WebSocket supported in Android Stock Browser or not?

using https://github.com/einaros/ws

Server:

var WebSocketServer=require('ws').Server,wss=new WebSocketServer({port:8004});

wss.on('connection',function(s) {
    s.on('message',function(_){console.log('received: '+_);});
});

Client:

var s=new WebSocket('ws://mysite.com:8004');
//android default browser dies here <---------------?       
s.onopen=function(){
    $('body').css({'background':'green'});
    s.send('hi');
    };

I have to ask why android default browser does not open the connection?

I visit www.websocket.org/echo.html on the default android browser and it says This browser supports websocket. so what is the problem?

This simple code works on iphone safari, windows chrome, android mobile chrome no problem.

On android default browser I can also console.dir(window.WebSocket); and it shows the WebSocket Object no differently than other browsers.

If someone knows why, please tell.

Thanks

UPDATE

if (!window.WebSocket && window.MozWebSocket) {
    window.WebSocket = window.MozWebSocket;
    alert('MozWebSocket');
}
else if (!window.WebSocket) {
    alert("WebSocket not supported by this browser");
}
else{
    alert('wtf!? '+window.WebSocket);
}

This gives me a console log of:

wtf!? function WebSocket(){[native code]}
