Unlike JIT, which must compile every app whenever its loaded, ART works on a concept called ahead-of-time (AOT) compilation.

Yes, virtual machines, but well get to those in just a moment.

What makes all this relevant now is the decision by Google to include a new runtime in Android 4.4 KitKat one that promises to make your device faster, your battery last longer, and give you thicker, more manageable hair.

Theyre the computer under your desk, the notebook on your lap, the server in the closet down the hall.

When you think of a computer, this is what youre probably picturing.

Dalvik Virtual Hine Android Mac And Youre

Confused yet Say your desktop computer is a Mac and youre running some flavor of OS X.

Youve got a couple programs that you want to run that dont work in your OS.

You might want to load up a couple virtual machines and install Windows into one and Linux into another.

These virtual machines emulate all the hardware that is needed for you to install and run an operating system.

You can literally run a complete Windows environment in a window on your Mac, and the same goes for Linux or almost any other operating system.

Apps that run in the VM are separate from those running in the host environment.

Viruses, malware, and even crashed apps are all kept apart from your main OS, insulating you from the implications of such occurrences.

Another advantage of VMs is the ability to run programs written for one architecture on a box that runs something different.

Back then developers would write their apps, then compile them for several platforms: ARM version 4, Intel XScale, MIPS, or SH3 CPUs.

Each processor had its own advantages and disadvantages, but they all required separately compiled versions of every app that you hoped to run on any one of them.

When Pocket PC 2002 was announced, Microsoft standardized on ARM.

Developers write code which you, the end user, install from the Play Store or some other source.

That means its slower than compiled code would be, but your device gets the insulation advantages that VMs provide, and developers dont have to worry about re-compiling their code to run on some other CPU like a new tablet, PC, TV, watch, or even a rice cooker.

Its a great concept, but one that has quite a bit of overhead when you first launch apps.

When you do, Android pulls all the uncompiled data together, compiles it, and loads the app into memory (RAM).

As long as the app is there, after the initial load time, its pretty snappy.

If you use a task killer, manually kill the app, or navigate away and load up other apps, the first app is unloaded, freeing up the RAM it had been using.

When you go back to it, its got to go through the whole process all over again.

Though its not a very creative name, it is pretty creative in what it does.
