I was watching the hands on video of Nexus 5 on GSMArena, and at the end I saw the reviewer mentioned and showed that there's something new under Developers settings, called Runtime ART or Dalvik. Like he said that enabling ART mode makes the app load faster and is battery efficient too. Now I have minimal knowledge about Java, so it's a rather simple question, could it be used on our S4?
It looks like ART runtime will replace dalvik at some stage so its a matter of when and not if. There won't be a problem with the s4 running it, it but apps will need to be optimised for it, hence why some are force closing when switching to ART.

i just switched to ART instead of Dalvik and its looking pretty slow for me right now. looooong boot and slow "Android is upgrading..."
will i see any difference?
Once its boots up; its fast. As Google mentioned > This is a preview of work in progress in KitKat that can be turned on in Settings > developer options.

Any particular settings required. pls assist if u know. further, does it make any difference on 2g RAM whether use dalvik or art.?
The fact that it take longer to boot (for the first boot only) conform with how ART work. Your questions can be answered by reading "What is ART" in this article: http://www.androidpolice.com/2013/1...-in-secret-for-over-2-years-debuts-in-kitkat/

ahhh yes.... rebooting with art and gonna give it a go for a day.
okay when running with ART and i honestly see no difference except quite a bit of lag when opening apps and a very hot phone. going back to dalvik, less heat,less lag. for the guy that said that ART was fast....well buddy....this phone is already fast and thats without ART. i know its still early in the game for it,but,as of right now....dalvik it is.
Hi!
Is there simple explanation what ART does for regular Joe? Why does Google gives me choice between ART and Dalvik?
Thanks!

Google doesn't give you the option.
Its hidden in developer options for a reason.
To answer your question, it gives you a preview or "beta" build of ART and what's to come. Its a smoother experience and OS seems snappier over all. But with all the optimizations Delvik runtime it not really noticeable. The most notable difference is between switching task and apps. That's all it really offers to an Average Joe.

I guess I'll enable it and see
Can switching between ART and Davlik (with some apps installing/updating on one, others on the other) cause issues?
I just wanna try ART out for a few days on 4.4.2, switch a couple of times for speed comparison, and if unsatisfied, return to Davlik, but only if this doesn't cause issues of any kind.
Does it?

when I switched over to ART, ALL my apps started to crash. But I had a really old PA-gapps package and that was the issue. I did post in the forums and someone told me to use another gapps ( cant remember sorry ) and that mostly solved all my problems except that the keyboard still crashed.
There was a problem with the PA-gapps package. But now, with the new ones, you shud be perfectly fine. Even whatsapp is fixed
1. Improved overall performance(made my 1st gen kindle fire fly, same with nexus)
2. Better battery life ( at least 30-1hr for me)
3. Faster app loading (assuming the app supports art should be noticeable)

Which runtime are you running? Have you noticed any difference?
I tried switching to ART, but every time I restarted my phone it would spend 15 minutes upgrading ~100 applications. I restarted it about 4 times, and it upgraded every time.
I typically avoid ART. It produces random issues on my G2, Nexus 5 and S4. Dalvik for me until Lollipop!

You need to wait it out, it always takes awhile to update all of the applications when you initially change runtimes.
I'm on ART, no issues so far.
Maybe a dumb question, buy how do you switch?

Go to About Phone in settings, then click on the Build number until the toast notification tells you that you are a developer. Then go back and click on Developer Options and then Runtime.

im having same issue when using ART. it optimizes apps (15 of it) every time i reboot, ive rebooted at least 5 times, i think currently Turbo isnt very compatible with ART
Well ART on Kitkat is not even close to ART on Lollipop and ART on Kitkat is experimental so I don't know why people would be surprised when it doesn't work quite right...

Well it worked flawlessly on Droid Maxx, and seemed faster than Dalvik. On Turbo it's always optimizing upon every reboot 15 apps. BTW has anyone else noticed weirdness about phone dialer? It takes several clicks and random presses on the screen to get the keypads to come up...
Did you guys have bench numbers for Dalvik vs. ART?
For me Dalvik seems to be slightly faster:
Dalvik: AnTuTu: 48989
ART: AnTuTu: 47467
Benchmarks do not accurately represent the increased responsiveness in the interface. Benchmarks generally are a pretty poor way to compare real world performance.

We can argue ad infinitum, but benches are still better than a "gut feeling" or "I can see smooth"
Think what you want but ART runs the UI more smoothly regardless of what some "benchmark" says.
So does ART "optimize" on every boot? For some reason I didn't think it did, but when I switched to ART on my Turbo it seems every time I reboot it goes through the "optimizing apps".
I'm using ART just because we aren't rooted, so none of the good root-only apps that are incompatible with ART are an issue.

Same here, that's why I switched back. Whenever it rebooted it optimized apps, and it took a good 10-20 minutes for it to finish. If it was on battery, the battery dropped significantly and the phone got very warm.
I ran both on my Razr Maxx HD, seems to get better battery life, and it seems a bit more responsive running Dalvik. That is just an uninformed opinion. I settled on Dalvik, it just feels nicer to me.
If you want to use ART I recommend doing the switch before you install anything from Google play not after when you have lots of apps installed.
Switched to ART just to see. First reboot optimized 255 apps (expected). Rebooted again, optimized 75 apps. Tried rebooting again and again optimized 75 apps. Anyone have any idea why? I'm thinking maybe it's because Verizon placed so many apps in system/app...

I switched to ART a couple of day ago. Phone seemed to struggle with the stock apps. @bmxerkid954 mentioned that its probably because those apps are not optimized for ART yet. Try it out and let us know your experience.
