@Vegastroy .... ART is the new Android Runtime which was first introduced with the release of the KitKat O/S, it replaces Dalvik Runtime. The main purpose of ART is to improve performance and smoothness of the core Android platform and battery life. You can enable/disable it by going to :::: Settings>Developer Options>Select Runtime ::::
There have been some posts in motor g forum that complain that using "Art" causes several games to F/C or not run at all. The full benefit of having "Art Runtime" will probably not be seen until a future release of Android O/S which has been optimized for Art and then there will be Apps which are also optimized for Art, so things will get better.
For now , whilst there is still a choice in Settings to use either Art or Dalvik, there is nothing to stop you swapping about

Those who are using CM11 or other custom rom with low internal memory can now use ART runtime!
Just add this line to build.prop- dalvik.vm.dexopt-data-only=1
Enable ART runtime from Developer option!
Reboot your device. :laugh:
Please make sure that you have 150 mb space in data partition.
Then dalvik-cache/art-cache will be saved in /data partition instead of /cache partition.
Please hit thanks button if it works for you!
In my old sgs I can use it via dev options and just choosing ART, but imho it makes the phone a bit laggy and some apps fc... It needs a lot of improvement thats for sure

Excited to start using ART, but so far I'll be sticking with Dalvik since WhatsApp does not work with ART yet. :crying:
I always wondered. How much better is ART compared to using Dalvik?
Sorry, but there is already an ART discussion thread in General: http://forum.xda-developers.com/showthread.php?t=2531342
Thread closed.
What is ART?
ART stands for Android runtime which is a new runtime like Dalvik which is introduced experimentally in the 4.4 release. This is a preview of work in progress in KitKat that can be turned on in Settings > developer option.n 4.4 both runtimes are now available, Dalvik runtime (libdvm.so) and the ART (libart.so).The user can choose it from developer options.

Difference between Dalvik and ART
Dalvik
Dalvik runtime uses JIT(Just-In-Time) compilation to interpret Bytecode
Now lets understand the technical info and terms in the above sentence.

Compiler
A compiler is a program or set of programs that transforms source code written in a programming language (the source language) into another computer language
Click to expand...
Click to collapse
Bytecode
Bytecode also known as p-code (portable code), is a form of instruction set designed for efficient execution by a software interpreter
Click to expand...

Interpreter
Interpreter is a program which translates the source code into computer/machine language

JIT compliation
JIT compliation interprets the bytecode into machine language at it's runtime (at the time when the apps are executed).
Click to expand...

Now summing up all these Dalvik runtime does everything when the apps are executed. Now this is where we must discuss odexed and deodexed ROM. usually all stock ROMs released by OEMs are only odexed only due to this reason. odex means a part of the app is already compiled and it is written into dalvik VM(VM=Virtual Machine). and it runs at boot so while execution of apps JIT has to compile only the remaining part of the code when the apps is executed, this is why odexed ROM is faster than deodexed ROM.
But the disadvantage of odexed ROM is it cannot be edited/themed easily as a part of code is seperated in a separate file, and deodexing means the odex part of the file is put back into the apk/jar itself which makes editing/theming easy since the full code is packed inside a single file but it decreases speed because JIT has to compile full code when the app is executed
ART
ART uses AOT compilation to interpret bytecode.
I hope you can refer to dalvik paragraph to know about these technical terms.

what is AOT compilation
AOT is a method of compilation which compiles the code into machine language when the app is installed itself, means no compilation is done at the time of execution of app. This makes the apps launch speed amazingly fast.

Advantages of ART over Dalvik
The apps launch speed is amazingly fast in case of ART since nothing is compiled at execution.
Boot speed is faster than dalvik since nothing is execued from dalvik partition as in case of odexed ROM in dalvik
Increases battery backup by reducing CPU work due to absence of compilation work on apps execution.
And finally it is a great reward to developers because most of developers are worried that odexed ROMs are faster than deodexed ROMs but they will deodex their ROMs since they heavily theme it. In case of ART whether the ROM is odexed or deodexed it doesn't matter, it compiles the full code into machine language on installation of apps. so even deodexed ROMs are as fast as odexed in ART

Some disadvantages of ART
Since ART precompiles apps on installation, it takes 10-20% more space upon installation than dalvik. But this can be simply solved by using apps like apps2sd/link2sd/gl2sd when your apps storage partition is full
One more is since it is only experimental feature now some apps are incompatible in ART which will be made compatible soon on their updates.

Here is the list of apps which are compatible and incompatible in ART.

Finally ART is one of the best feature that google brought up in android 4.4 (kitkat)
I was wondering what was the difference between Dalvik and ART terms, but you made things pretty clear in this post. Thanks a lot
Thank you for this. Makes it a little easier to understand.
Explained me a lot, thanks!
Interesting information. Thank u very much for spend part of your time to write this
Thanks for that explanation, has made the whole thing clearer to me now
Thanks bRO. Very nice

Very nice explaination
Well organized, nice explaination, Thanks!!
What u suggest ? Why ? Currently on dalvik stock ROM & kernel

Hi,
Who is using ART instead of Dalvik VM?.
Switching runtime between Dalvik and ART.
Dedicated Runtime Thread (ART vs Dalvik).
Dalvik for now...
Art is still experimental feature
yeah dalvik for now imo
ART is good if not better and loads of apps do support it but its not stable
i use this website to see which apps are working:
http://www.androidruntime.com/list
Which of the above ones is better?
2nd question: I can't see experience kernel in trickster MOD.. I need double tap to wake screen .. How can I do it?
Please help

xposed is not compatible with ART.
With xperience kernel v.18, you need to install "Wake Gestures" module in Xposed. Then you can activate d2tw from the module.
Hope it helps.

I asked if dalvik with xposed was better than art ( excluding xposed as it isn't compatible! I know that :3 ) ... And that kernel isn't showing up on trickster mod...

Oh sorry if I misunderstood your question
I prefer dalvik with xposed. Because ART for now as they say is "experimental". From what I read, it's like a hit or miss thing. Some apps load faster with ART, some load slower than dalvik. And If you are using xposed modules, you're stock with dalvik anyway.
With the Xperience kernel, I have no idea. Because I am using fauxclock. And never encounter that issue with tricksterMod last time I used it. You can maybe try to do uninstall/install, clear cache and dalvik, reflash kernel. I'm no expert, so hopefully someone can help you futher.

Did you purchase fauxclock ?
Sent from my Moto G using XDA Free mobile app
Yes. I guess it's a good purchase if you want additional options. Specially if you use faux kernels. But the free trickersmod has sufficient options. [emoji4]

Hi all,
Switch to ART from Dalvik in runtime.. In developer options. Your device will ask for reboot and gets lollipop smoothness. I did it.. Phone performance increased.
My device: Indian Dual sim variant Moto G XT1033
Rom: Stock rom
Thanks,
Raviteja.
I'm Sorry. I don't know where to share my review in Xda, So I posted here.

But in some roms, you can get bootlop after changing. And in other roms, you will switch to art, reboot but there still will be dalvik
And, unfortunatelly, apps have bigger size with art ;/

Thanks for letting me know. I'm using Indian dual sim variant with stock rom and I switched with no issues.
Also some apps won't run on ART

Right Xposed, for example. It's not compatible with art

You write Lollipop: Is a typo or not? Since on Lollipop art is default runtime and dalvik is past away
