I think/know it is faster. (mostly in listviews)

You can tell it in apps such as XDA developers -> there are no to far less hickups/stutters with ART.

Uups: Thought I'm in the Nexus5 forums,

so my comment is based on my experience with ART + Nexus5.
[Nexus 7 (2013) General] kev0153:
Chrome seems faster but I'm not sure yet. The only app I had trouble with is Ti backup. I'm sure he'll release an update for it.
[Nexus 7 (2013) General] StrangerWeather:
Does it make a difference to ART being on official Kit Kat or is it the same?
[Nexus 7 (2013) General] MidnightDevil:
It does feel a little bit faster. It's gonna take a little while longer until we feel the real difference between ART and Dalvik.

Soon as ART ready apps start to come out, then we might have a show :D

So although I tried it, I went back to Dalvik for app compability reasons. I'll give it a try in a couple weeks or so.
[Nexus 7 (2013) General] JustZaphod:
When I enabled ART

My Nexus Boot looped..

Im running stock 4.4 ota, Deodexed.
[Nexus 7 (2013) General] blackhand1001:
You need to be running an odexed rom to use ART.
[Nexus 7 (2013) General] JustZaphod:
Yeah..

I sort of figured that.. I originally put on the Stock OTA, had everything going well..

Then I flashed a Deodexed version someone shared..

Made a Nandroid backup so if I want to play with Stock.. Ill give it a whirl..

So far I've had no issues, but I really dont see much benefit from upgrading..

I was so looking forward to using the new Launcher.. I might just flash back to my trusty Carbon Rom with Faux kernel.

Ill wait until the kernel source and the Stock image is posted

[Nexus 7 (2013) General] godutch:
Can anyone running art say how much the droidbooster app says the performance increase is? On jb it was 5.5-6 times, I wonder how much increase we can still expect from the flexycore acquisition.

[Nexus 7 (2013) General] martin707:
Modern Combat 4, FIFA14, and Dead Effect all crashed using ART
[Nexus 7 (2013) General] akhan47:
It's hard to notice any differences in speed when using ART, I tried it on my N5 but quickly went back to Dalvik because of WhatsApp being broken,

saying that, I am trying it on my Nexus 7 now. I regularly use the app 'UberSocial' for Twitter. It has always lagged when scrolling through my timeline but I continued to use it because of functionality. After I switched to ART, it no longer lags. No placebo, I use the app frequently enough to notice and it's a huge improvement. Scrolling is WAY smoother than I've ever experienced on this app before now.

So yeah, things are looking promising for Android 5.0.
[Nexus 7 (2013) General] martin707:
True, but you only had your new phone for weeks. I had my tablet for 3 months now. It should be it noticeable when opening and closing apps
[Nexus 7 (2013) General] torchwolfery:
so far

I can feel a difference when using cool reader and i open books that are very large, also when i use adobe for reading sfx magazine its amazing now there is no lag no matter how large the filesize... the only real dissapointment for me was that camera VF-5 doesnt work on art sniff sniff
[Nexus 7 (2013) General] Q8-V08:
2.6 with ART

5.8 - 6.0 with Dalvik
[Nexus 7 (2013) General] netorincon:
Noticeable speed increase

I noticed an amazing speed increase, specially when multitasking. Idk if it has to do with kit Kat or art, but it's definetly faster. Before enabling art, it'd take 1/2 second to switch apps, now it's immediate.
[Nexus 7 (2013) General] lomonic:
Same here and have not encpuntered problems with apps yet.
[Nexus 7 (2013) General] Q8-V08:
http://www.kevs3d.co.uk/dev/canvasmark/

Try that benchmark in chrome, with ART I got 3885 with Dalvik I got below 3000.
[Nexus 7 (2013) General] netorincon:
Weird... I got 2927 with art enabled
[Nexus 7 (2013) General] lomonic:
yeah im 2900 flat :D

maybe i have too many apps opened?
[Nexus 7 (2013) General] Moon.lSd:
Antutu X and Titanium crash with ART :rofl:

Noticable performance increase, Wifi, Original Odex Stock ROM, just TWRP Recovery, rooted.

I think I will use ART for a while, maybe until Android L version.
[Nexus 7 (2013) General] runedrune:
Definitely smoother.

I don't believe in benchmarks but here's for the people that do:

Never done one before so don't know how much it usually gets.
[Nexus 7 (2013) General] godutch:
So we can still expect the biggest boost coming in the future
[Nexus 7 (2013) General] cinco312:
It seems smoother but it could just be a placebo effect. My only issue is I can't install DropSync or 1Weather, two apps I use regularly. Also, I don't know if it's just me but does it feel like it takes longer to install apps? Whether from the play store or sideloading, it just feels like it takes a little bit longer
[Nexus 7 (2013) General] cinco312:
Holy crap! Anyone use Photoshop Touch? It loads up extremely quick, it screams and I had six other apps open. I can definitely see the difference based off this app.
[Nexus 7 (2013) General] stealthj:
My instagram is super fast when scrolling with art runtime instead of dalvik. It took a looong while for my tablet to become usable though when I first enabled it. The touch kept freezing for like 2min when I was trying to type my password in. Its flying now though! I'll switch back though if I notice any more than normal hiccups in certain apps....yet to test them all...
[Nexus 7 (2013) General] cinco312:
Chrome and G+ also are super fast as well. Facebook on the other hand, well nothing can fix Facebook. The Camera loads quick as well. I tested a lot of apps and had zero FC's or any other issues. Really enjoying this.
[Nexus 7 (2013) General] xdhall:
Tapatalk is much smoother/faster using ART
[Nexus 7 (2013) General] akhan47:
Same happened to me on the new Nexus 7. Took a couple of reboots to fix but now the tablet seems faster than it's ever been.
[Nexus 7 (2013) General] StrangerWeather:
Having tried it again I am convinced it is A LOT faster. I would use ART all the time now if it wasn't for Whatsapp not working... :)

List of apps not working in ART - http://androidruntime.com
[Nexus 7 (2013) General] MidnightDevil:
I just hope the *priority* applications are updated quickly to be used with ART enabled. Like Titanium Backup.

I could just restore the apps and switch to ART after, but I tend to swap roms almost weekly, wouldn't make much sense.

I might give it a go, or I might just wait for the updates. lol

Also, Quora isn't working :( I know I could just use the browser but I kinda like the widget :\

After i change the n7 to art, the screen goes insane...super slow and instable.….i havê to change again to dalvik

Enviado de meu Nexus 7 usando Tapatalk
[Nexus 7 (2013) General] NsZebra:
because enabling and disabling art is like changing the ROM, you must wait for all apps to optimize and you must let your tablet settle down for some minutes before you can use it, also remember to reboot after 20-30 minutes of the first boot.
[Nexus 7 (2013) General] StrangerWeather:
Why reboot after 20-30 minutes?
[Nexus 7 (2013) General] NsZebra:
well i know how to explain with dalvik, but with ART it might be the same explanation..

once you first boot the rom will start creating the dalvik cache and optimize the system files, so after 20-30 minutes you can be sure they are all loaded fine, so you reboot to get a common boot with optimum perfomance.

maybe i am not right, but it's what i know.

EDIT:

just remembered something about dalvik, once you clear it (in cwm or twrp) you must wait all apps to optimize and let the device settle for some minutes, then you can use your newly flashed device or just the same rom with cache dalvik wiped.

sorry for the bad english
[Nexus 7 (2013) General] lomonic:
didnt take that long for me. prob more like 5-10 mins. i think the more apps u have the longer it takes but u should see the progress of optimizing apps and the count to total

[Nexus 7 (2013) General] Robin Dhicke:
I was running odexed and I bootlooped as well.

I was 100% stock with no custom recovery or any backups so I had to flash the factory image to get it to boot. Didn't expect trying a feature from an official ROM would be so disastrous
[Nexus 7 (2013) General] Picao:

[Nexus 7 (2013) General] noideaforusername:
It feels faster and smoother and even comes with amazing battery life:
[Nexus 7 (2013) General] ShannonAUT:
What can I say, it really feels snappier (don't know if it is just ART or 4.4 alltogether)

So far I haven't encountered any app that won't work it ART.
[Nexus 7 (2013) General] godutch:
I didn't notice anything, everything works but things felt very smooth, smoother than jb, on kitkat dalvik too
[Nexus 7 (2013) General] MrPhilo:
Animation are a lot smoother. Defiantly not a placebo effect. I can see the difference on both of my Nexus. Scrolling and overall is smoother, opening apps is tad quicker on some apps. Sucks that what's app doesn't work.
[Nexus 7 (2013) General] mi7chy:
Very pleased with what I'm seeing so far. Flashed Kit Kat 4.4 factory image without wiping data with unlocked bootloader and non-rooted stock. Went straight to ART since it sounded very promising.

Running Anomaly 2 benchmark at high quality now gets silver whereas with JB 4.3 it used to get bronze.

Epic Citadel benchmark looks very smooth at ultra high quality.

Dead Trigger 2 runs very smoothly at high quality.

It feels like the N7 2013 got a CPU/GPU upgrade. Just need to go back and compare with 4.4 Dalvik.

Unfortunately, some apps are closing such as Modern Combat 3 and 4 and CoD Strike Team but hopefully they can update them to be ART compatible.
[Nexus 7 (2013) General] stfudude:
Gameloft optimizing their games? Not gonna happen. LOL
[Nexus 7 (2013) General] Summit1:
Yep, I can confirm that Titanium crashes. That's a show stopper for me. Going back to Dalvik. We have to remember that this is in development mode and is still being tested and refined before permanent switch is made.
[Nexus 7 (2013) General] hailang215:
I noticed that RAM used will be little more,about 100MB(maybe),CPU running time declined little,smoother and faster when u tap in and out apps.

ART just compliment with my apps,none of them crashed suddenly(right now).

I had the whatsapp problem too. However, you can install an older version while in dalvik mode, switch to ART, and it works! Let me now if you want the app... PM me. It wasn't my fix so I'll give credit to the guy who helped me.
[Nexus 7 (2013) General] StrangerWeather:
Cool, which version is it?:)
[Nexus 7 (2013) General] murad052:
Kitkat is much smother than 4.3.1 but ART and Dalvik we cant compare them now cuz developer still didnt modified there apps to take the advantage of ART so no winner here

about the battery life not that much to be onset . but i will update more about it later.. to give it more time

can you guide me how you make whatsapp work in your nexus .. by the way i have N7 2013 LTE
[Nexus 7 (2013) General] mi7chy:
Just a quick update. I switched from ART to Dalvik, cleared Dalvik cache from recovery, reran Anomaly 2 benchmark and it dropped back to bronze at high quality. Also, things didn't feel as snappy. Seriously thinking about giving up some non-critical apps for the time being to benefit from ART performance boost while encouraging developers to update their apps. Funny thing with Gameloft is that Nova 3 runs fine.
[Nexus 7 (2013) General] TheGoD:
Any chance to get ART work alongside Dalvik on a per app basis? Maybe the Xpose framework?
[Nexus 7 (2013) General] Tim4:
I believe thats the solution google will provide later, because some apps will never work on ART just because of the way those apps designed (Dynamic code) and limitations of AOT compiler.
[Nexus 7 (2013) General] mawells787:
Maybe I'm in the minority but I'm having touch issues when I switch to art. Never had touch input issues before kit Kat and while on dalvik touch is fine.
[Nexus 7 (2013) General] bcvictory:
Does anyone have ART optimise apps on every reboot? It happens to me and is really annoying! I don't even change anything that would wipe the cache! Does this happen to anyone else or any ideas what I can do?
[Nexus 7 (2013) General] cinco312:
No, never happens with me. The only thing I can suggest is wiping the cache in recovery, let it optimize, then see how it goes.
[Nexus 7 (2013) General] bcvictory:
I will try that now. It's really irraiting me to wait 30 minutes every time my device crashes or reboots.
[Nexus 7 (2013) General] cinco312:
Yeah that would piss me off too.
[Nexus 7 (2013) General] martin707:

HOW TO GENERATE LIBART.SO FIX

1. Apply the patch from cernekee's github to your AOSP tree

2. "make dex2oat" from the top level

After using kitkat with art for a while I have to say my n7 now feels a lot smoother than my HTC One, I never really noticed this before, in fact I always thought the One was smoother than the n7 but not so anymore. Still don't know if it's just kitkat or art or both.
[Nexus 7 (2013) General] RKight:
I don't know if it's ART, or 4.4 in general, but my battery life is way better. On 4.3, I could leave my N7 sitting around in sleep mode for two days and go through 50% battery without even touching it. I've had it off the charger for almost three days and have two hours of screen on time, and this screenshot shows there's an obvious difference.

[Nexus 7 (2013) General] RKight:
Okay...the screen shot didn't seem to work right. It shows up tiny for some reason. Anyway, I'm at 2 days, 17 hours off the charger, 2 hours of screen on time, and sitting at 64% battery. I'm happy.
[Nexus 7 (2013) General] VA3DBJ:
I have been running ART for about 4 days, and I noticed that it seems to run a bit smoother and I actually got an extra 1.5 days of battery life. I have also noticed that on my rooted phone, ART did not co-operate to well with apps that required root.

[Nexus 7 (2013) General] cowisland:
Maybe it's just me, but I have not noticed any difference with ART. Everything was smooth to begin with, remains smooth with ART.

On a separate note, It looks like Tasker no longer turns off wifi when the screen is off as it is supposed to. Not sure if that's due to 4.4 or ART.
[Nexus 7 (2013) General] StrangerWeather:
Well, after using ART for about a week I reverted to Dalvik because I use Xposed Framework which is not compatible with ART.

The difference is amazing. I now find Dalvik really slow compared with ART. Every app takes at least a second or two to open when it was almost instant with ART... I think once one is used to ART it is difficult to go back to Dalvik...
[Nexus 7 (2013) General] onesolo:
I don't think that ART as anything to do with it...

I don't have ART enabled on "my" N7 II, but I feel that I'm getting on 4.4 a better battery life, between 30m to 1h of screen time extra.
[Nexus 7 (2013) General] wintermute000:
not running it long enough to notice battery life, but apps are definitely opening quicker and scrolling in chrome is definitely smoother. None of the apps I regularly run have issues. +1 from me
[Nexus 7 (2013) General] cowisland:
Just to clarify, does ART compile apps into native Linux code at installation time? That would be great if true.
[Nexus 7 (2013) General] Tim4:
ART compiles whole byte code during installation (AOT compile)

Dalvik compiles required code during execution. (JIT compile)
[Nexus 7 (2013) General] cowisland:
Thanks. After reading a few tech blogs like this one

http://www.androidpolice.com/2013/1...-in-secret-for-over-2-years-debuts-in-kitkat/

It looks like ART pre-compiles apps into native (Linux) machine code instead of Java byte code that is then (slowly) run by Dalvik. When fully implemented this should be a great improvement in efficiency for Android, which, at this point, mostly means better battery life for high end devices and smoother performance for mid-range devices.

Interesting in any case, and from my end-user perspective the greatest advancement since the use of GPU for UI rendering in ICS.
[Nexus 7 (2013) General] Tim4:
I believe its kinda wrong.

CPU cant execute java/dalvik bytecode, therefore dalvik converting the code on the fly into asm. As i understand originally they did it to decrease memory requirements and increase compability.

And ART converting whole code contained in .apk during installation so it doesnt waste power during execution of program.

ART is not faster, its has less lags/stutters.

Switching to ART Question

Quick question about switching to ART. I'm stock rooted and other than TiB after reading through this thread shouldn't have app issues. I am just wondering if there are issues using the GEL and if I have to set up my home screens again like when I switched to the GEL? Any thing I should do before turning ART on?

Thanks,

fasthair
[Nexus 7 (2013) General] prstorero:
Titanium works with art now. I used art for a while on my tablet (always use it on my phone), but switched back due to the few games I play not working. I didn't have issues with GEL. You may have to set up the screens again. Use titanium to backup and restore the app and it may save it (I'm not sure if it's stored in that apk or Google now since they're intertwined). Before switching it on make sure you're running odexed ROM and gapps ☺
[Nexus 7 (2013) General] fasthair:
Thanks for the reply.

After I posted this I did some reading and seen TiB had been updated. I'm on the stock ROM so I should be good to go there. This is more a curiosity killed the cat thing wanting to try ART more then anything and since don't really game on this thing that's not an issue for me.

So I guess I'm going in...

[Gen8, Gen9, Gen10 Q&A, Help & Troubleshooting] woodspire:
I am new so I cannot post this in the developper section.

Please repost it there for me.

I have an Archos 101G9 Turbo with 512Mb RAM both on woot dot com a while ago.

Last night, I installed [ROM] [4.3.1] CyanogenMod 10.2

works perfectly; faster than the previous ICS rooted ROM.

GPS seems to work, camera is OK (not nice picture but at least work and with color).

Sound works.

Didn't test the MIC, bluetooth and USB mounting.

I tried the 2013-11-08 build.

The HDMI does not seems to work.

I tried to change the HDCP settings in the settings app, but I still get nothing on my TV and it was working with the ICS rooted ROM.

Did anybody can confirm my finding ?

I think the problem might be that the Archos 80G9 does not use the same HDMI chip as the 101G9; so the driver could be missing from the build.

I say other custom ROM having problems with HDMI, so maybe we could check what they did and it might help.

Will test the MIC, bluetooth and USB mounting (from the mini-usb connector, not the full USB port) today.

I have no 3G stick, so I cannot test the USB port. (and really don't care, except if someone can active it as a full USB port)
[Gen8, Gen9, Gen10 Q&A, Help & Troubleshooting] woodspire:
bluetooth does not work

MIC works. SD card R & W works.

external USB via NTFS mounter R & W works (superuser root access works)

but bluetooth does not seems to work. It cannot find my Pebble watch and my old ROM was able in the past.

Anybody can test the bluetooth on Archos 101G9 ?

Also I have and 8Gb version, not Hard Drive.
