How Android Approaches Leveling Guide for your Performance Journey
Original post Android Developers Blog: Leveling Guide for your Performance Journey
Article Summary
Google's Android team just dropped a performance framework that meets you where you are. Whether you're a solo dev or leading a performance team, there's a clear path forward.
Alice Yuan, Senior Developer Relations Engineer at Google, outlines a five-level performance optimization framework for Android developers. Each level builds on the last, from basic monitoring to custom production instrumentation.
Key Takeaways
- Level 1: Start free with Play Console tracking crash rates and ANRs automatically
- Level 2: App Performance Score (0-100) pinpoints high-leverage configuration wins like R8 minification
- Level 3-4: Macrobenchmark automates testing while Perfetto traces reveal system-wide bottlenecks
- Level 5: Android 15 APIs enable custom production monitoring for advanced teams
- New metric alert: Excessive partial wake locks now tracked (sessions over 2 hours)
Android performance optimization now has a clear progression path from zero-cost Play Console monitoring to custom production frameworks with Android 15 APIs.

What This Article Covers
Android developers have a hard time pinpointing performance bottlenecks when their apps run in different scenarios. Cold startup times, notification performance, and rendering during scrolling all matter, but there's no easy way to measure them without automated tools.
Alice Yuan's framework adds Macrobenchmark and UiAutomator at Level 3 to measure performance automatically. It wraps user interaction simulations inside benchmark blocks so developers can catch jank and frame rate issues.
Developers can now test their apps on lower-end devices to surface performance problems more easily. This gives them real data to guide optimization work instead of relying on manual testing alone.
