New PubNub Instance on every Activity? about android-webrtc-api HOT 1 CLOSED

PubNub operates using a complex backend with caching of recently subscribed users and HTTP long polling. Messages are stored for a short amount of time so you will not miss anything if you transition between activities. Singleton isn't a bad idea for a messaging app where you should always be listening, but for AndroidRTC I was subscribing to different channels for different activities. Basically if I had a singleton, the procedure would be cancelling a HTTP request in unsubscribing from a channel and then reopening another for a different channel. I did the same thing allowing a slight overhead in recreating an object in exchange for channel manageability. I will make a singleton demo soon and let you know how it works.

Also since it is all polling, the "Logout" of pubnub is unsubscribing.

@Override 
protected void onStop() { 
     super.onStop(); 
     if(this.mPubNub!=null){ 
         this.mPubNub.unsubscribeAll(); 
     } 
 }
