android client websocket délai d'attente

Merci pour la lecture!

De fond:
Je suis en train d'élaborer un client Android pour un serveur où la condition est une application qui nécessite un échange continu de messages d'avant en arrière avec un WebSocketsserver.

Mise en œuvre: Pour le client, j'utilise weberknecht de l' WebSocket de la bibliothèque du client pour Android alors que le serveur est Tornado.

Problème:
Pour le moment, j'invoque initWebSocketClient dans onCreate par la ponte d'une AsyncTask. Mais, je reçois un client exception délai.

Client Android:

private void initWebSocketClient() {
        Log.e(TAG, "initWebSocketClient");
        try {
            URI url = new URI("ws://192.168.207.84:8080/");
            WebSocket websocket = new WebSocketConnection(url);

            //Register Event Handlers
            websocket.setEventHandler(new WebSocketEventHandler() {
                    public void onOpen()
                    {
                            Log.e(TAG, "--open");
                    }

                    public void onMessage(WebSocketMessage message)
                    {
                            Log.e(TAG, "--received message: " + message.getText());
                    }

                    public void onClose()
                    {
                            Log.e(TAG, "--close"); 
                    }
            });

            //Establish WebSocket Connection
            websocket.connect();

            //Send UTF-8 Text
            websocket.send("hello world");

            //Close WebSocket Connection
            websocket.close();
        }
        catch (WebSocketException wse) {
                wse.printStackTrace();
        }
        catch (URISyntaxException use) {
                use.printStackTrace();
        }
    }

Tornade Serveur:

#!/usr/bin/env python

import tornado.ioloop
import tornado.web
import tornado.websocket

class EchoWebSocketHandler(tornado.websocket.WebSocketHandler):
    def open(self):
        print "WebSocket opened"

    def on_message(self, message):
        self.write_message(u"You said: " + message)

    def on_close(self):
        print "WebSocket closed"

application = tornado.web.Application([
    (r"/", EchoWebSocketHandler),
])

if __name__ == "__main__":
    application.listen(8080)
    tornado.ioloop.IOLoop.instance().start()

Client exception Délai:

Quelqu'un pourrait s'il vous plaît aidez-moi à sortir d'ici?

Mise à jour: l'Ajout d'AutoBahn (WebSocket de la bibliothèque du client pour Android) détails de mise en œuvre:

AutoBahn Client

private void connect2() {
mConnection = new WebSocketConnection();
final String wsuri = "ws://192.168.0.137:8888/";
String TAG = "ArticlesListActivity"; 
try {
mConnection.connect(wsuri, new WebSocketHandler() {
@Override
public void onOpen() {
Log.e(TAG, "Connected to: " + wsuri);
}
@Override
public void onTextMessage(String payload) {
Log.e(TAG, "Message recieved = " + payload);
}
@Override
public void onClose(int code, String reason) {
Log.e(TAG, "Connection Lost.");
}
});
} catch (WebSocketException e) {
Log.d(TAG, e.toString());
}      
}

Avec cette bibliothèque, je suis en mesure de se connecter au serveur, mais instantanément, la connexion est perdue. (Reportez-vous à la "AutoBahn Journal Client" ci-dessous. En revenant à weberknecht fonctionne très bien. Je ne suis PAS explicitement appel mConnection.disconnect() n'importe où. Donc je ne sais pas comment la connexion devient fin.
