The default threshold to trigger background reclaim is fairly low, around 2MB on a 2GB device and 636KB on a 512MB device.This documentation is intended to help OEMs optimize and configure Android 4.4 for low-memory devices.Several of these optimizations are generic enough that they can be applied to previous releases as well.

Maka untu yang punya HH Android dengan RAM yang kecil, sering Hang dan Lag, coba cara. Mavis Beacon Teaches Typing 17 Deluxe Setup Serial Key here. Dont allow large services to put themselves back into A Services (so they cant cause the launcher to be killed). ![]() Tuned memory use of low-RAM devices: tighter out-of-memory (OOM) adjustment levels, smaller graphics caches, etc. Reduced system memory Trimmed systemserver and SystemUI processes (saved several MBs). Validated JIT-off option (saves up to 1.5MB per process). Reduced per-process font cache overhead. Introduced ArrayMapArraySet and used extensively in framework as a lighter-footprint replacement for HashMapHashSet. Procstats Added a new Developer Option to show memory state and application memory usage ranked by how often they run and amount of memory consumed. API Added a new ActivityManager.isLowRamDevice() to allow applications to detect when running on low memory devices and choose to disable large-RAM features. Memory tracking New memtrack HAL to track graphics memory allocations, additional information in dumpsys meminfo, clarified summaries in meminfo (for example reported free RAM includes RAM of cached processes, so that OEMs dont try to optimize the wrong thing). Build-time configuration Enable Low Ram Device flag We are introducing a new API called ActivityManager.isLowRamDevice() for applications to determine if they should turn off specific memory-intensive features that work poorly on low-memory devices. It can be enabled by the following system property in the device makefile. PRODUCTPROPERTYOVERRIDES ro.config.lowramtrue Launcher Configs Ensure the default wallpaper setup on launcher is not using live-wallpaper. Cara Memasang Script Ram Optimizer Install Any LiveLow-memory devices should not pre-install any live wallpapers. Kernel configuration Tuning kernelActivityManager to reduce direct reclaim Direct reclaim happens when a process or the kernel tries to allocate a page of memory (either directly or due to faulting in a new page) and the kernel has used all available free memory. This requires the kernel to block the allocation while it frees up a page. ![]() This can result in extra IO in any thread, including a UI thread. To avoid direct reclaim, the kernel has watermarks that trigger kswapd or background reclaim. This is a thread that tries to free up pages so the next time a real thread allocates it can succeed quickly.
