ART Users - Opinions - Nexus 7 (2013) General

Hi, if you've been using ART on 4.4 Roms, would you say the increase in speed is real, and have you noticed an improvement in battery life?
I tried ART yesterday and I thought it was incredibly fast, but now I wonder if it wasn't placebo.
I had to revert to Dalvik, though, because Whatsapp doesn't work in ART, but I am interested in people's opinions of ART.

No and no. Everything feels quite the same. I think it's placebo at the moment.

You dont need to rebuild applications except few cases - they will crash anyway on ART.
They just replaced JIT with AOT compilation and threw away Dalvik as its not needed in case of AOT translation anymore.
Well, not yet but they plan to do so.

After I switched to ART I had constant force closes from Gapps to the point of almost having to factory wipe from recovery.

Try odexed gapps

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.

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.

Does it make a difference to ART being on official Kit Kat or is it the same?

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
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.

When I enabled ART
My Nexus Boot looped..
Im running stock 4.4 ota, Deodexed.

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

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.

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.

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

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

Post your custom ROM experiences

I figured I would start a thread since I couldn't find one devoted to posting our personal experiences with ROMs for our Kindles.
I have tried 3 separate roms out thus far.
CM 10.1 (JB 4.2.2)
This was my first dive into custom roms for my first gen Kindle Fire, and it was a pretty easy transition. Really enjoyed freeing up the device by not having to have the stock Kindle firmware. Apps ran far more quickly and smoothly. After using this for a while I yearned for something faster/smoother. (probably need to get myself a higher powered device to improve on that). Somewhat missed the lack of an Amazon Video app. It's too bad Amazon has not yet developed an app for other Android devices that we can install. A minor issue (with all roms) seems to be the boot animation. It starts out stretched and in the upper right region of the screen at first and then corrects itself maybe 10 seconds later and is centered. Not a big deal of course. The only drawback for me personally with this one is CM's lack of customization.
JB 4.3 Barebones
I had read that JB 4.3 ran a bit quicker (and used more battery) than 4.2.2. I found this to be the case. Especially when using an app like Flipboard this is apparent. The boot time seemed to be a bit longer than CM 10.1, but that could very well be my perception. I did find that the build I was on seemed to give me issues on restarts. I'd restart and icons would be missing and the icon themes I was using with Apex would have to be reset. Mild annoyance that I didn't enjoy dealing with. Overall I was mildly satisfied and preferred CM 10.1 to the specific (early) JB 4.3 that I was using, despite the fact that CM ran slower.
AOKP (JB 4.2.2)
Just installed this one tonight. Coming into this, I was already a big fan of AOKP 4.2.2 as its my daily driver on my Droid Razr M. Love AOKPs customization. Anything beyond AOKP level customization is overkill for my taste. AOKP just has everything I'd need in that department. I did notice that I feel like I'm back to CM 10.1 speed which I may or may not settle on. A minor issue I found was the screen rotation glitch (which I have heard is found in few different ROMs.) It's nothing too major, but it may be enough of a nuisance to get me to switch in the future. We'll see. I do prefer AOKP 4.2.2 over CM 10.1 strictly due to AOKPs level of customization. If you are simply looking for a ROM beyond stock and not necessarily looking for great options and customization, I'd say go with CM 10.1 (If you don't have your heart set on JB 4.3, that is). But my personal favorite of the 3 would have to be AOKP. I have not used this long enough to properly test the battery life compared to CM 10.1.
I hope this helps any noobs like me who are giving flashing roms a thought. Would love to hear what you all are finding for the best speed and battery life. I'll post any updates for roms that I try in the future.
Summary:
Best Battery - CM 10.1
Best Speed - JB 4.3 Barebones
Best Customization - AOKP 4.2.2

I'll check it out thanks! How does battery life compare with the others you've tried? I'll take speed over battery life at this point though. So definitely giving it a shot, thanks!
The battery life is around the same as official CM10.1. The battery lasts a whole day with moderate to heavy usage. Performance is about the same too

Thanks for starting this thread! I've been trying find a jelly bean rom that doesn't suffer from low memory app crashes. Like when the browser just quits suddenly and drops you to the home screen. So far cm10.1 and the stock roms have this problem pretty equally in my experience. Has aokp or any other rom better handled this issue for you?

Well just as you mention it, BAM! That's exactly what I'm experiencing now with AOKP 4.3. Lots of browser crashes and keyboard issues where it will not pop up. Rom is still a decent bit quick, but I may be looking to downgrade from JB 4.3 to something that won't have minor issues such as browser crashing. Need a good daily driver with good speed and battery life. AOKP 4.2.2 didn't have the browser crashing.

Basic question, but have you done a weekly wipe of cache and dalvik cache in recovery? May be worth a shot if it took a month for errors. I always do a cache and dalvik cache wipe once a week on my phone. Seems to keep it running smoothly.

I've had my kf for about 3 months and while i haven't flashed them all i have flashed lots of them.
Unfortunately, i haven't found any rom either with or without gapps that have the low memory/ram issue.
I have done lots of searching an just plain tinkering with everything from freezing everything possible in stock roms to only having 2 user apps installed, i.e. dolphin browser and adobe flash player.
The only thing i really want to do is to be able to let my grandson and nefews/nieces watch cartoons on the net, and maybe some simple type kids games. (This way they have their own and dont mess with mine lol)
The games I've found and installed and they work fine, but the memory on this thing is just not capable of even rudimentary multitasking.
Its a damn shame too, because just an extra 50 - 100 mb of ram would make the difference.
Wish i knew how to dev a kernel id look at the big memory kernels on the gnex and see if he same principles could be applied.

I'm running 4.3.1 CM 10.2 and I just can't do it anymore. If I have to downgrade to an earlier version of Android I will. I just need faster.

ROM not room...?

Beans ROM, Hyperdrive, ButterBoost, or Stock.

I've tried all three and really can't decide which one I like the most. Which on are you using and why?
Sent from my Beans Powered N3 using xda app-developers app
I've been using Hyperdrive since the first build came out for Note 3 and the thing I like most about it is the battery life. I unplug at between 5 and 7am and by the time I go to bed at night I'm usually still around 75 - 80%. Of course it runs much smoother for me than stock does and I like the customizations that come along with it as well. I tried to flash Beans last night just to check it out but for some reason it wouldn't boot so I just restored my nandroid. I'm planning on flashing Beans when I get a little more time and checking it out but for now I'm extremely pleased with Hyperdrives performance on my device.
Eclipse
Im gonna wait on Nitro and his fabulous eclipse rom, it will be awesome, right now running stock trimmed out.
Try both and see if you like either one better than stock.
I basically switch everyday cause they're both so good

Might as well do this. With SafeStrap, you can load up multiple ROMS and switch as your heart desires. Honestly, don't know why phones with unlocked bootloaders don't have a Recovery that allows ROM slots. Seems to make perfect sense so you can load up more than one ROM. Just like partitioning your hard drive and running Windows on one side and Linux on the other. You can chose what you want to use, when you want to. Cant beat it.
But to answer your question, I am running HyperDrive since version 1. Havent really tried Beans. Sure it runs just as good. I am just happy with Hyper right now.
Stock with xposed framework and modules. While i appreciate everything the dev's do, development is not far enough along to leave stock with xposed yet.
Also on stock with too many mods in xposed to count. I seriously can't see any reason to flash a rom. I'm consistently getting up to 2 days uptime and I have all the mods I could ever want.

So i struggled for the longest time why one rom on my phone would play nicer than the other , if they both use the same base.
So I formulated a theory , which can be really wrong , so take it with a grain of salt: Currently I have close to 120 user apps and wanam xposed with multiple customizations. I feel like your set is up is the reason why one rom will be buggy with poor battery life and other will be phenomenal. That is why you will find people swearing with one and hating the other. It is hard to find a perfect rom for all, since android varies tremendously due to its wonderful inherent ability to be customized.
of course you can also argue for coding, build boxes and smali skills.
which goes back to the main point, you need to try it out because compatibility between the developer's build and your set up is key to the perfect rom combination
so dont be startled if you try a rom that others rave about and it sucked on your phone , just move on and vice versa.

I totally agree with you there. My battery life on HyperDrive is ridiculous. I can go almost two days before I need to plug my phone in. I'm very satisfied with HD and don't plan on switching anytime soon. I ended up staying on RLS2 cause my theme was causing my phone to reboot whenever I pressed the lock button after I took the RLS3 update, but overall HD is a very solid ROM and I'm quite content with it.
I just recently flashed the newest hyperdrive update RLS3 On 11/27 I'm having problems on the power menu doesn't show the power off also in the very top next to the clock it shows a lock icon what is it there for and can I remove it

ART - Android Runtime

Why isn't possible to enable it? What's the point of getting KitKat without option to enable it?
On devices such as the nexus 5 it is still only available through the developer options and to be quite honest from my own experience (ex nexus 5 owner) I didn't notice a blind bit of difference between ART and Dalvik. In my limited knowledge I believe apps and such need to be optimised to benefit from using ART and very few are at this time. What exactly do you think you are missing out on?

The N5 is already godamned smooth thats why both Dalvik and ART dont show much difference. For lower end phones, ART showed much improved performances like opening applications
Sent from my SM-N9005 using XDA Premium 4 mobile app
I think that ART will fix some situations in which this phone (or any Android) isn't that good. For example, when I try to pitch to zoom very fast when I'm browsing, it isn't smooth at all and it's quite laggy. But just that first second (or less), later is everything smooth. I think it's because of the Dalvik's JIT anf that ART will fix that

ART on G3!

How is G3 performing with ART? Any cons, incompatibility issues etc. Please share your thoughts and experiences here.

Ive switched back and forth and its fine.
I made the switch this morning. I'll update a bit later when I've had some time with the device. I'm using Nova which changes how the device feels from stock anyway but I'll be keen to see if there is any improvement in app switching.

I haven't had any issues with ART and compatibility so far. My phone does get a lot of force closes on XDA's app whether I use dalvik or art it happens 10 times a day. ART sends slightly faster to me but not a huge jump like it's supposed to be.

Little update after all day with art. Noticeable more lags- lg ui, chrome, internet, youtube. In my opinion phone much slower, battery drain much faster, compatibility- all LG apps full compatible ie camera, IR remote.

I'm using art and so far it's working great. Launcher feels a bit smoother and apps open a tiny bit faster.

Barclaycard and Blinkbox Music don't work on ART in fact Blinkbox doesn't even work on Dalvik either.
Xposed doesn't work on ART yet. A few other apps won't either but that will change over the coming months seen as android L will be ART only.

In theory, ART should be smoother and faster, and battery life should be better.
But alot of apps, especially mod app doesn't support ART. I suggest keeping it on Dalvik until the community/google makes the switch.

Exactly; ART is the future of Android.
According to the article on PhoneArena (link given in first post) apart from Nexus, only the KK devices (4.4.0 and newer) having ART option natively in its firmware (2014 devices like S5, M8, Z2 and G3 as well) are to support ART, and Android L in this case, if I didn't get it wrong.

L is supposed to be ART by default.
Curious, have it ever occurred that enabling art actually make the battery life worse?

There's no reason why it would. ART compiles the dalvik byte code on first run of the Rom whilst dalvik does it every time you start an app. To convert it to the machine code uses CPU cycles and therefore more battery and dalvik does this every time you open an app.
The only thing it does is use more storage space as the pre compiled byte code has to sit on the device.

The only way it will make battery life worse is if a core app doesn't work properly with ART and therefore puts more of a strain on the system as it keeps trying to work.
However this would usually give an error message that we can all see to show its not working properly.
That being said, today is my first full day on ART and I have had terrible battery life, but I do not think (yet) that ART is to blame.

Best ROM for battery life and performance?

Last time I ever flashed a ROM or participated in this was about 3 years ago. I'm pretty fresh to how this works and all but i still remember the gist of it. I just got my nexus 4 and am hoping to make it better

ROM will be pretty much irrelevant. The vast majority are AOSP based, with the differences being visual tweaks and added features, which add little, if any, drain on the battery. Some features, like pocket mode, might drain a bit more, but it's up to you to use them. All will run smooth as butter, stock. It's things like live wallpapers, excessive widgets, and apps running in the background that'll cause lag and stutters.
Custom kernels can help with battery life, but it's a small percentage, and it depends more on how you use the phone. A wakelock detector app plus Greenify can keep your phone from constantly waking and syncing, and that helps battery life a lot. And of course, screen brightness is the biggest battery killer of all.

Well if you want a really smooth and battery friendly rom, I'd recommend the L preview.. If you want a Kk rom I'd recommend liquidsmooth as it's feature packed and optimized really well. I personally have used both and right now use LS with Unleashed kernel.. It's a great combo. But in the end you gotta try out doff things to see what you like

I was thinking of install the L preview and matrix kernal! But I don't really know how stable and what bugs are in the ROM and also not many apps will work on L...

So let's say I install L and matrix kernal. When the official update comes out, will I lose root when I update?

Well I doubt you would be able to even install an ota update of the official L.. You'd have to probably flash a new rom based on it or flash the factory image once it's out.. I'm sure rooted base roms of L would come out within a week of the release so you could flash that.. But if you want the ota, then you can go back to factory image 4.4.4 after release of L and get the ota after.. But no root.
