android 使用socket与pc传递对象的问题

项目需要android与pc机实现自定义对象的传递，设计先将对象序列化然后通过tcp socket进行通信，目前emulator可以实现自发自收，但是pc向android emulator发送对象的时候抛出Eception，代码如下。望牛人指点，不胜感激
emulator上的tcp serverpackage client.tcp;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.ObjectInputStream;
import java.net.ServerSocket;
import java.net.Socket;

import android.util.Log;

public class TCPAndroidServer extends Thread {

public static final String SERVERIP = "localhost" ;
public static final int SERVERPORT = 5557 ;
public TcpClient TcpClient_;
public void run() {
try {
System.out.println( "S: Connecting..." );


while ( true ) {
ServerSocket serverSocket = new ServerSocket(SERVERPORT);
Socket client = serverSocket.accept();
System.out.println( "S: Receiving..." );

try {
InputStream ips = client.getInputStream();
ObjectInputStream ois = new ObjectInputStream(ips);
SetupParameter setupParameter_=new SetupParameter();
setupParameter_=(SetupParameter)ois.readObject();
String str = setupParameter_.getMessage();
System.out.println( "S: Received: '" + str + "'" );
serverSocket.close();
} catch (Exception e) {
System.out.println( "S: Error" );
e.printStackTrace();
} finally {
client.close();
System.out.println( "S: Done." );
}

}

} catch (Exception e) {
System.out.println( "S: Error" );
e.printStackTrace();
}
}
}复制代码emulator 上的tcp client
