A modular and portable open source XMPP client library written in Java for Android and Java SE VMs.
Smack is an open-source XMPP client library written in Java for Java SE compatible JVMs and Android. It provides a modular and easy-to-use API for integrating XMPP functionality into applications, enabling real-time data exchange between human and machine endpoints. The library can be embedded to create anything from full instant messaging clients to simple notification systems and IoT integrations.
Java and Android developers who need to add XMPP-based real-time communication to their applications, including those working on instant messaging clients, notification systems, M2M applications, and IoT projects.
Developers choose Smack for its pure Java implementation that works consistently across Android and Java SE, its highly modular architecture that minimizes dependencies, and its comprehensive XMPP protocol support that simplifies complex real-time communication implementations.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Highly modular design allows developers to include only required components, minimizing dependencies and bloat, as emphasized in the overview.
Runs on both Java SE and Android with a uniform API, enabling code reuse and simplifying development for multi-platform projects.
Simple to embed into applications for creating anything from full XMPP clients to simple notifications, highlighted in the getting started guide.
Supports various XMPP patterns like fire-and-forget and publish-subscribe, making it suitable for M2M and IoT applications as described in the features.
New users must create a forum account and post issues there instead of using a direct bug tracker, adding friction to support processes as outlined in the bug reporting section.
Multiple licenses across subprojects require careful handling of NOTICE files, which can be burdensome for compliance, as noted in the license section.
Support responses can take hours via XMPP chat or forums, which may not suit time-sensitive development needs, as mentioned in the contact section.
