## What it is
A lightweight event bus library for Android that decouples communication between Activities, Fragments, Threads, and Services using an observer pattern with @Subscriber annotations and event tags. It supports thread modes and sticky events.

## Use cases
- send events between android activities and fragments
- decouple components in an android app
- communicate between a service and ui thread
- replace callbacks with event-based messaging
- post background events to the ui thread

## When to choose
- you want a small, simple event bus with tag-based routing on Android
- you need sticky events and thread-mode control without heavy dependencies

## When to avoid
- starting a new project where maintained alternatives like GreenRobot EventBus or RxJava/Kotlin Flow are preferred
- the project is explicitly no longer maintained and you need long-term support

## Facets
- artifact type: library
- maturity: maintenance
- function: middleware, concurrency
- domain: mobile-development, android-tools, developer-tools
- platform: jvm
- tags: eventbus, observer-pattern, pub-sub, annotation-processing, sticky-events, android, mobile
