/**
 * 处理接受到的消息
 */
private void receiveMessage() {
    while (isThreadRunning) {
        try {
            if (client != null) {
                client.receive(receivePacket);
            }
            lastReceiveTime = System.currentTimeMillis();
            Log.d(TAG, "receive packet success...");
        } catch (IOException e) {
            Log.e(TAG, "UDP数据包接收失败！线程停止");
            stopUDPSocket();
            e.printStackTrace();
            return;
        }

跑起来项目发送是成功的 但是接收从来没收到过消息 请教下这个情况是？
