local vs internet ws server

[dmtrlbdv1]

I am trying to open connection to the server and now I have an issue with it. If it local started crossbar.io server - I am able to connect to it, but I am can't connect to any internet server ( for example wss://demo.crossbar.io/ws ). In this case only cycled disconnect-connection states. What I am doing incorrect ?

try { // Create a builder and configure the client WampClientBuilder builder = new WampClientBuilder();

// builder.withUri("ws://192.168.1.39:8282/ws") builder.withUri("wss://demo.crossbar.io/ws") .withRealm("realm1") .withInfiniteReconnects() .withReconnectInterval(5, TimeUnit.SECONDS); // Create a client through the builder. This will not immediatly start // a connection attempt client = builder.build();

        client.statusChanged().subscribe(new Action1<WampClient.Status>() {
            private Subscription procSubscription;

            public void call(WampClient.Status t1) {
                Log.d("info", "Session status changed to " + t1);

                if (t1 == WampClient.Status.Connected) {
                    Log.d("info", "Connected");
                }
            }
        });

        client.open();

    } catch (WampError e) {
        // Catch exceptions that will be thrown in case of invalid configuration
        e.printStackTrace();
        return;
    }

I am sorry - I forget to add... I try to connect from the android (device and emulator), if it important

Your code is correct. Does your android app have the internet permission?

[dmtrlbdv1]

Yes, internet permission is set ( as I said my localhost is available form my app ). May be I do not set some dependencies in gradle ? ( maven repository have set in another gradle file ) Or may be I need make some steps to connect to wss server ? I tried withSslContext(SslContext.newClientContext(InsecureTrustManagerFactory.INSTANCE)) - but nothing changed.

apply plugin: 'com.android.application'

android {

Sorry, can't help you regarding Android configuration as I have no experience with that. In #21 there was a discussion about the correct settings for Proguard, maybe you have a problem with that. @jrogers also build an example for android, maybe this helps: https://github.com/jrogers/AndroidWampExample

If you want to debug why the connection fails you could put breakpoints in the associated Netty Channel Handlers for the connection (e.g. in WampClientWebsocketHandler, WebSocketClientProtocolHandler, WebSocketClientProtocolHandshakeHandler, WebSocketClientHandshaker08). Sorry - currently don't have time to investigate that deeper myself.

Thank you. I found nexus 7 (5.0) and tried to start my app on it - all working! I do not understand why samsung galaxy s not allow me to connect. I hope it is just certificates issue or something and my server will be working without problems.
