（Android）用Socket的小例子

1，建立 PORT 映射

? Android模拟器启动后，要运行下个命令。使得模拟器和主机的 PORT 映射上。

telnet 127.0.0.1 5554redir add tcp:8888:8888

2，放开权限

? 在 AndroidManifest.xml 中加入下面一句。

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

3，Android端的服务器程序片段如下。

? 全部例子可从 google code 得到。

    public void run() {        try {            serverSocket = new ServerSocket(8888, 1024);        }        catch (IOException e) {            e.printStackTrace();            return;        }        InputStream in;        while (!hasStopCmd) {            try {                client = serverSocket.accept();                in = client.getInputStream();            }            catch (IOException e) {                e.printStackTrace();                return;            }            BufferedReader p = new BufferedReader(new InputStreamReader(in));            while (!hasStopCmd) {                TouchSimEvent event = new TouchSimEvent();                try {                    String str = p.readLine();                    if (str == null) {                        break;                    }                    event.set(str);                }                catch (IOException e) {                    break;                }                for (TouchSimEventListener listener : listeners) {                    listener.onTouchSimEvent(event);                }            }        }    }

4，PC端的客户程序如下

        try {            serverAddr = InetAddress.getByName("127.0.0.1");            socket = new Socket(serverAddr, 8888);        }        catch (Exception e) {            e.printStackTrace();        }        TouchSimEvent event = new TouchSimEvent();        event.setX(x);        event.setY(y);        event.setClick(click);        try {            if (!socket.isConnected()) {                resetSocket();            }            PrintWriter p = new PrintWriter(socket.getOutputStream());            p.println(event.get());            p.flush();        }        catch (Exception e) {        }
