## What it is
AndFix is an Android library that provides online hot-fix capability, allowing developers to patch bugs in a shipped app by replacing method bodies at runtime without redistributing the app. It supports Android 2.3-7.0 on Dalvik and ART runtimes, ARM and x86 architectures, and includes an apkpatch tool for generating .apatch files.

## Use cases
- fix bugs in a released android app without publishing an update
- apply runtime method-level patches to android apps
- hot-fix critical crashes in production android apps
- generate patch files comparing old and new android apks
- distribute app patches from my own server

## When to choose
- you must hot-fix a legacy Android app running Android 2.3-7.0 without a store update
- you need method-level native patching on Dalvik or ART

## When to avoid
- you target Android 8.0 or newer, which AndFix does not support
- you want an actively maintained hot-fix solution
- your project uses modern Android build tooling and Java versions
