## What it is
An archived Android sample app from Google demonstrating fingerprint authentication using the FingerprintDialog API. It has been migrated to the android/security-samples repository and is no longer maintained here.

## Use cases
- add fingerprint login to an android app
- learn android biometric authentication api
- sample code for fingerprint dialog on android
- implement biometric login in java android
- android security api best practices example

## When to choose
- you need a reference for legacy fingerprint dialog APIs on older Android versions
- you want to study Google's original Java sample for fingerprint auth

## When to avoid
- you need current, maintained biometric auth code - use android/security-samples BiometricLoginKotlin instead
- you target modern AndroidX BiometricPrompt APIs
- you need production-ready authentication code

## Facets
- artifact type: learning-resource
- maturity: abandoned
- function: auth, security, mobile-framework
- domain: android-tools, security, mobile-development, tutorials
- platform: jvm
- tags: fingerprint-authentication, biometric-authentication, sample-code, android-sample, deprecated, google-archive, android
