Google has to Android 4.4, the experimental ART-compiler added. This runtime compiler would perform better than the current Dalvik compiler. The ART compiler is probably a further development of the DroidBooster software of the acquired FlexyCore.
That the ART runtime compiler is still an experimental character, is evident from the fact that this compiler manually must be activated in the Developer Options menu in Android 4.4 kit kat, reports XDA Developers. If a developer chooses for the ART compiler instead of the regular Dalvik compiler, then this will going to make use of so-called OAT-system files instead of Dalviks ODEX files. Furthermore, it contains the Android 4.4 software the dex2oat tool, which allows ODEX files to OAT format can be converted.
With the ART compiler seems Google already has a significant share of the Android-accelerator DroidBooster in kit kat. Google got DroidBooster in the hands after the recent takeover of the French company FlexyCore. DroidBooster would various optimizations contain compared to the Dalvik runtime compiler, among other things, by better native code to deliver and the underlying hardware is better exploited.
Android 4.4 kit kat contains several optimizations to the operating system to make it suitable for devices with 512MB of ram. The ART compiller seems now also to be part of Googles optimizing under codenamed Project Svelte, but it is unclear whether this new run-time compiler is already in the successor to kit kat Dalvik will be replaced.
