我想将多个Android模拟器客户端连接到Android模拟器服务器。我正在使用this post中的代码，我已经更改了服务器。当只有一个客户端尝试连接时，代码工作得很好。当我尝试将两个客户端连接到服务器时，第二个客户端的消息似乎没有通过。
我想知道我需要做些什么来实现这个目标？我是否需要重定向其他端口，或者代码中是否缺少某些内容？
logcat一遍又一遍地报告以下内容，它被卡在循环中。一旦启动第一个客户端，它就会立即显示此错误：

这是客户端（与其他帖子相同）：
public class ClassAidClient4Activity extends Activity {
private Button bt;
private TextView tv;
private Socket socket;
private String serverIpAddress = "10.0.2.2";
// private String serverIpAddress = "192.168.1.102";
// AND THAT'S MY DEV'T MACHINE WHERE PACKETS TO
// PORT 5000 GET REDIRECTED TO THE SERVER EMULATOR'S
// PORT 6000
private static final int REDIRECTED_SERVERPORT = 5000;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
bt = (Button) findViewById(R.id.button1);
tv = (TextView) findViewById(R.id.textView1);
try {
InetAddress serverAddr = InetAddress.getByName(serverIpAddress);
socket = new Socket(serverAddr, REDIRECTED_SERVERPORT);
} catch (UnknownHostException e1) {
e1.printStackTrace();
} catch (IOException e1) {
e1.printStackTrace();
}
bt.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
try {
EditText et = (EditText) findViewById(R.id.editText1);
String str = et.getText().toString();
PrintWriter out = new PrintWriter(new BufferedWriter(
new OutputStreamWriter(socket.getOutputStream())),
true);
out.println(str);
Log.d("Client", "Client sent message");
} catch (UnknownHostException e) {
tv.setText("Error1");
e.printStackTrace();
} catch (IOException e) {
tv.setText("Error2");
e.printStackTrace();
} catch (Exception e) {
tv.setText("Error3");
e.printStackTrace();
}
}
});
}
}
这是服务器（从其他帖子稍微改了一下）：
public class ClassAidServer4Activity extends Activity {
ServerSocket ss = null;
String mClientMsg = "";
Thread myCommsThread = null;
protected static final int MSG_ID = 0x1337;
public static final int SERVERPORT = 6000;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView tv = (TextView) findViewById(R.id.textView1);
tv.setText("Nothing from client yet");
this.myCommsThread = new Thread(new CommsThread());
this.myCommsThread.start();
}
@Override
protected void onStop() {
super.onStop();
try {
// make sure you close the socket upon exiting
ss.close();
} catch (IOException e) {
e.printStackTrace();
}
}
Handler myUpdateHandler = new Handler() {
public void handleMessage(Message msg) {
switch (msg.what) {
case MSG_ID:
TextView tv = (TextView) findViewById(R.id.textView1);
tv.setText(mClientMsg);
break;
default:
break;
}
super.handleMessage(msg);
}
};
class CommsThread implements Runnable {
public void run() {
// Socket s = null;
while(true) {
try {
ss = new ServerSocket(SERVERPORT );
Socket socket = ss.accept();
Thread lThread = new Thread(new ListeningThread(socket));
lThread.start();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
class ListeningThread implements Runnable {
private Socket s = null;
public ListeningThread(Socket socket) {
// TODO Auto-generated constructor stub
this.s = socket;
}
@Override
public void run() {
// TODO Auto-generated method stub
while (!Thread.currentThread().isInterrupted()) {
Message m = new Message();
m.what = MSG_ID;
try {
if (s == null)
s = ss.accept();
BufferedReader input = new BufferedReader(
new InputStreamReader(s.getInputStream()));
String st = null;
st = input.readLine();
mClientMsg = st;
myUpdateHandler.sendMessage(m);
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
}

我发现了我的问题。
ss = new ServerSocket(SERVERPORT );需要在while循环之外。
如果有人发现任何其他问题，请告诉我。感谢
class CommsThread implements Runnable {
public void run() {
// Socket s = null;
ss = new ServerSocket(SERVERPORT );
while(true) {
try {
Socket socket = ss.accept();
Thread lThread = new Thread(new ListeningThread(socket));
lThread.start();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}

我使用ThreadPool为多个客户端（即不同的模拟器）连接到单个服务器。它运作得很好。
