## What it is
An official Google repository of Android sample apps demonstrating security best practices, including the Play Integrity API, biometric login, and DirectBoot device-protected storage. Written in Kotlin, it serves as reference code for integrating Android security APIs.

## Use cases
- learn how to integrate the Play Integrity API end to end
- add biometric authentication to an Android app
- store data in device-protected storage with DirectBoot
- find canonical examples of Android security API usage
- set up APK signing for developer verification
- follow best practices for Android app security

## When to choose
- you are building an Android app and need reference implementations of security APIs
- you want official, canonical sample code for biometrics or Play Integrity
- you are learning Android security best practices from maintained examples

## When to avoid
- you need a production-ready library rather than sample code
- you rely on the deprecated samples (BiometricLogin, DirectBoot) which are being deleted in March 2026
- you are not developing for Android

## Facets
- artifact type: learning-resource
- maturity: active
- function: security, auth, cryptography
- domain: security, android-tools, developer-tools, tutorials
- platform: jvm
- tags: android-security, sample-code, biometrics, play-integrity, keystore, google-official, android
