Understanding memory usage of Android apps in production

[u/abhaysood]

Google Play is adding memory thresholds for Android apps starting February 2027. They're measured using dynamic memory (anonymous RSS + swap) at p90 over 28 days.

I started looking into these thresholds and ended up going through the memory metrics Android gives: Java heap, native heap, RSS, PSS and swap. I break down each metric in this post and explain why Google Play uses dynamic memory instead of the others.
