Google Chrome Extension Using With UDP -

i want develope basic extension. extension should communicate on udp. extension messaging. want create client. because create server in java. client can sent message server , server can message client.

i @ chrome developer page. these documents not date. create basic client this:

// values var address     = null; var connect     = null; var disconnect  = null;  // udp-object var echoclient  = null;  // -------------------------------------------------------------------------------------------------------------------  window.addeventlistener("load", function() {    // input: address.val   address = document.getelementbyid("address");    // button: connect.val   connect = document.getelementbyid("connect");    // button: disconnect.val   disconnect = document.getelementbyid("disconnect");    // button: connect.func   connect.onclick = function(ev) {     if(address.value != ""){       echoclient = newechoclient(address.value);     }   };    // button: disconnect.func   disconnect.onclick = function(ev) {     echoclient.disconnect();   }    // send data   setinterval(function(){      echoclient.sender();   }, 1000);  });  // -------------------------------------------------------------------------------------------------------------------  var newechoclient = function(address) {   var ec            = new chromenetworking.clients.echoclient();   ec.sender         = attachsend(ec);   var hostnameport  = address.split(":");   var hostname      = hostnameport[0];   var port          = (hostnameport[1] || 7) | 0;   ec.connect(     hostname, port,     function() {       console.log("connected");     }   );   return ec; };  var attachsend = function(client) {   var = 1;   return function(e) {     var data = i;     i++;     client.echo(data, function() {         console.debug(data.data); // problem here     });   }; }; 

but code not working. in chrome took error:

error in event handler sockets.udp.onreceive: rangeerror: byte length of uint32array should multiple of 4     @ chrome-extension://boeaihphlidceiemkegklmbmefjgogfk/networking.js:84:25     @ chrome-extension://boeaihphlidceiemkegklmbmefjgogfk/networking.js:31:34 

where wrong? problem?

afaik, chrome extension cannot use upd communication. stated in post, can either use both app , extension communicate, or use extension , native host.

i think chrome apps have access socket api , not chrome extension stated in post.

you can check this:

• write chrome extension support udp in browser?
• chrome.socket not usable extensions

the references talks chrome extension can't use chrome.socket.

hope helps.
