first of all.. i'm really sorry.. my english not very well..
i attach image my problem...

i'm use example from gamefaroq(thank's bro)

this TCP server :
import java.net.ServerSocket;
import java.net.Socket;
import java.io.*;
public class TCPDesktopServer implements Runnable{

public static final String SERVERIP = "127.0.0.1";
public static final int SERVERPORT = 1234;

public void run() {
try {
System.out.println("TCP S: Connecting...");

ServerSocket serverSocket = new ServerSocket(SERVERPORT);
while (true) {
Socket client = serverSocket.accept();
System.out.println("TCP S: Receiving...");
try {
BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()));
String str = in.readLine();
System.out.println("TCP S: Received: '" + str + "'");
} catch(Exception e) {
System.out.println("TCP S: Error");
} finally {
client.close();
System.out.println("TCP S: Done.");
}

}

} catch (Exception e) {
System.out.println("TCP S: Error");
}
}


public static void main (String a[]) {
new Thread(new TCPDesktopServer()).start() ;
}
}

the client :
package Socket.Test;

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

import android.util.Log;

public class TCPClient implements Runnable {
Socket TCPServer = new Socket();
@Override
public void run() {
try {

InetAddress serverAddr = InetAddress.getByName("127.0.0.1");//TCPServer.SERVERIP

Log.d("TCP", "C: Connecting...");
;
Socket socket = new Socket(serverAddr, TCPServer.getPort());
String message = "Hello from Client";
try {
Log.d("TCP", "C: Sending: '" + message + "'");
PrintWriter out = new PrintWriter( new BufferedWriter( new OutputStreamWriter(socket.getOutputStream())),true);

out.println(message);
Log.d("TCP", "C: Sent.");
Log.d("TCP", "C: Done.");

} catch(Exception e) {
Log.e("TCP", "S: Error", e);
} finally {
socket.close();
}
} catch (Exception e) {
Log.e("TCP", "C: Error", e);
}
}

}

package Socket.Test;

import android.app.Activity;
import android.os.Bundle;

import android.app.Activity;
import android.os.Bundle;

public class SocketTest extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);

// Thread sThread = new Thread(new UDPServer());
// Thread cThread = new Thread(new UDPClient());
// Thread sThread = new Thread(new TCPServer());
Thread cThread = new Thread(new TCPClient());

/*sThread.start();
try {
Thread.sleep(1000);
} catch (InterruptedException e) { }*/

cThread.start();

}
}


the manifest :
<?xml version="1.0" encoding="utf-8" ?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="Socket.Test" android:versionCode="1" android:versionName="1.0.0">
