Make the Most of Android Vitals
summary
Shows how to use Google Play Console Android Vitals together with Android Studio profilers to find and fix startup, rendering, and ANR hotspots. Describes capturing ANR thread dumps, uploading ProGuard mappings, running long Release/pre-release automated UI tests, using code-level method tracing and Device File Explorer to retrieve traces, and moving heavy initializations (e.g., Kinesis Firehose, ThreeTenABP zone data) off the main thread with Dagger lazy plus background init to cut view-init latency to about three seconds; also uses narrow one-frame traces to diagnose jank.
