## What it is
HermesEventBus is an Android library that extends greenrobot's EventBus to support event posting across processes via IPC, built on top of the Hermes IPC framework. It provides the same APIs as EventBus, making it a drop-in replacement for apps with multiple processes or plugin-based architectures.

## Use cases
- post events between processes in a multi-process Android app
- replace EventBus with a cross-process-capable event bus
- communicate between distinct Android apps via events
- send events between a host app and plugin processes
- simplify IPC without writing AIDL
- broadcast state changes across app processes

## When to choose
- your Android app runs multiple processes and needs EventBus-style communication
- you want a drop-in replacement for EventBus 3 with IPC support
- you develop Android plugins that must exchange events with the host app

## When to avoid
- your app is single-process and plain EventBus suffices
- you need a maintained library - the last release was in 2017
- you need high-throughput or structured messaging rather than simple event posting
- you use an EventBus version earlier than 3.0

## Facets
- artifact type: library
- maturity: maintenance
- function: message-queue, middleware
- domain: android-tools, mobile-development, developer-tools
- platform: jvm
- tags: eventbus, ipc, inter-process-communication, android, event-driven, cross-process
