Redex
A bytecode optimizer for Android apps
Features
- Bytecode Optimizers - Provides the core bytecode optimization engine that shrinks and speeds up Android APKs.
- Android Bytecode Shrinkers - Removes unused code and resources from Android bytecode to produce a smaller application package.
- DEX Analyzers - Reads and transforms .dex files through a structured framework for custom optimization passes.
- Type Preservation for Reflection - Prevents deletion of classes or interfaces referenced through reflection or instanceof checks.
- APK Package Managers - Removing unused code and resources from compiled Android bytecode to produce a smaller application package.
- Android Performance Optimizations - Shrinks and speeds up Android APKs by applying bytecode optimization passes.
- DEX-to-IR Pipelines - Transforms Android bytecode through a sequence of passes operating on an intermediate representation.
- Pass-Based Optimizations - Runs independent optimization passes in a configurable sequence, each mutating the shared IR.
- APK Size Optimizers - Remove unused code and resources from Android bytecode to reduce the final APK file size.
- Bytecode Execution Optimizers - Reduces execution time and memory usage by optimizing bytecode instructions during app operation.
- Keep Rule Engines - Preserves classes and members matching ProGuard-style keep rules to prevent removal of reflection-accessed code.
- Obfuscation and Shrinking Rules - Protects specific classes and interfaces from removal during bytecode shrinking by accepting ProGuard configuration files.
- Android Utility Tools - Bytecode optimizer for Android applications.
