Autobahn- WAMPV2 support for Android

[ssaxe...@gmail.com]

Hi there,

I need to integrate Autobahn- WAMPV2 in my Android app but I found that it is still in development. When it is likely to be ready for integration in the app?

Hi!

We have started looking into this and I hope to something soon. I can't give an exact date, though you can track this issue https://github.com/crossbario/autobahn-java/issues/146 for updates.

Thanks!

Hi Omer, I noticed that you have merged https://github.com/crossbario/autobahn-java/issues/146 to master recently. Is it now ready for WAMP_V2 integration in Android?

I was trying to connect the client using the code example given there but the demonstrateSubscribe and demonstratePublish callback were never invoked. I am using following code to establish the connection-

Session session = new Session();
// Add all onJoin listeners
session.addOnJoinListener(this::demonstrateSubscribe);
session.addOnJoinListener(this::demonstratePublish);

// Now create a transport list to try and add transports to it.
// In our case, we currnetly only have Netty based WAMP-over-WebSocket.
List<ITransport> transports = new ArrayList<>();
transports.add(new NettyTransport("wss://xxxxxx/wss2/"));

// Now provide a list of authentication methods.
// We only support anonymous auth currently.
List<IAuthenticator> authenticators = new ArrayList<>();
authenticators.add(new AnonymousAuth());

// finally, provide everything to a Client instance and connect
Client client = new Client(transports);
client.add(session, "streamName", authenticators);
client.connect();

Please let me know if I am missing something.

Yes, android support did land, though we haven't yet done an official release.

Kindly take a look at this detailed example https://github.com/crossbario/autobahn-java/blob/master/demo-gallery/src/main/java/io/crossbar/autobahn/demogallery/ExampleClient.java

do note that on Android you should be using AndroidWebSocket as transport instead of NettyTransport.

Thanks for the quick response Omer. I will try your suggestions.

One more question, as the WAMP layer is using Java 8 features for WAMP actions and in Android java 8 is supported on API 24 (Nougat) and above. It is only around 10% of the current market share. So are guys planning to make it compatible with older Android versions?

Re: older Androids, we do plan to provide some kind of support using streamsupport library but thats going to be a while.

Omer I am unable to find the 'AndroidWebSocket' class in the jar file created using make and docker as explained by you here: https://groups.google.com/forum/#!topic/autobahnws/zWHqe-P93KQ. Please assist me.

You don't need to use the jar file directly. Just add below line to your build.gradle 

compile 'io.crossbar.autobahn:autobahn-android:17.10.4'
