Trying to use third party lib (PubNub) to handle messaging

[green...@gmail.com]

It seems that CodenameOne doesn't support the third party lib, can anyone give advice for this?

This used to work fine. Make sure you included all the dependencies as pubnub included other dependencies. Also make sure you installed the library correctly.

Hi Shai,

I used below code to receive the message, but it didn't come. Do I need to execute this subscribe somewhere like original PubNub needs to execute after subscribe.

    public void subMessage() {
       
        Pubnub pubnub = new Pubnub(publishKey, subscribeKey);
       
        try {
           
            String channel = "testChannel";
            pubnub.subscribe(channel, new Callback() {
                @Override
                public void successCallback(String channel, Object message, String timetoken) {

                    System.out.println("Message is comming!!!!!!!!!!!!!!!!!!"+timetoken);
                }
            });

        }catch(PubnubException err) {
            Log.e(err);
            Dialog.show("Error", "There was a communication error: " + err, "OK", null);
        }
           
    }

Hi,

I think pubnub cut support for older libraries they implemented. I haven't paid much attention since websockets proved to be a good substitute and removed the need for solutions like that.

Where can I get the Websockets document and sample code? Then I can implement in my app as well, thanks!

There is also a WebSocket sample in the SampleRunner

https://github.com/codenameone/CodenameOne/tree/master/Samples

The sample (a chat app), should run out of the box. Just download the CN1 sources, open the Sample Runner (instructions at link above), and click "Launch" next to the WebSocketSample.

Hi Shai,

I changed to Websocket, and it works perfectly for me now.

Thanks!
