greenrobot/EventBus
This system is a high-performance, cross-platform event bus library that facilitates asynchronous communication between components. It provides a core Java implementation with optional Android-specific integrations, including main-thread scheduling and logging. The architecture supports compile-time subscriber indexing to optimize performance and includes utilities for background task execution and error handling.

How it got here
2012 · Gradle migration and project restructuring
The project underwent a significant modernization of its build infrastructure, migrating from a legacy Eclipse/ADT setup to a multi-module Gradle configuration. This period involved removing obsolete code and test suites while establishing a clean, standardized project structure with proper documentation and dependency management.

2014–2021 · Android decoupling and performance
This period focused on decoupling the EventBus core from Android dependencies, enabling the library to function in non-Android environments. The work introduced compile-time subscriber indexing to improve runtime performance and added utilities for background task execution. Additionally, the codebase was restructured to support separate Java and Android test suites, alongside new performance benchmarking tools.

About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit 0194926b3b — the exact code this score is about.
- Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
