The Android Runtime (ART) which Google introduced for testing purposes with its release of KitKat last year has now fully replaced the Dalvik virtual machine in the Android Open Source Project (AOSP) code.

This means you should expect the next version of Android (which could get official as soon as next week) to come with ART and only ART – Dalvik is essentially dead from this point on.

The change has been spotted in two commits made recently to the AOSP code. One of those removes Dalvik from master branch, while the other switches the default runtime compiler to ART.

So what’s the big deal, you ask? Well, in short: Dalvik uses a Just-In-Time compiler, while ART has an Ahead-Of-Time compiler. That means ART pre-compiles bytecode when an app is installed, while Dalvik does the same thing only when an app is started.

The use of ART should thus result in faster app start times, as well as better performance overall – though whether these improvements will be noticeable to end-users remains to be seen. For what it’s worth, Google says it can cut app start-up times in half with ART, and who wouldn’t want that?

Possible downsides to ART include apps taking up 10-20% more space in your device’s storage, and longer app installation times.

It was in beta and Google said to use it sparingly, as they continue working on it. Now, it will be the only option available. Currently, you can choose Dalvik or ART on your phone, however, not all phones have it.
 
Sigh. Unless dev's are already getting ready for this, goodbye xposed. :(
 
Giving ART a try on my S2, some people are reporting better battery life and performance. Worth a shot.
 
Tried ART on CM11, with ART compatible gapps, but I didn't notice much of an improvement over Dalvik. But then again CM11 dont run so well on the S4 (i9500).
Just wish the big phone manufacturers (HTC Samsung etc) would use ART, currently they still using Dalvik even though Google has included ART since introducing KitKat. If ART gets their backing then I'm sure the we'll have more apps being compatible.
 
Been running ART here for a few months already and except for my Whatsapp just displaying a white screen every 20 or so times I open it, everything appears fine. If I go to my home screen and back to Whatsapp it shows just fine. This is still the experimental one though running off a Moto G.

It did help my battery life too and apps opened noticeably faster

It helps to have ART supported by your manufacturer, Motorola/Google. Currently ART is only support on CM11 or CM11 based ROMs on my device. Sadly they dont perform well so back to TW based ROMs for me.

I had CM9 on my old Desire S and loved it, but sadly it caused me endless hassles with my Wifi so I ended up selling it. It was cool to mess around on though :)

So no chance of me rooting and fiddling with my Moto G (yet...) :D
 
Been running my S2 with ART since last night. Don't see any improvement with battery, it may actually be a little worse. Apps however do open noticeable quicker.
 
Bit of a necro, but useful info for those stuck on KitKat ;-)

This should work on any Kitkat installation, but your mileage might differ to what I experienced
Google your hardware and Dalvik to ART switch

I have a LG G Pad 8.3 that is more than 2 years old and stuck on KitKat
Hardware is still very good and can get Lollipop if I root and jump through hoops, I don't want to attempt that

Saw an article about the difference in performance when switching from Dalvik to ART runtime - decided to try

You have to enable Developer tab in settings by tapping the Build Version a couple of times - you will be informed when it is activated

Under Developer Options there is Select Runtime - here I switched from Dalvik to ART
Tablet rebooted and compiled existing info in about 20 minutes

My experiences after the switch
Tablet takes about 20 sec longer than before to start up
Every installed app works fine, but had to re-install a couple of widgets
The WOW factor
The tablet is now super responsive - feels like screen movement is glued to your finger tip - maybe placebo effect, but feels faster ;-)
Battery power improved visibly - I would say 30% to 40% based on what I got previously
Runs cooler than before
No more heat issues during charging when using the tablet at the same time

So, very happy with the change and wished I have done it sooner

Hope this info help ;-)

EDIT:
I am not going back to Dalvik, but you can switch back if you are not happy with ART

I'm replying to a necro'd threat but wtf.

I have a S3 Mini and I'm looking for something lightweight, never ever done anything like this before on a phone.

Some advice would be appreciated.

Why not grab the Marshmallow version with split screen multitasking that you can enable under developer options?

Install TWRP (download here)
Boot into recovery and flash the ROM. http://forum.xda-developers.com/devdb/project/dl/?id=18267
For Root flash SuperSU (download here)

Just back before you try this but the rom already include the gapps so it should be too simple to flash this.
