What problem does it solve?
R8/ProGuard keep rules often grow overly broad and prevent effective shrinking, leading to larger APKs and weaker optimization while still risking broken runtime behavior.
Core Features & Use Cases
- Detects redundant and harmful keep rules: Flags library-wide keep patterns (e.g., AndroidX/Kotlin) that are typically unnecessary because dependencies ship their own consumer rules.
- Refines keep rules using an impact hierarchy: Evaluates remaining rules and identifies broader rules that can be narrowed to reduce code retention.
- Guides reflective retention precisely: Inspects code and adjacent usage patterns to suggest narrow keep rules aligned to reflection scenarios.
Quick Start
Run the r8-analyzer on your project to generate an R8 keep-rule analysis report and actionable removal/refinement recommendations.
