我正在开发一个使用TCP进行设备连接的Android应用程序.问题是我是套接字编程的新手.我已成功制作了服务器和客户端代码.每个客户端都可以连接到服务器,服务器可以回复客户端.但我似乎无法使服务器同时向所有连接的客户端发送消息.使服务器向客户端广播消息的步骤是什么？
这是服务器代码：

ServerSocket server = null;
try {
    server = new ServerSocket(9092); // start listening on the port
} catch (IOException e) {
    Log.d("btnCreate onClick","Could not listen on port: 9092");
}
Socket client = null;
while(true) {
    try {
        client = server.accept();
    } catch (IOException e) {
        Log.d("btnCreate onClick","Accept Failed");
    }
    //start a new thread to handle this client
    Thread t = new Thread(new ClientConn(client));
    t.start();
}

和服务器线程：

class ClientConn implements Runnable {
    private Socket client;

    ClientConn(Socket client) {
        this.client = client;
    }

    public void run() {
        BufferedReader in = null;
        PrintWriter out = null;
        try {
            /* obtain an input stream to this client ... */
            in = new BufferedReader(new InputStreamReader(
                        client.getInputStream()));
            /* ... and an output stream to the same client */
            out = new PrintWriter(client.getOutputStream(),true);
        } catch (IOException e) {
            e.printStackTrace();
            return;
        }

        String msg;
        try {
            while ((msg = in.readLine()) != null) {
                Log.d("ClientConn","Client says: " + msg);
                out.println(msg);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
