## What it is
RocooFix is an Android hotfix framework that lets developers patch bugs in released apps without republishing, supporting both static (restart-required) and dynamic (immediate) fixes on Dalvik and ART VMs. It ships as a Gradle plugin plus runtime library that automates hash.txt and mapping.txt generation and supports ProGuard, Multidex, and beta native (so) library patching.

## Use cases
- fix bugs in a released android app without shipping a new apk
- apply runtime dex patches to an android application
- patch android app classes on dalvik and art devices
- generate hotfix patches automatically from gradle builds
- load a patch dex from assets or a local directory
- hot patch native so libraries in an android app

## When to choose
- you maintain a legacy Android app on old Gradle/AGP versions (1.3–2.1) and need a simple hotfix mechanism
- you want automated patch generation without manually managing hash.txt and mapping.txt files
- you need both static and dynamic patch modes on Dalvik and ART

## When to avoid
- you are starting a new project - the author recommends the successor AnoleFix or actively maintained frameworks like Tinker or Robust
- you need modern Android Gradle Plugin support, Windows build support, or ongoing bug fixes
- you need guaranteed compatibility with recent Android versions
