Keeping minimum requirement of RAM for 512 MB, was challenge for Google Android KitKat for running smoothly on lower memory devices. That lead to many memory optimization technique and process. Google Android KitKat 4.4 help you to create innovative, responsive and memory efficient application. Dalvik JIT code cache tuning, kernel samepage merging (KSM), swap to zRAM, and other optimizations help manage memory. New configuration options let OEMs tune out-of-memory levels for processes, set graphics cache sizes, control memory reclaim, and more.
“A new API, ActivityManager.isLowRamDevice(), lets you tune your app's behavior to match the device's memory configuration” Google Android stated in documentation of KitKat
