## What it is
A collection of official sample apps demonstrating the Android NDK (native C/C++ development on Android), built with Android Studio and Gradle. Samples showcase individual NDK APIs such as JNI usage, camera, graphics, and best practices like RegisterNatives and version scripts.

## Use cases
- learn how to use the Android NDK with C++
- see examples of JNI native code in Android apps
- find a starting point for Vulkan or OpenGL native Android apps
- understand NDK best practices like RegisterNatives
- build native Android samples from the command line with Gradle

## When to choose
- you want official, maintained examples of Android NDK APIs
- you are learning native Android development with C/C++
- you need reference code for JNI, camera, or graphics APIs on Android

## When to avoid
- you need a production-quality app template (samples intentionally sacrifice robustness)
- you are building a pure Java/Kotlin app with no native code
- you want a general Android app architecture reference (use Now in Android instead)

## Facets
- artifact type: learning-resource
- maturity: active
- function: developer-tools, graphics, game-engine
- domain: mobile-development, developer-tools, tutorials
- platform: cpp, cross-platform
- tags: android-ndk, jni, sample-apps, cmake, vulkan, opengl, android-studio, game-development, android
