c# - ac＃サーバー（WinRT / Metro）とAndroidクライアントの間で通信する方法は？

Question

私はAndroidとC＃2012の間でTCPまたはHTTPを介して通信する方法を探しています。これが私がこれまでに持っているものです

JAVAクライアント：

package com.example.test;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.InetAddress;
import java.net.Socket;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends Activity {

    TextView tc;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button btn = (Button)this.findViewById(R.id.button1);
        tc = (TextView) this.findViewById(R.id.textView1);
        btn.setOnClickListener(new OnClickListener() {

            public void onClick(View arg0) {
                Thread th = new Thread(new Runnable() {

                    public void run() {
                        connect();
                    }

                });
                th.start();
            }

        });


    }


    private void connect() {

        InetAddress[] server;
        try {
            server = InetAddress.getAllByName("192.168.1.100");

            Socket socket = new Socket(server[0], 3975);

            if (socket.isConnected()){
                Log.d("connected", "connected");
            }

            PrintWriter w = null;
            BufferedReader r = null;

            w = new PrintWriter( new BufferedWriter( new OutputStreamWriter(socket.getOutputStream())),true); 
            r = new BufferedReader(new InputStreamReader(socket.getInputStream()));                

            w.println("test");
            /*String m = null;

            while ((m=r.readLine())!= null) {
                w.write(m,0,m.length());
                w.flush();
             }*/



        } catch (Exception e) {
            // TODO Auto-generated catch block
            Log.d("error", e.getMessage());
        }



    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
}

C＃サーバー：

public sealed partial class MainPage : Page
{
    public MainPage()
    {
        this.InitializeComponent();
    }

/// <summary>
/// Invoked when this page is about to be displayed in a Frame.
/// </summary>
/// <param name="e">Event data that describes how this page was reached.  The Parameter
/// property is typically used to configure the page.</param>
protected override void OnNavigatedTo(NavigationEventArgs e)
{

}

public async void ServiceButtonClick(object sender, RoutedEventArgs e)
{



    StreamSocketListener listener = new StreamSocketListener();
    listener.ConnectionReceived += OnConnection;

    try
    {
        await listener.BindServiceNameAsync("3975");
        lblMessage.Text = "We are listening for connections...";
    }
    catch (Exception ee)
    {
        lblMessage.Text = "Unable to bind service.. " + ee.Message;
    }
}

private async void OnConnection(StreamSocketListener sender, StreamSocketListenerConnectionReceivedEventArgs args)
{

    DataReader reader = new DataReader(args.Socket.InputStream);


    this.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () =>
    {
        lblMessage.Text = "We are connected to the client";
    });


    try
    {
        while (true)
        {
            uint sizeFieldCount = await reader.LoadAsync(sizeof(uint));
            if (sizeFieldCount != sizeof(uint))
            {
                this.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () =>
                {
                    lblMessage.Text = "the underlying socket was closed before we were able to read the whole data - 1";
                });
                return;
            }
            uint stringLength = reader.ReadUInt32();
            uint actualStringLength = await reader.LoadAsync(stringlength);
            if (stringLength != actualStringLength)
            {
                this.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () =>
                {
                    lblMessage.Text = "the underlying socket was closed before we were able to read the whole data - 2";
                });
                return;
            }

            string temp;
            temp = reader.ReadString(actualStringLength);

            this.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () =>
            {
                lblMessage.Text = "Client said - " + reader.ReadString(3);
            });

        }

    }
    catch (Exception e)
    {
        this.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () =>
        {
            lblMessage.Text = "ERROR: " + e.Message + " - " + e.Source + " - " + e.StackTrace;
        });
    }


}

}

これで、クライアントのボタンをクリックするとソケットが接続されますが、電話からC＃サーバーにデータを送信すると、サーバーに何も表示されません。受信側または送信側で間違っていることはありますか？TCP経由で基本的な文字列を送信しようとしています。
