Android Performance for Dummies (and Experts)
summary
Covers actionable checks and fixes: use Android Vitals to see ANR, crash, wake‑lock and startup percentiles; reduce APKs with minifyEnabled + shrinkResources + proguard and use Google Play app bundles; run APK Size Analyzer (example PNG true color 196 KB becomes 42 KB as an 8‑bit indexed image); profile CPU with Android Studio (sampling vs traced methods, top‑down / bottom‑up / flame charts) and GPU with the 16 ms target per frame and GPU overdraw colors; benchmark with Jetpack Benchmark (needs real devices; CI is possible but tricky).
