PubNub no longer supports these Android and iOS software libraries, but you are welcome to contribute.

PubNub Chat Components are ready-made building blocks you can use to either create web and mobile chat apps from scratch or add chat features to your existing applications.

Run both apps and start a real-time conversation between iOS (Ian) and Android (Anne) chat users.
