## What it is
A library and tooling project that provides access to Android hidden APIs (com.android.internal and @hide members) via a custom android.jar. It includes a hiddenjar CLI that builds a custom android.jar from a running emulator or device over adb, merging the full boot classpath.

## Use cases
- access android hidden apis in my app
- build a custom android.jar with internal resources
- compile against com.android.internal classes
- extract framework jars from an emulator over adb
- use hidden apis that moved to apex mainline modules
- replace android.jar in the sdk platforms directory

## When to choose
- you need to call @hide or com.android.internal APIs during development
- you want a jar generated for any API level from a live device or emulator
- you need hidden APIs from APEX/mainline modules beyond framework.jar

## When to avoid
- you only use public SDK APIs
- you need guaranteed API stability across Android versions
- you cannot run an emulator or connected device for jar generation

## Facets
- artifact type: library
- maturity: active
- function: sdk, developer-tools, cli
- domain: android-tools, developer-tools, mobile-development
- platform: cli, jvm, windows
- tags: hidden-api, android-jar, adb, dex-tools, android-sdk, android, macos, linux
