- inputs: {"age_days": 3934, "days_push": 1832, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
RxBus is an event bus library for Android/JVM built on RxJava, inspired by Otto and EventBus. It supports @Produce/@Subscribe annotations, event tags, and configurable threading (main, IO, computation, executor, handler threads).

## Use cases
- publish and subscribe to events across Android components
- replace Otto or greenrobot EventBus with an RxJava-based bus
- route events to specific threads like IO or main thread
- tag events to distinguish different message types
- decouple communication between activities, fragments, and services

## When to avoid
- you prefer a maintained, actively developed event bus (last release 2021)
- your project does not use RxJava and you want a lighter alternative like EventBus
- you need cross-process or cross-app event communication

## Facets
- artifact type: library
- maturity: maintenance
- function: message-queue, concurrency
- domain: android-tools, mobile-development, developer-tools
- platform: jvm
- tags: event-bus, rxjava, rxjava2, pub-sub, annotations, android
