How to optimize Android for low RAM hardware

Published on: 3rd May, 2022

This episode features a spirited nerding out over how we've used and developed for devices with minuscule amounts of RAM. From the days of Project Svelte on Android KitKat all the way up to Android Go Edition with Oreo, we go far and wide while trying to patch up any potholes that could crash apps or the operating system itself. Buckle in for a wild ride.

We're joined by Nolen Johnson, part of the team at DirectDefense, and Sean Hoyt, LineageOS developer.

  • 11:47 - What is Project Svelte and how did it help?
  • 16:56 - What tricks did device OEMs use to stretch active memory?
  • 21:56 - What does the Low RAM flag do in Project Svelte?
  • 25:46 - What's Android Go Edition?
  • 33:42 - Are there any other coping mechanisms outside of what Svelte and Go have offered?
  • 38:21 - Will RAM optimizations eventually kill the 32-bit application?
