android socket连接不上

安卓客户端向pc服务器发一个字符串，怎么都连接不上，求大神指导一下。
服务器端代码：
import java.io.DataInputStream;
public class server {
public static void main(String[] args) {
try{

ServerSocket ss = new ServerSocket(10457);

InetAddress ipAddress = InetAddress.getLocalHost();

Socket socket = ss.accept();

DataInputStream dis = new DataInputStream(socket.getInputStream());
String msg = dis.readUTF();
System.out.println(msg);

}catch(Exception e){
e.printStackTrace();
};

}

}
android客户端代码：
package chen.button;

public class ButtonActivity extends Activity {
public Button button1;
String result = "123";

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
button1 =(Button) findViewById(R.id.button1);
button1.setOnClickListener(new Startsocketlistener());
}
class Startsocketlistener implements OnClickListener{

public void onClick(View v) {

new ServerThread().start();
button1.setText("123");

}
class ServerThread extends Thread{

public void run(){
Socket socket = null;
try{

InetAddress serverAddr = InetAddress.getByName("222.18.168.175");
socket = new Socket(serverAddr,10457);

DataOutputStream dos = new DataOutputStream(socket.getOutputStream());
dos.writeUTF(result);
dos.close();
socket.close();

}

}catch(IOException e)
{};
}
}

}

}
