Android : Node.js http chat server

I try create chat server, which will be conncted to Android clients. 1 Client send some data on server, server receive it and send to rest of Clients. So I tried use 'net', but that didn't works. On server i'm listening 1490 port and 192.168.3.XX address. Now my Clients can connect to server, but sending data doesn't work. Code:

var net = require('http');
var sockets = [];
var tcpServer = net.createServer();

tcpServer.on('connection', function(socket){
console.log(socket.remoteAddress+' connected');
socket.setEncoding('utf8');
sockets.push(socket);
socket.on('data', function(data){
    console.log(data);
    var clients = sockets.length;
    for(var i=0; i<clients; i++){
        sockets[i].write(data);
    }
});
});
tcpServer.listen(1490, '192.168.3.XX');
