*remember to wipe cache and dalvik cache if you come from previous build

*** Why enable DEXPREOPT? ***
*ART uses ahead-of-time (AOT) compilation. This means that, at installation, dex code is compiled to native code in OAT files, which replace Dalvik’s dex files. This has several implications:
*Performance is improved over Dalvik.
*There is no runtime code cache. The OAT files are mapped to memory (and are thus page-able).
*Similar to preloaded classes in the zygote, ART attempts to pre-initialize a set of classes at compile time. This creates a ‘boot.art’ file that comprises an image of the compacted heap of pre-initialized classes and related objects. This file is mapped into memory upon zygote startup. While this consumes additional storage (typically 10MB), it speeds zygote startup and creates opportunities for the system to swap out some preloaded classes under memory pressure. This also contributes to improved low-RAM performance for ART, since in Dalvik much of this class information would have been stored in dirty pages in the linear alloc space.
*Dex file compilation uses a tool called dex2oat and takes more time than dexopt. The increase in time varies, but 2-3x increases in compile time are not unusual. For example, apps that typically take a second to install using dexopt might take 2-3 seconds.
*Because the ROM size is small.
*To save some space on data partition
