TCP socket between C# server and Android Client

Question

Hi everybody,
I'm trying to write code to communicate between c# server and Android client by using TCP socket, I'm using below code but it dosn't work :(

Please please please help me...

C# Server Code:

TcpListener tcpListener = new TcpListener(sampleTcpPort);
                while (true)
                {
                    tcpListener.Start();
                    //Program blocks on Accept() until a client connects.
                    Socket soTcp = tcpListener.AcceptSocket();
                    Console.WriteLine("SampleClient is connected through TCP.");
                    Byte[] received = new Byte[1024];
                    int bytesReceived = soTcp.Receive(received, received.Length, 0);
                    String dataReceived = System.Text.Encoding.ASCII.GetString(received);
                    Console.WriteLine(dataReceived);
                    String returningString = "The Server got your message through TCP: " + dataReceived;
                    Byte[] returningByte = System.Text.Encoding.ASCII.GetBytes(returningString.ToCharArray());
                    //Returning a confirmation string back to the client.
                    soTcp.Send(returningByte, returningByte.Length, 0);
                    tcpListener.Stop();
                }

Android Client Code:

class testClass 
{
	private String serverIpAddress = "127.0.0.1";	
	public String results="";	
	public testClass()
	{
	    Thread cThread = new Thread(new   ClientThread());
            cThread.start();
	}
	
	
	public class ClientThread implements Runnable 
	{
	    public void run() 
	    {
	        try 
	        {
	            InetAddress serverAddr = InetAddress.getByName(serverIpAddress);
	            Log.d("ClientActivity", "C: Connecting...");	            
	            while (true) 
	            {
	        	results="";
	                try 
	                {
	                    Socket socket = new Socket("localhost", 4567);
	                    BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
	                    BufferedWriter out = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
	                    out.write("Test");
	                    out.flush();
	                    String inMsg = "";
	                    boolean b=false;
	                    while (!b)
	                    {
	                       inMsg = in.readLine();
	                       if(inMsg!="")
	                    	   b=true;
	                    }
	    	            socket.close();
	    	            Log.d("ClientActivity", "C: Closed.");
	                } catch (Exception e) {Log.e("ClientActivity", "S: Error", e);}
	            }
	        } 
	        catch (Exception e) { Log.e("ClientActivity", "C: Error", e);}
	    }
	}
