I tried the Moto-X dalvik and still noticed lag which I don't see using ART.

Edit: I just noticed that I flashed a kernel in between testing. Tried again and the moto-x dalvik is smooth and not noticing lag anymore. I like ART but I like xposed more ?
[Nexus 5 General] aeppacher:
What benefits are you talking about when you talk about xposed, just out of curiosity
[Nexus 5 General] dazz87:
DAMN had to switch back to Dalvilk cause Dish anywhere not working on ART
[Nexus 5 General] thegr8anand:
Very impressive and think once dev start writing with art in mind we will see similar real usage improvements like in benchmark scores.

Would love an app that compares your installed apps to check if they will work if you use ART.
[Nexus 5 General] AndyCr15:
I think in the information of the video, there's a link to a site that lists loads of apps and if they work with ART or not.
[Nexus 5 General] thegr8anand:
Yeah i'm looking at it already. Just wanted something easier for the lazy me :silly:

Hi,

Here it's a good start: http://androidruntime.com (bookmark it).

No problems here. I use bluetooth 24/7 with my pebble, and my jawbone in the car and have no problems with connectivity.
[Nexus 5 General] nmlssit:
Edit: On Dalvik we used to perform a wipe of cache\dalvik in order to upgrade ROM and\or Kernel, what to do on ART?
[Nexus 5 General] Knight77:
Which kernel? Just to know...
[Nexus 5 General] paul_one:
Heya guys,

Just wondering if I can use the dalvik runtime once I've booted up using ART or whether a full restart of the phone is required.

I would have expected to be able to launch applications using the older runtime under the newer runtime - after all, it's only a couple of environment variables isn't it? (PATH/LD_LIBRARY/etc)

I suppose it may be a bit more complex, but I would have thought you could chroot or in some way encapsulate the old runtime - afterall the underlying kernel is still the same and the runtime is just a binary VM.

*SO* my question is:

Do I need to reboot my phone to use 1 or 2 apps, or when ART comes to try and compile the package and fails, does it then revert to the old runtime for that package?

Cheers.
[Nexus 5 General] Dan1909:
When you switch runtimes it forces a restart of the phone, and then when it boots up again it fully recompiles (probably the wrong word, but you get the idea...) each app to work with that runtime. So without some pretty advanced and careful modifications, it's not possible to do what you want to achieve. It's very much an all or nothing style system with ART at the moment.
[Nexus 5 General] my2sense:
I was testing the n3ohammer kernel. Franco's kernel didn't have any lag but didn't get as good battery life as the n3o kernel.

The lags were happening on both dalvik and ART and that's how I figured out it was the kernel.

[Nexus 5 General] Knight77:
BUT without MotoX patch...
[Nexus 5 General] italia0101:
Moto patch is something different ,
[Nexus 5 General] davwman:
I take back my previous statement about dalvik patch vs. Art. Art is noticeably faster with better battery life. Only issue is titanium backup not working.
[Nexus 5 General] thegr8anand:
I have been using it since yesterday. ART is noticeably faster in usage. Loving it.
[Nexus 5 General] Dan1909:
I think what he meant is he'd like to see a comparison between ART and dalvik, when the MotoX patch has been applied to the phone.
[Nexus 5 General] uh60james:
Same here, I have no app issues and it is just buttery smooth. Not that the Nexus 5 wasn't buttery smooth in the first place. If it weren't for having a Pebble on my wrist that causes a bluesleep wakelock I could probably make it two days on a charge.
[Nexus 5 General] jspike397:
Art seemed far faster than dalvik runtime, but u had to switch back as Pandora does not work. As soon as more apps gain support for art, I will be switching for good.
[Nexus 5 General] wideasleep1:
Huh? Pandora working fine for me...been running on ART for 3 weeks now.
[Nexus 5 General] gado45:
great explanation! very clear, thanks
[Nexus 5 General] jspike397:
I will try Pandora again, maybe it could of been something else. For everyone who uses titanium backup, it has just been updated with art support.
[Nexus 5 General] indianajonze:
so it looks like titanium backup was updated today to support ART...
[Nexus 5 General] maxpower7:
I realize that Quadrant is mostly meaningless but......

as a means of illustrating how much of a difference ART makes in performance, check this out. I was getting mid-6000s on Dalvik.
[Nexus 5 General] h0lyc0w:
Fantastic. Titanium backup is working again. All the more reason to continue using ART.
[Nexus 5 General] bwells88:
I see this question wasn't answered so I'll ask a different way... Should you pop into recovery and wipe Dalvik after the switch?.... Or is that unnecessary?... Just curious... ?
[Nexus 5 General] Mevordel:
No, everything is handled for you when switching. As far as I can tell, ART still uses the Dalvik cache directory for its files because wiping it gets you the optimizing apps screen.

[Nexus 5 General] Peanuts.:
I'm not sure I'm on ART or not. I'm assuming not because after selecting "Use ART" in the dev settings. Phone reboots. But it still shows dalvik in the dev settings.

*edit*

Just found that Xposed is causing this. :thumbup:
[Nexus 5 General] samflorin:
Same here. Had to completely uninstall Xposed for Art to work.

Update:

From http://xdaforums.com/showpost.php?p=47771876&postcount=5621 :

So bye bye Xposed.
[Nexus 5 General] Ben36:
Can you then re install tho?
[Nexus 5 General] samflorin:
Check my updated post. Art+Xposed is currently a no-no. Possibly never.
[Nexus 5 General] Seadra:
Internet speed Lite/pro crashes on ART, Have mailed the dev, hope he adds the support for that :)

mx player pro is also not working :|
[Nexus 5 General] netpc02:
Wow art mode is much faster than dalvik(got moto x patch)... I can say there is no lag or delay or something. Bye-bye dalvik.
[Nexus 5 General] Raverbunny:
Odd, I use Mx player pro and it works fine for me, stock rooted krt16s.
[Nexus 5 General] Ben36:
Dvalik it is then! Cus there's no other way to have quick settings
[Nexus 5 General] enakeprimen:
I flashed my galaxy tab p1000 with cm 11 alpha release and enable the ART, I notice that ART is much faster than Dalvik.

Yes WhatsApp crashes when opening it and Molto (email app) crashes as well. Flipboard crashes when log in to the account :D

Tried to install Google+ app from Play Store, it said "Your device isn’t compatible with this version" WTH :D
[Nexus 5 General] jspike397:
Everything works on ART, better battery life, and A lot faster, and improvement in every way. I do not see any reason to not switch over to ART unless a app that you absolutely HAVE to use is broken. Everything works for me.
[Nexus 5 General] maxpower7:
Seconded. It's noticeably faster, and I haven't had any app compatibility issues at all yet. My battery life has also been ridiculously good since I switched to ART, even better than my GS4.
[Nexus 5 General] Han Solo 1:
ART doesn't support Titanium Backup?

Keeps crashing when I try to open it. That's a major deal breaker for me. Going back to Dalvik.
[Nexus 5 General] wvcadle:
You mean TiBu doesn't support ART, not the other way around. Anyway, TiBu is updated and supports ART now.
[Nexus 5 General] Han Solo 1:
Great, thanks!
[Nexus 5 General] Dirk:
I've switched to ART, back to Dalvik and finally back to ART again to make sure, but the battery life on ART is definitely better! My daily phone use is always the same and on ART i'm saving 10-20% Battery compared to Dalvik.

I've been playing back Podcasts using Doggcatcher constantly for 11 hrs now and my Battery is at 70%! :good:
[Nexus 5 General] Seadra:
Naah man, it crashes. even this site says http://androidruntime.com/ mxplayer pro doesn't work. So, m confused.
[Nexus 5 General] wideasleep1:
Free version working here..at least with vids shot on my phone.
[Nexus 5 General] Seadra:
yes, free versions works.
[Nexus 5 General] wideasleep1:
So far the only app I've found that I sometimes use but certainly don't miss is xbmc for android. All my dailies work great.
[Nexus 5 General] new ion?:
For me, ART causes the Google Search app to not allow the phone to sleep. There will be a "keep awake" counter of like 16 hours at times. Dalvik: sleeps like a baby.

I have absolutely no idea why I'm having these issues while everyone else is saying that it's improved their battery. I've turned off all Voice monitoring on the search app, turned off location settings... IDK. Back to Dalvik for me for a bit I guess.
[Nexus 5 General] TheLastSidekick:
I've been the one to mess with build.prop tweaks and init.d tweaks since I've gotten into Android and here's what I have to say about both at the moment.

Dalvik - more stable, we know most of the tweaks for it as well.

ART - is MUCH faster but where it fails is of course stability and we

don't have much knowledge of its parameters or tweaks.

Between them both, I'm having a trouble differentiating battery life. Heads up for anyone running Moto X binaries...don't switch to ART you will bootloop. These libraries were only made for dalvik.

All in all, I'm sticking to Dalvik until ART becomes more up to par for stability.

​
[Nexus 5 General] wideasleep1:
What indicates stability? Phone has been on for days, no FC's on known compatible apps. KK itself is an upgrade and all sorts of apps suffer from OS upgrades...especially abandonware. I've found ART to be surprisingly robust.
[Nexus 5 General] TheLastSidekick:
Don't get me wrong I love ART its amazing for how long its been out. But I noticed I do get weird and random process closing errors. It seems to act different for everyone my guess is because not everyone has the same apps installed.

​
[Nexus 5 General] wideasleep1:
Good deal...I was just recalling how few apps have made it through all the generations I've run since Cupcake. I'm used to upgraded breaking apps and often it's an opportunity to find something better anyway. :) I've pared down to less than 100 apps because devs have really begun including addition features and the kitchen sink...which is fine until it too breaks! :p
[Nexus 5 General] Raverbunny:
I don't know what to tell you, I've watched some mkvs just to make sure, everything seems to run fine here.

Just to confirm, I'm on stock rooted KRT16S Nexus 7 LTE running ART.
[Nexus 5 General] wirelessFREAK:
I heard that grooveip doesn't do ART, do any GV data apps do ART?
[Nexus 5 General] new ion?:
Nevermind, it does it in Dalvik too.

Seems that when I kill internet connection it tries to sync and just keeps the phone awake.

New launcher methinks?
[Nexus 5 General] n2rjt:
I can't upload photos to Facebook today after switching to ART. Is it ART, a new FB bug, or just me? I don't know yet.
[Nexus 5 General] Stylez Ray.:
I decided to give ART another try now that Whatsapp is working and I am pretty impressed so far.

Everything is smooth as butter, no FC or reboots. All my apps I need are working just nicely, performance wise it's a keeper.

Can't tell anything about battery life as flashing almost everyday makes it hard to judge.
[Nexus 5 General] Rusty!:
I too have noticed this, however I switched to ART and updated Facebook beta at the same time, so it could be either.
[Nexus 5 General] vs0587:
I's possible to return to dalvik (from ART) withou a wipe? If yes, I'll give it a try....... :silly:
[Nexus 5 General] Dan1909:
Yes easily, just go back into the developer options an reselect dalvik. The phone will then reboot and be back on dalvik.
[Nexus 5 General] n2rjt:
Either way, it's a Facebook bug. I'll report it.
[Nexus 5 General] Seadra:
How come whatsapp is working? I tried ART yesterday and whatsapp wasn't working so I switched back to dalvik. Anyone can confirm this?
[Nexus 5 General] MrPhilo:
ART is working fine for me with Moto X binaries
[Nexus 5 General] gasgallo:
First disinstall your version, then download and install 2.11.50.

This works pretty good

Any problems running or flashing custom kernels on ART?

On ART, is it still recommended to wipe cache/dalvik cache (using TWRP) when flashing a new kernel?

I am currently running stock rom with Franco's kernel
[Nexus 5 General] Rusty!:
If you're using ART then the Moto X binaries aren't in use.
[Nexus 5 General] dark_ente:
Use a custom lib posted in the whatsapp thread under app section. Now you can install latest version of whatsapp
[Nexus 5 General] plien69:
The latest FB release seems to have introduced an ART incompatibility. Switching back to Dalvik solved the photo upload problem for me.
[Nexus 5 General] maxpower7:
I haven't had any issues uploading photos to FB and I'm on ART.
[Nexus 5 General] MrPhilo:
I know, but you said don't use ART with Moto X binaries
[Nexus 5 General] carlese:
Hi guys.. can you please post the whatsapp version that works? do i just need to install that or should i instal patched libs too? thanks!
[Nexus 5 General] greatgoogly:
What version of Facebook are you running. I've found that Facebook 4.0.0.3.3 will not allow photo uploads when using ART, when using Dalvik it works fine. Worked fine previous to this latest version... Oh well another reason to use Google+ more. The Facebook app is a true piece of bloatware that uses an incredible amount of memory.
[Nexus 5 General] maxpower7:
3.9, the latest version in the Play Store according to my phone.
[Nexus 5 General] greatgoogly:
There you go, I'm using a beta. I guess we'll find out whether Facebook fixes it before general release. I wouldn't bet on it though.
[Nexus 5 General] carlese:
Up please.. Working or not?
[Nexus 5 General] Calkulin:
Anyone else get deodex working with ART? Cause I just did. Some mods requires a different approach but I got everything working just fine

[Nexus 5 General] dark_ente:
I just posted the solution 2 posts above your original post.... Seriously some people never read...
[Nexus 5 General] carlese:
Yes I read it.. But someone says that after installing you have to use stock libs again, some keep the custom libs.. It's a bit confusing..

That was exactly what I did (actually the exact same thread I got the patched library from), but Whatsapp still wouldn't install.

EDIT: I was able to install it through adb manually, not sure why but all is good now.
[Nexus 5 General] Rusty!:
You never need to wipe any cache, ever. It's a placebo.
[Nexus 5 General] rg400smarttowel:
Honestly, I have tried it and I can't really see a big difference. It might make my phone 0.001 sec faster but in real world applications, you just can't tell the difference.
[Nexus 5 General] Rusty!:
It's not a case of 'don't use them', you can't use them. Moto X binaries are for Dalvik, and ART is ART.
[Nexus 5 General] meangreenie:
The motox patch has bionic enhanced libraries too, not just dalvik ones. Worth using if on stock or a rom without them imo.
[Nexus 5 General] Technecium:
Apart from enabling ART, is there anything else you can do with it? Are there any configuration options?
[Nexus 5 General] namartlu:
Using droidkang v9 plus elemental kernel, whatsapp works with art automatically.
[Nexus 5 General] nexusmaniac:
Has anyone tested the difference between ART and the moto x dalvik enhancements?

I've been using ART for a bit now. Definitely a noticeable responsiveness improvement not to mention battery during sleep is much increased.

Don't know if it just depends on the phone or faith but the most noticeable improvement to me is the disappearance of in apps stutterings. Scrolling is just buttery smooth :)

The slight difference between recent apps switching, and me not having app compatibility issues, ART is what I use.
[Nexus 5 General] EmperorX:
Just so I'm not mistaken... It was concluded that art breaks photo upload in the latest Facebook app on the play store (not the beta). Is this correct?
[Nexus 5 General] daleski75:
Yes that is correct and the second you switch back photo upload works on the latest facebook beta's
[Nexus 5 General] EmperorX:
Hmm, I am not on the betas but I got an update this morning. Photo upload no longer works...

Oh well... Guess I won't be uploading photos for awhile :(

Stupid Facebook

You said if you switch to ART with Moto Dalvik you'll result in a boot loop, which I did not.
[Nexus 5 General] Rusty!:
I didn't say anything of the sort.
[Nexus 5 General] -A-P-M-:
Delete Whatsapp when you are on ART, revert back to dalvik and install it in Play store. I did that and it works on Dalvik.
[Nexus 5 General] lolcopter:
for starters, my apologies if this has been asked before but I did not find anything upon searching this thread

QUESTION: when switching from DALVIK to ART, is it better to do a fresh install of the ROM and install all the apps once the coversion to ART has already occured? (wipe, fresh rom install, covert to ART, restore apps) OR, is it just as fine to have everything already installed under DALVIK, then convert to ART afterwards (and presumably everything works aside from individual app/ART compatibility)??

Right now, the system finished the reboot and it is optimizing all the system apps and Gapps to ART. Presumably this would just do the same thing for any previous user apps that were already installed. I guess I just wanna know if it's a time saver to do it one way or the other. I'm going to attempt a fresh reinstall of all user apps [under ART runtime] via Titanium.

Given the lack of immediately available information on the subject and the lack of system errors/warnings when doing the runtime conversion, I'll assume both ways is probably fine. Just wanted to know if anyone had any further info on the subject.

Thanks

edit: just off the top of my head right now it seems like converting an already existing setup will probably save the most time on the back end, as you won't have to deal with setting up homescreen/icon layout, widgets, resigning into apps, etc. again.
[Nexus 5 General] maxpower7:
It takes probably about 5 minutes for my phone to switch from Dalvik to ART. It takes much longer to set up a rom from scratch.
[Nexus 5 General] LNJ:
More like 20 mins if you have a bunch of apps installed.
[Nexus 5 General] maxpower7:
I used to have a ton of apps installed, until I realized that I never use anything outside of a core group of a few.

Hey, could any one of you guys make a scrollling comparison with the art on? I am really wondering what a difference it makes in apps like Facebook, Google plus and suchlike.

Every one review of the Art I have seen on youtube seems to just stupidly focus on opening and closing apps, which is undoubtedly not all Art is about.

Or if you guys said made some word comparison between the two, it would be great!

Not much difference since it's mainly the os that runs art/dalvik. Mainstream apps once started can use different code.. C,C++, asm ect... Though they may be affected by background operations in the os.
