Should ART be the Default Runtime? - Nexus 5 General

Hi everyone.
There has been rumours of ART becoming Androids default runtime for some time now, possibly replacing Dalvik.
What are your thoughts on this? What would be the advantages and disadvantages? Do you think it will completely replace Dalvik or do you think that Dalvik will still be accessible through developer options?
Share your thoughts and opinions on this down below!

It's still in a developmental stage. It isn't ready for mainstream yet. There's already an ART / DALVIK thread, possibly two.
Here are the main arguments you will hear;
-ART has better battery
-ART runs better. (Smoother UI, etc.)
-ART isn't compatible with all apps. Some will not work with ART runtime.
-ART doesn't support Xposed Framework at all. Can only be run on Dalvik.
I think you will still be able to select runtimes UNLESS Google finishes it, completely replaces Dalvik with it and abandons the Dalvik source code completely like they did with Tablet UI in 4.4+
There you go.

I mean when and if ART goes mainstream. I've tried to search for threads and I always do before posting, and nothing came up except ART vs Dalvik threads, which is not what I'm trying to make this thread.
I've experienced bad battery life with ART, and I wanted to see if it was the same for other people too.
Also, it can be debated that ART runs smoother than Dalvik with optimizations. I wanted to get peoples opinions on which runs smoother, because of these optimizations.
Some people might run into different compatibility problems then others. For example, 20 out of 100 apps might not be compatible, and for another person only 2 apps might be affected by ART compatibility issues. This means some people will be better off with ART then others, and I wanted to hear the peoples experiences on that as well.

Isn't ART simply Google's attempt to get rid of Dalvik and avoid Oracle's lawyers? They've also been fairly explicit that ART is intended to replace Dalvik, going so far to state as much on their website. I really don't see what everybody's interest in this is. It's a nuts-and-bolts, behind the scenes change really that only matters to actual developers creating apps and should be all but unnoticeable to end users.
Please note, in Android 4.4 a new virtual machine - ART - is being introduced experimentally that will eventually replace Dalvik. Please see Introducing ART for details.

I didn't realise that they were actually gonna fully replace dalvik, I just thought they were rumours. Its all about performance difference as well as battery difference. Which one works better for their needs. These are just minor differences but for us geeks it counts. Also, without threads ect. It would be more difficult to for ART developers to find bugs. We are the BETA testers. All of these threads are like reviews of a product. And they can use these things we say to make their product better.

LoL. I hope you don't really think you or any one else here is a beta tester of any kind. Lets be honest here.. they don't care what you or I think of the new runtime. It WILL happen and the ONLY reason its even accessible is for app developers to get their apps compatible ..
Honestly .. for now unless your an app dev. You should just leave it bee. Its unfinished for the end user..
and the differences vary so much from person to person as far as speed / battery life are concerned I lean more towards there really isn't one and differences you see good or bad are pure placebe..

I think it is reasonable to expect ART will replace Davlik in the next major Android release. The current version on KitKat is probably 5-6 months old. They have surely improved it internally since then. They wouldn't provide ART in the production version of Android if they didn't plan on replacing Davlik completely at some point.

Why do people claim ART is unfinished?
If the app is incompatible then it's the app developers fault not a problem with ART!
Only a handful of apps didn't work with ART initially and that's not Google's fault considering the majority worked without a rewrite from the get go....

I do not think that this thread is even relevant and supporting most of ppl here I would just say - it IS HIDDEN at developer options. That should explain most of things. Switching to release version of ART might also mean major bump in android API level for some developers since they start target ART, which might cause effect of dropping support of everything below 4.4. I will notice to you that vast majority of devices are still below this point, and usual target API is 8-13(i might not remember levels right but basically most of apps targeting android 2.7++ right now). Of course, Google preserves most of backward compatibility, but different VM still means different instruction sets optimized for certainly particular VM.

Art works really well for me both in terms of battery and performance... They should make it default with 4.5

This is what keeps me from trying it fulltime. The fear that its hidden in developers option. I just got this phone and would rather not deal with having to get it replaced because my phone happens to be the unlucky one that can't handle art and dies on me.

Again it is all based on your personal user experience. For me, sadly, about half of the apps failed to run on art. Another half may experience instabilities, for example quite popular game BananaKong was crashing every 2-4 banana runs. Most of modified apps doesn't seem to work with art also. Art will be fitly and nicely at 99% user experience forecasted by me around android 4.8-5+ This is not a poll. It is fact of overall instability, not particular cases.

no not until its optimized

I remember when this phone first came out and reading people switching to art and either the phone bootlooped , soft bricked, or they had to fit it another way. I have nothing against it and its MY personal preference but I'd rather wait until Google gives the all clear.

4.2 Worst ever update?

I haven't updated and have no plans to do judging by the sheer amount of complaints on here about 4.2, i don't recall ever reading so many people complaining about an update as bad as this before and it begs the question, what were Google thinking releasing an update that was so bad with so many bugs,etc and mores to the point can anything be done to fix it?

Hummm Yet again.. I think 4.2 does have some bugs.. I also think its thrown the developers into a Nightmare because of the multi user configuration. Same with apps now having to make storage location choices.. With that said its NOT Terrible.
Obviously you never used the first Version of Honeycomb.. Then the Update Update update .. that still ended you with a slow sluggish interface that Well i Will not go on . Other then to say Google was to embarrassed about it they would NOT RELEASE THE SOURCE . That was bad..
Be thankful Google always pushes the Bleeding edge of there designs.. It brings us new features and keeps our Devices fresh. The update bugs is the price for this . Thank Google.. While Telling them they have Trouble. NO reason to tell us WE Already know...

I haven't bothered with the multi user aspect and it has been fine here. I think its a given that it ain't quite ready considering it was not implemented in the review units.
One thing I noticed is that you can now say "flu shot Monday at noon" and it will finally create a calendar event. I wonder how many more commands have been added.
omg was that monday as in tomorrow or last monday.. I Can not believe i missed the flu shots again.. grrrrrrrrr .. now im doomed
4.2 seems to be working fine on my nexus 7 so far. Even ice cream sandwich had a whole bunch of more serious issues on a number of devices yet overall most people think it was a great update.
I wouldn't say 4.2 is an awesome update as I've only found a couple of changes useful to me. But I just haven't experienced anything majorly wrong with it either. Give it a month or two and I'm sure the niggles will have been fixed as I have a suspicion they could be mostly ap related.
no its a good update, jeez everyone should quit complaining about now.
Worst update ever was the one my flyer got from Gingerbread 2.3.4 to Honeycomb 3.2....
I like it and am happy Google is stepping up. PA is a fantastic ROM and they did some amazing mods. Unfortunately I have a touch of the OCD and would spend hours trying to set it up just right. I was satisfied from the get go after 4.2 was installed and didn't feel the need to adjust any tablet or phablet settings. With the exception of the usual mods CM or AOKP style. Can't wait to see what's in store for this update Dev style!
I too am happy with 4.2- can't compare it to much but it's clearly no disaster.
I myself have not had any issues with 4.2, thus I'm rather pleased

4.2 update
I am new to the nexus family. I got the nexus 7 16gb yesterday and updated it to 4.2 as soon as possible. So far so good.
I've noticed some lag but overall I like the update, astro sees duplicate storage locations but I'm sure they'll fix that. I don't have multi user enabled and am stock, not rooted.

Rom fatigue

I've been flashing roms for almost 4 years now on almost a dozen phones. My go-to rom has always been CM, and for a while I was flashing all the nightlies for this phone and setting everything up from scratch every few days.
But a few weeks ago, something dawned on me: after untold hundreds of rom flashes, I think I'm actually tired of doing this. With all the unresolved data issues on AOSP roms and various other minor problems, I suddenly couldn't bring myself to modify my phone in a way that would actually remove functionality. I've now been on stock rooted MF9 for going on a month, and other than the inevitable 4.3 update, I don't think I'll be flashing any more roms on this or any other phone.
I've been a die-hard rom flasher for almost as long as I've been using Android devices and I certainly didn't see this coming. Has anyone else experienced this?

Yep same here ive flashed thousands of times. About a year ago on my s2 I had aosp . Well we got lost the kids were screaming gps didnt work and data speeds were awful. I flashed back to stock or stock based and everything was great. At that point I realized stick with stock. I will say that the touch wiz based roms here are wonderful. I feel you on fatigue. I've been on sacs rom for a long time and don't plan on changing it.
I'm with you. I got sick o of flashing roms all the time too. Been running stock for a about a month now.

I feel the same only have flashed a couple Roms and am also just sick of always setting up new Roms. Just find one and stick with it I am on sacs. Was on Slim Bean but sacs is amazing and its TW based so don't have to worry about all the bugs that Aosp brings. But I gotta say Slim Bean was solid. Stable build 1 everything was working data ,GPS ,mms I had no problems. I remember just flashing every single ROM that was available back in my OG Evovdays.

That's kind of how I am. I still compulsively check XDA every day even though I never flash anything anymore. It's just really nice to have a phone where everything works. MMS is a good example of something that I don't necessarily use all the time but it's nice for it to be functional when I need it. I suppose I'll probably give KitKat a spin when the roms start rolling out though

This is so funny. I must have tried 50 ROMs on my various phones in the past few years. So many have claimed “visious battery ilfe! Screaming speeds!!!! This will make you cry with tears of joy!”
And then they run about as fast as stock, often with worse battery life, and with broken functionality.
There were some exceptions, like MeanBean on the Evo LTE, and a few others which ran pretty much flawlessly, but switching back to stock always makes me think, “wow, this is not any worse than that custom ROM I just had – a little uglier, but stock runs better…”
(Of course I always appreciate the hard work, and it is fun experimenting.)
Stock runs great on the gs4. Over the last 4 days I've averaged 15.5 hours on time with 3.5 hours screen time. About 70% on WiFi and 30% 3G

I've also never experienced the outlandish speed and battery claims of so many of these roms, including Mean Bean which I never found to work as flawlessly as advertised. Honestly, I think a lot of it is just placebo effect.
I mean no disrespect to the hard-working devs, of course - I guess my personal preferences are just changing. I'm not interested in spending tons of time messing with voltages and clock speeds and themes and kernels and APNs, etc. anymore.

Well a mean if you look at it from a different perspective "back in the day" yeah, what these devs claimed to be true, greater battery life, faster speeds, etc you did get and there was real improvement. Still we gotta understand back then stock android and phone makers weren't up to par and the phones weren't as powerful. Android was lacking in a lot of stuff and that's were modding grew.
But I don't need to give a history lesson, anyone who's been here for a while know why and how this all came about.
My point is though that android has caught up to the need for modding. Generally speaking (barring a persons provider) you get everything and in some cases more than you need without the need to mod.
Also some of the mods are also now available without being rooted, although not at a fast pace, but still on the rise.
I personally wouldn't coin it exactly as being "tied of flashing" but more so as some of you have mentioned the need is no longer there.
You can debloat your phone without root (I forgot the app/method), you get great battery life worth stock and of you even want to go further you have apps like greenify and my personal fav juice defender that can be used without root and so many other things.
There's other factors too that does make a difference like update cycle and harder issues and more phones etc that also leads people to the point of just sticking to stock but there are the petiole here that just like to tinker no matter what skill level you're at.
One last thing I would put out there is that us who are users of these mods wouldn't it be different if you were the ones creating them?

First and foremost the phone should perform basic phone functions flawlessly without significant lag such as making a phone call, sending text messages and web surfing. Could add GPS mapping to that list as it seems germane and pervasive.
Part of ROM fatigue is just the lack of this or perhaps the eternal search for it. Perhaps kit kat changes this.

My personal opinion is that any notion of "lag" in Android ceased to be a relevant discussion at least a year ago. Yes, you might still get the odd animation stutter here and there, but it's nothing that affects the actual usability of the phone.
As far as overclocking goes, 4 CPU cores at 1.9GHz seems pretty sufficient to me, but I understand that there will always be those who like to push their phones. I just feel like the difference is only noticeable in benchmark scores.

I sort this as well as my previous view. The current versions of android has caught up to everything modding was mainly used for. There isn't lag anymore, you get great battery, you also have a couple theme customization as well too. The point is there's a slow in the upward trend to mod.

I usually dont post these kinds of threads, so this one is an extreme rarity.
How many of you all are as relieved as i am that Kitkat is deadlock free? How many of you that ran jss/jls builds are relieved that they havent had a deadlock since trying out one of the Kitkat builds? And especially, how many of you are happy that the jwr vs jss/jls confusion is finally over. i am! im overjoyed that we have finally past this moment of suffing and confusion

and still deadlock free with a jss kernel on kitkat, yeah, that's cool
and yes single release > multiple
i'll be happy when kitkat comes out officially so we can get some custom stuff going. The Nexus 5 port is good for now. Also never heard of JLS builds. Just jwr/jss.
Isn't there a chance google could still release another build since nothing has been officially OTA yet. So not free from jss/jwr stuff yet?

It occurs sometimes when you type in an app (like Whatsapp, for instance).
The Keyboard and in fact the entire system locks up and you can't do anything about it.
Most of the time the screen still registers your inputs (which you can verify by activating the vibrate feedback) but the system doesn't react.
Sometimes these lockups only last a few seconds, sometimes the entire phone locks up completely so you have to restart it, though that is rare (at least for me it didn't happen yet).

its something that every user of a jss/jls rom experienced. some much more than others, but everyone experienced. while typing, the keyboard and everything else would lockup, for 10-30 seconds, then continue like nothing happened. for many, it would also happen in random times, and in random app. for some people, it happened constantly, for others it was a once in a while occurence.
I am totally relieved with KITKAT coming as a HERO and kicking out the a$$ of JWR/JSS kernel,ROMs..
Imagine, No wait why imagine - Now threads will be question free which version is this JWR/JSS? Which kernel should flash?
All the developer/OPs will be happy, relieved that they have no need to mention in the thread about this JWR/JSS sh*t.
All good,All KITKATTY..

Actually it's hearsay, since it's coming from Simms22 though, I take it as fact.

only thing is wifi wont work. but i dont use wifi at all
I am happy too, I never wanted to use any JSS rom because of deadlocks. Now it's time for my N4 to try CM for the first time (when it's out lol).
well @simms22 I am having really big lag in kit kat...
Maybe a hybrid jellykat is comming... :good:

lag, really? try trinity with it if losing wifi isnt a big deal. or, you can try ART hidden in the developer settings. its kinda like the custom dalviks that we were using in 4.3, only built in. it speeds things up. you will need odexed gapps for it to work though, or you wont boot. heres pa gapps odexed https://db.tt/EJ59aseZ

So is it definitively true that 4.3 kernels work with 4.4? I need wifi, cause my data plan is not the biggest one so I think I will wait to custom kernels (which will be now very more useful than in 4.3). It's a pity, since 4.4 is more battery efficient for me.
I think this low RAM consumption and better battery life is due to the accomodation of 4.4 to devices with lower specs than nexus 4 so developers will have to re-manage RAM to adapt it to our original neccessities...

well, all the 4.4 roms are still using the 4.3 binaries. so they arent true 4.4 roms, but hybrids. 4.3 kernels might not work with the 4.4 binaries. plus im sure that there are lots of other goodies that we are missing out on at the moment.
It was always beyond me why anyone ran buggy jss roms when there was perfectly fine jwr releases. I've never even seen a deadlock.

What's the big deal about 4.4 anyway

So now that I finally got it working, it just looks like they changed some interface elements. Which I personally don't think look as nice as in 4.3 (those rounded popups that notify you of, say, when a program is granted root, look awful, as do the icons in the pulldowns now; like they went in the direction of MS and tried to make things more monotone). Is there something I'm missing here? I mean I know on the back end a lot of APIs had changes and additions so I can see it being mandatory for certain programs, but beyond that....better battery? sleeker interface? even more buttery smooth? I mean the user experience....
i haven't received the update yet

I think it feels a bit smoother than 4.3 for me, I wasn't one of the people who had problems with 4.2.2. I think you're right about the interface changes though, they are subtle but in places they changed to the monotone look but left some of the blue holo stuff in there too like they couldn't make up there mind. Waiting to see how battery goes, certainly doesn't seem any worse so far.

Yep, its not going to magically last for weeks with 10+ hrs of screen time lol but it seems grand. Feel a bit underwhelmed after googles 'kitkat for everyone' talk and then we (n7 2012 users) don't have the ART option or the GEL launcher. I know you can install the apk, I actually use nova which now has the transparent top and bottom bars features but found it confusing after updating from 4.3 and seeing the same launcher!

At least the Alarm Clock and Google Now issues are fixed.
The stock 4.4 was really bad, graphics lag so much its not usable, I was coming from Purity Rom/Franco kernel. Now that I'm on AOSP 4.4 its much better, at least back to the same as Purity before, not noticeably better but at least not unusable like the stock one. Somewhat disappointing I guess.

You can find the new launcher in this thread
http://forum.xda-developers.com/showthread.php?p=47031599
It's called launcher 3. It's the launcher from the nexus 5 build of 4.4 without Google now and the keyboard popup when you press home. If you want the one with Google now you can extract it from gapps(I extracted it from PA odexed).

Me personally, am unimpressed. Seems that Google is starting to follow Apple's upgrade methodology... Make people wait a year, put out a "new" OS that just has some updated icons, leave out features on all but the latest devices to get people to upgrade their hardware and call it a day.
Fail.

I'm running rooted stock 4.4. I have no problem with "graphics lag" or any other issues.

New user here. I thought it was just me. Games are so laggy it's terrible. What ROM and kernel should I user to fix this!? Thanks on advance.

And it is people like you who don't have the slightest clue. Google doesn't make money from selling nexus devices.

it's supposed to have better memory management and smoother amongst other things, I've yet to install it as I really like SlimROM 4.3
I like the cloud printing. Its nice to be able to print stuff straight off my phone or tablet and have it sitting on the printer when i get home.
I'm running stock rooted. Only lag I notice is when pressing home to exit the app drawer. Scrolling is smooth, etc.

My thread (in my signature) has both APKs you need to install to get the full launcher - with Gooogle Now and everything. The keyboard bug has also been fixed.

It feels laggy compared to my Lumia :/
Default pdf and doc viewer disappear from 4.4

Soo... I switched back to Dvalik after using ART for a while.....

Wow the difference is noticeable! Both stock rom with franco's kernel. Dvalik patch on Dvalik runtime also...
Dvalik is sooo much more jumpy and less smooth flowing. I don't think i could go back to Dvalik again! Couldn't believe how much i noticed the difference!

Did you try the dalvik bionic optimisations from moto x?
Makes a lot of difference
I'll probably switch to art at somepoint once its less experimental. Compatability is an issue for me

I resisted the change to ART after using dalvik + bionic optimizations but the difference is really noticeable. I use an app called WeChat which is notorious for it's lag when scrolling through a portion of it called "moments". With ART it's almost buttery smooth were dalvik with optimizations is just downright laggy. That's just one of many examples for me. I do understand about the compatibility part, thankfully none of the apps I use has that issue.
Please continue discussion in one of the 2 existing threads
Who is using ART instead of Dalvik VM?
