## What it is
The Android Native Development Kit (NDK) lets Android developers embed native C/C++ code in their apps as JNI shared libraries. This repository hosts the NDK's issue tracking, roadmap, and build-system documentation, with source maintained in AOSP.

## Use cases
- compile C++ code for Android apps
- build JNI shared libraries
- use Vulkan or high-performance audio APIs natively on Android
- debug native crashes and tombstones on Android
- build Android apps with CMake or ndk-build

## When to choose
- you need native C/C++ performance in an Android app
- you're porting an existing C/C++ library to Android
- you need access to low-level Android APIs like Vulkan or Neural Networks from native code

## When to avoid
- you're building a pure Java/Kotlin Android app with no native code
- you want cross-platform desktop development rather than Android

## Facets
- artifact type: library
- maturity: active
- function: compiler, build-tool, sdk, developer-tools
- domain: mobile-development, developer-tools, cross-platform
- platform: cpp, c, cli
- tags: jni, native-code, ndk, bionic, cmake, android-development, android
