## Health v2 (maintenance only)
Score: 77/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 99, release rhythm 35, longevity 100
- inputs: {"age_days": 4206, "days_push": 8, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Official Android sample collection demonstrating performance libraries like Macrobenchmark, Microbenchmark, and JankStats. It shows best practices for measuring startup, jank, and runtime performance, including Baseline Profile generation.

## Use cases
- measure android app startup time
- detect janky frames in jetpack compose
- generate baseline profiles for android app
- benchmark android app code with microbenchmark
- run macrobenchmarks on firebase test lab
- learn android performance best practices

## When to choose
- you want official, maintained example code for Android performance libraries
- you need a starting point for Macrobenchmark or JankStats integration
- you want CI examples running benchmarks on Firebase Test Lab

## When to avoid
- you need a production-ready benchmarking framework rather than sample code
- your project is not Android/Kotlin
- you need performance monitoring for backend services

## Facets
- artifact type: learning-resource
- maturity: active
- function: benchmarking, testing
- domain: mobile-development, performance, tutorials
- platform: jvm
- tags: macrobenchmark, microbenchmark, jankstats, baseline-profiles, sample-code, jetpack-compose, android
