didi/booster

Booster is an Android build tooling framework that enhances the Android Gradle Plugin by injecting bytecode transformers and runtime instrumentation to fix bugs, optimize performance, and analyze build artifacts. It provides a modular architecture for static analysis, dynamic class transformation, and build-time resource validation, while maintaining compatibility with modern AGP versions.

The project underwent a significant refactoring to support Android Gradle Plugin 8.x, replacing legacy APIs and removing compatibility layers for older AGP versions. This period also saw the introduction of numerous new instrumentation transformers for features like thread optimization, logcat interception, and resource validation, alongside the addition of several Gradle tasks for artifact and permission auditing.

The project focused on standardizing Android Gradle Plugin integration through a unified AGP interface, enabling support for multiple AGP versions (8.3, 8.10, 8.12). Concurrently, significant effort was invested in static analysis capabilities, introducing a modular Class Hierarchy Analysis (CHA) system with ASM-based parsing and call graph generation. The period also saw the addition of command-line tool execution frameworks, resource path resolution utilities, and comprehensive unit testing for these new components.
