我正在尝试在我的 android 设备上对 ZeroMQ 进行编程，并且我知道如何使用 ZeroMQ（来自 C++、Php、.Net，我一直在使用它。）如果我列出我到目前为止所做的事情：
- 从 Android Studio 的依赖项中，我从 maven 中央搜索添加了org.zeromq:jeromq:0.3.5 。
- 之后，我输入了如下代码：
try
{
ZMQ.Context context = ZMQ.context(1);
// Socket to talk to server
System.out.println("Connecting to hello world server...");
ZMQ.Socket requester = context.socket(ZMQ.REQ);
requester.connect("tcp://192.168.2.127:5555");
for (int requestNbr = 0; requestNbr != 10; requestNbr++) {
String request = "Hello";
System.out.println("Sending Hello " + requestNbr);
requester.send(request.getBytes(), 0);
byte[] reply = requester.recv(0);
System.out.println("Received " + new String(reply) + " " + requestNbr);
}
requester.close();
context.term();
}
catch (Exception e)
{
Log.e("Error", "Exception : " + e.getMessage());
}
当我运行它时，我遇到了如下异常：

我实际上并不是编程新手，而是 Android/Java 方面的新手。我无法弄清楚如何解决这个问题。我在互联网上搜索但找不到任何东西。
如果你能帮助我，我会很高兴。
提前致谢。
（另外，我忘了包括这个：）
