How to optimize artwork resolution to save resources on Android device

Currently I'm optimizing my game for Android and I want to save disk space and RAM usage on users device. My reference resolution for art is 2732 x 2048 (the largest for mobile devices).
My thought is to build separate APK for most common 1920x1080 resolution so artwork will use nearly twice less space.

I know that there is no option to achieve this directly. Android store allows to manipulate only with obscure screen parameters (size and density), so that the same resolution can go to different buckets.

Any advice on how to approach this?
