Gottox socket.io-java-client“握手时出错引起：java.io.FileNotFoundException：http：//192.168.1.69：8080 / socket

Question

我试图与我的android应用程序沟通简单的节点js（socket.io）服务器我使用Gottox socket.io-java-client lib转换为jar文件作为客户端但它总是返回错误（错误，而握手文件未找到）我在我的移动设备上测试应用程序在本地网络上使用wifi我的IP是192.168.1.69我已经通过网络测试了服务器通信它工作正常

节点js套接字服务器的代码

var mongo = require('mongodb').MongoClient,
    Client = require('socket.io').listen(8080).sockets;
    mongo.connect('mongodb://192.168.1.69/chat',function(err, db){
            if(err) throw err;
            Client.on('connection',function(socket){
                    //get mongo db collection
                    console.log("Connected to server");
                    var col = db.collection("messages"),
                    sendStatus = function(s){

                        };
                    //emit all messages
                    col.find().limit(100).sort({_id:1}).toArray(function(err, res){
