## What it is
ReLinker is a Java library for Android that provides a robust replacement for System.loadLibrary, fixing intermittent UnsatisfiedLinkError crashes when loading native (JNI) libraries. It is needed mainly for apps with a minimum SDK below API 23.

## Use cases
- fix UnsatisfiedLinkError crashes when loading native libraries on Android
- reliably load .so native libraries on older Android versions
- replace System.loadLibrary with a more robust loader
- handle intermittent native library loading failures on Android
- support JNI libraries in apps with min SDK below 23

## When to choose
- your Android app bundles native libraries and supports min SDK below API 23
- you see intermittent 'findLibrary returned null' or UnsatisfiedLinkError stack traces in production
- you want a drop-in replacement for System.loadLibrary

## When to avoid
- your app's minimum SDK is API 23 (Marshmallow) or higher, where System.loadLibrary is safe
- native library loading fails consistently, which indicates a configuration issue rather than the intermittent bugs ReLinker fixes
- you are not developing for Android
