Smack is an open source, highly modular, easy to use, XMPP client library written in Java for Java SE compatible JVMs and Android.

A pure Java library, it can be embedded into your applications to create anything from a full XMPP instant messaging client to simple XMPP integrations such as sending notification messages and presence-enabling devices. Smack and XMPP allows you to easily exchange data, in various ways e.g. fire-and-forget, publish-subscribe, between human and non-human endpoints (M2M, IoT, …).

More information are provided by the Overview.

Getting started

Start with having a look at the Docmentation and the Javadoc.

Instructions how to use Smack in your Java or Android project are provided in the Smack 4.2 Readme and Upgrade Guide.
