## Description

Tinker is an Android hotfix framework designed to update application code, resources, and native libraries at runtime without requiring a full reinstallation or store update. It provides a comprehensive engine for injecting runtime fixes and managing the software lifecycle of deployed mobile applications.

The framework distinguishes itself through a robust binary patching system that generates compact difference files between application versions, significantly reducing bandwidth usage during distribution. To ensure operational stability, it incorporates a crash-resilient safe mode that automatically disables faulty updates if repeated failures are detected during initialization.

The system includes integrated tools for verifying the authenticity and integrity of patch files using cryptographic checksums before execution. It supports the replacement of assets and shared object files, allowing developers to resolve functional or visual issues while maintaining the current user session state.
