javascript - Ratchet socket from Android and IOS clients -

-

i've written socket php code using ratchet . here simple code, works when send , messages web - javascript:

    use ratchet\messagecomponentinterface;      class chat implements messagecomponentinterface{         protected $clients;          public function __construct(){             $this->clients = new splobjectstorage();         }          function onopen(\ratchet\connectioninterface $conn)         {             echo "did open\n";             $this->clients->attach($conn);         }           function onclose(\ratchet\connectioninterface $conn)         {             echo "did close\n";             $this->clients->detach($conn);         }           function onerror(\ratchet\connectioninterface $conn, \exception $e)         {             echo "the following error occured: ". $e->getmessage();         }           function onmessage(\ratchet\connectioninterface $from, $msg)         {             $msgobj = json_decode($msg);             echo $msgobj->msg;             foreach($this->clients $client){                 if($client !== $from){                     $client->send($msg);                 }             }         }  }

the problem when use java client - android app. use thread activity. has no exceptions, no errors. client.isconnected() true. no server code not called - onopen method, onmessage , others. how can fix this. same situation ios. client connects server nither of ratchet methods called. called javascript. java code :

new thread(new runnable() {             @override             public void run() {                 try {                     client = new socket("xx.xx.xx.xx", 2000);                      printwriter = new printwriter(client.getoutputstream());                     printwriter.write("android message");                     printwriter.flush();                     printwriter.close();                     client.close();                 } catch (exception e) {                     e.printstacktrace();                 }             }         }).start();

try use
android: https://github.com/tootallnate/java-websocket
ios: https://github.com/square/socketrocket
because ratchet websocket. , host name should starts ws://
