The 4.4 KitKat release includes the results of “Project Svelte”: a set of tweaks to the operating system to make it run more easily on devices with around 512 MiB RAM. This is especially important for people working with Android Wearables and “Embedded Android”, that is, implementing Android on devices at the lower end of the Android ecosystem.
A large part of the problem is knowing how much RAM is really being used. Android offers a variety of tools for the purpose: procrank, procmem, meminfo and procstats, which I cover in the first part of the talk. In the second part I take a real-world example and show the practical steps you can take to optimize memory use including tuning the size of the Dalvik heap, enabling KSM (Kernel samepage merging) and swap to zRAM.
