android app(cordova)是否支持socket.io client

需要使用这里的插件：
https://github.com/Automattic/socket.io/issues/1204
https://github.com/mkuklis/phonegap-websocket
https://bitbucket.org/mkuklis/phonegap-websocket-demo

不幸的是这个插件不能直接在worklight6.1中使用
这里有人提相同的问题。
（尽管worklight6.1是基于cordova3.1做的封装<==通过在js中alert(device.cordova)中可以直接看出来），但是在worklight中不能直接使用cordova的插件，这点很不爽）

以下代码在android上打印出ReferenceError: io is not defined，mobile app到底是否支持socket.io client

$(document).on("pageinit","#chatroomPage",function(res){
	console.log("chatroom page init.");
	try{
		var socket = io.connect('http://192.168.1.101:3000');
		socket.on('connect', function(data) {
			console.log("connected to chat server.");
			socket.on('chat message',function(msg){
				$("#incomingMessages").append("<div class='message'><span class='username'>" 
						+ msg.user + ":</span> " + msg.msg + "</div>");
		        $("#incomingMessages").scrollTop($("#incomingMessages")[0].scrollHeight);
			});
		});
		
		socket.on('error', function(data) {
			console.log("error connect to chat server.");
		});
		socket.on('disconnect', function(data) {
			console.log("you are disconnected from chat server.");
		});
		
		$('#btnSend').bind('click',function(){
			socket.emit('chat message', {user:loginUser,msg:$('#m').val()});
			$('#m').val('');
			return false;
	        });
		
	} catch (e){
		navigator.notification.alert("socket.io error:" + e);
		console.log("socket.io error:", e);
	}
});

而在simulator上正常
