No need to get local IP address and to bind InetSocketAddress.
                        // Following single line make it very simple.
                        serverSocket = new ServerSocket(8222, 4);
                        workerSocket = serverSocket.accept();

                        Log.d("Test", "serverSocket == null");

                    }
                    // When data are accepted socketInputStream will be invoked.
                    socketInputStream = new DataInputStream(
                                workerSocket.getInputStream());

                    /* Since data are accepted as byte, all of them will be collected in the
                    following byte array which initialised with accepted data length. */
                    byte[] rvdMsgByte = new byte[socketInputStream.available()];

                    Log.d("Test", "rvdMsgByte: "+rvdMsgByte);

                    // Collecting data into byte array
                    for (int i = 0; i < rvdMsgByte.length; i++)
                        rvdMsgByte[i] = socketInputStream.readByte();

                    // Converting collected data in byte array into String.
                    String rvdMsgTxt = new String(rvdMsgByte);

                    // Setting String to the text view.
                    texto.setText(rvdMsgTxt);
                } catch (Exception ex) {
                }
            }
        }
    });

Maniofest permissions

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Why it says the target machine actively refused it? What am I doing wrong?

EDIT:

Ok I solved the issue of it not connecting. I forgot to add .start(); at the end of the Android Thread so the thread was never executed. But now I'm receiving bytes but no text. Here's the logcat:

好的，我解决了。我很愚蠢。这是工作代码：

窗口 (C#)

Socket clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
    void button1_Click(object sender, EventArgs e)
    {
        try
        {
            if (!clientSocket.Connected)
                clientSocket.Connect(IPAddress.Parse("192.168.1.3"), 8222);

            clientSocket.Send(Encoding.UTF8.GetBytes("Esto es una prueba"));
            clientSocket.Disconnect(true);
            clientSocket.Close();
            clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            //You need to close the send code
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

安卓 (Java)

private void runTcpServer() {
    ServerSocket ss = null;
    try {
        ss = new ServerSocket(TCP_SERVER_PORT);
        Log.d("TcpServer", ss.getInetAddress()+"");
        //ss.setSoTimeout(10000);
        //accept connections
        Socket s = ss.accept();
        Log.i("TcpServer", "Receiving");
        BufferedReader in = new BufferedReader(new InputStreamReader(s.getInputStream()));
        //BufferedWriter out = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
        //receive a message
        Log.i("TcpServer", in.readLine());
        final String incomingMsg = in.readLine() + System.getProperty("line.separator");
        Log.i("TcpServer", "received: " + incomingMsg);
        runOnUiThread(new Runnable() {
            public void run() {
                texto.append("received: " + incomingMsg);
            }
        });

        s.close();
    } catch (InterruptedIOException e) {
        //if timeout occurs
        e.printStackTrace();
        Log.e("TcpServer", ""+e);
    } catch (IOException e) {
        e.printStackTrace();
        Log.e("TcpServer", ""+e);
    } finally {
        if (ss != null) {
            try {
                ss.close();
            } catch (IOException e) {
                e.printStackTrace();
                Log.e("TcpServer", ""+e);
            }
        }
    }
}
