## What it is
FreeReflection is an Android library that removes the reflection restrictions introduced in Android P (and later), letting apps use hidden/non-SDK APIs as before. It works by hooking the runtime via a single Reflection.unseal() call in Application.attachBaseContext.

## Use cases
- bypass android p hidden api reflection restrictions
- access non-sdk android apis via reflection
- call hidden android framework methods on android 9 10 11
- unseal reflection restrictions in android app
- android library for unrestricted reflection

## When to choose
- you need to call hidden Android APIs on Android 9+ for compatibility or tooling
- you maintain legacy code relying on unrestricted reflection

## When to avoid
- you target only Android 8 or below
- you need Play-Store-safe code, since non-SDK API use may violate policies
- you need a maintained solution for the newest Android versions

## Facets
- artifact type: library
- maturity: maintenance
- function: security, developer-tools
- domain: android-tools, developer-tools, operating-systems
- platform: cpp, jvm
- tags: android-p, reflection-bypass, hooking, hidden-api, android
