## What it is
An open-source instant messaging framework (SDK) for Android that provides a fully featured chat client with private, group, and public chat rooms. It supports pluggable backends including Firebase/Firestore and multiple XMPP servers, with authentication, push notifications, and media messaging built in.

## Use cases
- add chat messaging to an android app
- build a mobile messenger with firebase backend
- integrate xmpp chat client into android
- open source whatsapp-like messenger for android
- group chat and public chat rooms in android app
- chat sdk with push notifications and user profiles

## When to choose
- you need a quick, fully featured chat integration on Android
- you want backend flexibility between Firebase and XMPP servers
- you need full control and ownership of chat data
- you want an open-source alternative to proprietary chat SDKs

## When to avoid
- you need iOS or cross-platform chat support from one codebase
- you require a non-Firebase, non-XMPP backend without writing a custom adapter
- your project targets API levels below 23
- you need a backend-as-a-service with managed hosting and support
