[Explained] ART Runtime in Android 4.4(kitkat) - Android General

What is ART?
ART stands for Android runtime which is a new runtime like Dalvik which is introduced experimentally in the 4.4 release. This is a preview of work in progress in KitKat that can be turned on in Settings > developer option.n 4.4 both runtimes are now available, Dalvik runtime (libdvm.so) and the ART (libart.so).The user can choose it from developer options.

Difference between Dalvik and ART
Dalvik
Dalvik runtime uses JIT(Just-In-Time) compilation to interpret Bytecode
Now lets understand the technical info and terms in the above sentence.

Compiler
A compiler is a program or set of programs that transforms source code written in a programming language (the source language) into another computer language

Bytecode
Bytecode also known as p-code (portable code), is a form of instruction set designed for efficient execution by a software interpreter

Interpreter
Interpreter is a program which translates the source code into computer/machine language

JIT compliation
JIT compliation interprets the bytecode into machine language at it's runtime (at the time when the apps are executed).

Click to collapse
Now summing up all these Dalvik runtime does everything when the apps are executed. Now this is where we must discuss odexed and deodexed ROM. usually all stock ROMs released by OEMs are only odexed only due to this reason. odex means a part of the app is already compiled and it is written into dalvik VM(VM=Virtual Machine). and it runs at boot so while execution of apps JIT has to compile only the remaining part of the code when the apps is executed, this is why odexed ROM is faster than deodexed ROM.
But the disadvantage of odexed ROM is it cannot be edited/themed easily as a part of code is seperated in a separate file, and deodexing means the odex part of the file is put back into the apk/jar itself which makes editing/theming easy since the full code is packed inside a single file but it decreases speed because JIT has to compile full code when the app is executed
ART
ART uses AOT compilation to interpret bytecode.
I hope you can refer to dalvik paragraph to know about these technical terms.
Click to expand...
Click to collapse
what is AOT compilation
AOT is a method of compilation which compiles the code into machine language when the app is installed itself, means no compilation is done at the time of execution of app. This makes the apps launch speed amazingly fast.
Click to expand...
Click to collapse
Advantages of ART over Dalvik
The apps launch speed is amazingly fast in case of ART since nothing is compiled at execution.
Boot speed is faster than dalvik since nothing is execued from dalvik partition as in case of odexed ROM in dalvik
Increases battery backup by reducing CPU work due to absence of compilation work on apps execution.
And finally it is a great reward to developers because most of developers are worried that odexed ROMs are faster than deodexed ROMs but they will deodex their ROMs since they heavily theme it. In case of ART whether the ROM is odexed or deodexed it doesn't matter, it compiles the full code into machine language on installation of apps. so even deodexed ROMs are as fast as odexed in ART
Click to expand...
Click to collapse
Some disadvantages of ART
Since ART precompiles apps on installation, it takes 10-20% more space upon installation than dalvik. But this can be simply solved by using apps like apps2sd/link2sd/gl2sd when your apps storage partition is full
One more is since it is only experimental feature now some apps are incompatible in ART which will be made compatible soon on their updates.

Here is the list of apps which are compatible and incompatible in ART.

Finally ART is one of the best feature that google brought up in android 4.4 (kitkat)

I was wondering what was the difference between Dalvik and ART terms, but you made things pretty clear in this post. Thanks a lot

Thank you for this. Makes it a little easier to understand.

Explained me a lot, thanks!

Interesting information. Thank u very much for spend part of your time to write this

Thanks for that explanation, has made the whole thing clearer to me now

Thanks bRO. Very nice

[FX-MOD][SENSE] Reboot option in power menu 4-in-1 (UPD)

this is an updated* version of my framework mod that adds reboot (normal, hboot, recovery) option to the power-button menu on htc sense based desire roms
*: a new option ('hot restart') has been added that will allow you to respawn android's system server process, thereby starting with a "clean system" w/o actually rebooting the device (credits to xda member appelflap for the idea, you can have a look at his app 'hot reboot' here. i took a slightly different approach to killing the process but the basics remain the same)
enjoy
requirements:
htc sense based desire (froyo) rom (HD VERSION HERE)
deodexed framework libs
busybox with pkill support (or any other pkill implementation, accessible in $path)
how to install:
please make sure your device/setup meets the requirements above
check your framework build number (settings >> about phone >> software information >> build number)
download the archive that matches your build number
copy it to your sdcard and flash it in recovery mode (as always, it is advisable to do a nandroid backup prior flashing)
impact:
a framework lib (/system/framework/android.policy.jar) will be overwritten
the first boot after flashing this may take a (long) while (dexopt will be busy)

source code, porting to other htc devices:
due to the nature of the hack (patching a htc-modified, closed source framework lib) there is no "source code" for it
obviously, i also can't provide a smali patch applicable for any framework version / htc device
for reference, i've attached the smali patch for my own device/setup
it doesn't take a great deal to understand it, porting should be relatively straightforward. you should also take into account that string/icon resource ids may vary between different framework versions, and that some versions don't support com.android.internal.app.ShutdownThread.reboot()

Works on my Desire with LeeDrOiD V2.1a with Base HTC RUU 2.10.405.2.
But: after every hot reboot the function keys remain lit after the first power off (automatic or manual). After the 2nd, 3rd etc. power off not anymore. Very odd.
it works great man...thanks!!! i added it to my rom if you want to remove it please tell me
Thanks, great work! I just want to mention it the boot after flashing took a long time here, like 4 minutes which is strange.

Ok, thanks. Just to make sure - not whole deodexed is required, just android.policy.odex, right? Is it possible to edit this jar file and change the language of "Normal" etc... and here footprint is also required as in 3in1?

odexed vs deodexed

What is ODEX and DEODEX?
In Android file system, applications come in packages with the extension .apk. These application packages, or APKs contain certain .odex files whose supposed function is to save space. These odex files are actually collections of parts of an application that are optimized before booting. Doing so speeds up the boot process, as it preloads part of an application. On the other hand, it also makes hacking those applicationsdifficult because a part of the coding has already been extracted to another location before execution.
THEN COMES DEODEX
Deodexing is basically repackaging of these APKs in a certain way, such that they are reassembled into classes.dex files. By doing that, all pieces of an application package are put together back in one place, thus eliminating theworry of a modified APK conflicting with some separate odexed parts.
In summary, Deodexed ROMs (or APKs) have all their application packages put back together in one place, allowing for easy modification such as theming. Since no pieces of code are coming from any external location, custom ROMs or APKs are always deodexed to ensure integrity. So:
Odex = +speed -customization
Deodex = -speed +customization
I think that you like more speed and less customization (less costumization for dev because is to difficult mod an odex file)
So that's why I just odex my Google edition rom with this and you can read the whole thread.
http://forum.xda-developers.com/showthread.php?t=2390162
Note, it's wise to odex just your system apps. Not data but that's up to you.
I was always under the impression that deodexed apks are only slower on first boot/run. After that, everything is loaded into cache and deodexed is the same speed.
Is that incorrect?

Most of the sources I googled about odex and deodexed came up with this explanation. So we could probably assume that it's correct. I've run a couple of odexed roms on my Gnex and most recently, the S4. My personal opinion? I really see no difference at all in terms of UI, there's probably a difference when it comes to loading apps but if there is I hardly notice it at all.
In addition most deodexed roms are zipaligned and the result being the apps consuming less ram. More ram = more cached apps, cached apps = faster loading of apps.
Again this is all just my opinion.

Samsung always releases a firmware ODEX based.
Basically ODEX is always faster, but as the S4 is really quick anyway you will not notice if you are running a deodexed firmware/rom i.m.h.o.
Another personal opinion is that all mods can be converted to odex again, just look at the released framework of JKAY. Heavy mods on that and still he releases a deodexed and odexed based version.
If the maker of a mod cannot provide you with a odexed version then maybe he is not that good..... (no bashing intended)

[ROM] [Android 4.4 Kitkat] Unofficial Shiny ROM for Grouper with Built in Gapps

[TYPE][ANDROID VERSION][NAME][OTHER INFO][DATE]
This ROM is a fully AOSP build of Android 4.4 KitKat. The source was downloaded and compiled by me.
It is exactly what Google will release in “a few weeks” for the 2012 Nexus 7 when they release KitKat
This ROM is based off of Baldwinguy77's work on 'Shiny' for Toro, and uses his vendor. I did all the bring up for Grouper(with a ton of help from Baldwinguy77) The difference is that some of the changes he has made to the system aren't here, this is AOSP with a few modifications to make it run, Hence the Unofficial Tag.
There will be changes coming to fix bugs and remove redundancies between AOSP and Google Proprietary files. Also, changes will be made to the system to include some other small features in time. This ROM will branch out from baldwinguy's initial work to something a little bit different.
Google Apps are included in this build.
Bugs:
Boot Animation
You tell me
I, nor Baldwinguy77 is responsible for anything that goes wrong during the installation.
Special Thanks goes to Baldwinguy77 for helping me out and supplying his vendor files, as well as answering all my questions in the past 72 hours. Please consider donating to him as most of the initial bringup was his work: Paypal Donate Link for Baldwinguy77
Also, please note that this does not contain root. You are responsible for adding root at the moment.
Feel free to let me know if anything goes wrong. This is my first public posting of a ROM I have built from source.
Also note that the first boot is extraordinarily long.

Enjoy!
If you really like my work, and you haven't donated to baldwinguy77, consider donating to me: here on paypal

does camera work on this build?
popup keyboard and rotating fixed ??
otherwise it's the same as all the other 4.4 roms / ports outthere
Forget keyboard popup, are you fixed rotation and gradient glitch problem ?
Let him feel special for releasing this, after all he did all the work. Who cares if there are 3 other similar ROMs

I tested ROM, everything is same with other similar ROMS...
Can you please add this bugs to your thread:
-Rotation
-GPS
-Camera
-Launcher Keyboard Popup
I will add those. I have an idea on GPS and should have it working be end of day. The keyboard issue seems proprietary, but I have ideas about it.

Well, first, my understanding is that you should separate the GAPPS from the ROM, per Google's license... that being said, included or separate, can you deliver them ODEXED so we can try Art instead of Dalvik?

Please explain what you are talking about with regards to Art.
I include google apps for convenience, and several ROMs have done this same method. At the end of the day, I plan on providing what Google will eventually provide for the N7.
FWIW, the CM 11.0 source has dropped, and I've posted some quick stuff about it in the build thread.
My n7 is down for the moment (loose charger slot thing) but that doesn't mean y'all should have to wait
Good luck, we're all counting on you.
This ROM unrooted my N7 and is giving me constant acore.process issues. Think I'll go back to koko98's version, seems more stable.

ART is Google's runtime replacement for Dalvik - you can enable it under settings, but if you install 'normal' GAPPS, i.e., deodexed ones, it conflicts and they keep FC'ing
My understanding is that won't happen with odexed gapps; with them, we could try ART instead of dalvik.

Now that I understand and have researched it, I'm going to take this idea for right now:
I will not be distributing a seperate gapps package that is odexed. This ROM, anyways is deodexed out of the box and as such, probably breaks all compatibly with ART.
Android ships with dalvik, and for now, I will not be offering support for something which requires me to redo the rom and provides no benefit. In fact, it appears to break many apps on the app store right now.
If in time, ART is shown to be stable and has all the issues ironed out, I will begin odexed builds and provide odexed gapps.

I'm assuming you are talking about swapping positions of the two buttons. I'm sure there are other ways of doing this but that is one of the Many options that you have in GravityBox. You'll have to be rooted, have Xposed Framework installed and if I remember right an updated version of busybox installed.

You're absolutely right! I forgot about that! But... I'm not personally going to worry about a few milleseconds or 10ths of a second enough to give up using Xposed Framework. I think we can't lose sight of the fact that the performance we see now even when using dalvik instead of art is at this point in time substantially better than what it was not that long ago. Just my opinion of course!

Agreed! For the time being, some of us are split into two camps.
I thought the new optimized libraries brought Dalvik up to Art's speed.

I suspect that you are right again at least about the benchmarking. And it could absolutely be my imagination but some apps (not many) do seem faster in operation with the dalvik bionic patch and the one that comes to mind is Feedly. I could be wrong. Anyway.. having the choice to use either one is pretty nice.

Been using Xposed for a while now so I could just be remembering wrong! Maybe it depended on what modulus you were using. Busybox Free (Stericson) is in my opinion the best app for installing busybox if you ever need it, I use the pro version myself. Might want to make a backup if you start modifying system files, flashing kernels or roms.

If you want to spend the time swapping/comparing, use a common lag 'test' and see for yourself.
http://forum.xda-developers.com/showthread.php?p=47533904
I haven't tried the patched Dalvik myself since ART, but if it can do what ART does (not placebo), then it's another way to the same goal.
Apologies to OP, I certainly didn't mean to turn this into a Dalvik/ART thread...just that Xposed currently is Dalvik only, but that the dev wants it to be ART compliant in the future.
Oh and seconded on Stericson Busybox Free! Cheers!

@Vegastroy .... ART is the new Android Runtime which was first introduced with the release of the KitKat O/S, it replaces Dalvik Runtime. The main purpose of ART is to improve performance and smoothness of the core Android platform and battery life. You can enable/disable it by going to :::: Settings>Developer Options>Select Runtime ::::
There have been some posts in motor g forum that complain that using "Art" causes several games to F/C or not run at all. The full benefit of having "Art Runtime" will probably not be seen until a future release of Android O/S which has been optimized for Art and then there will be Apps which are also optimized for Art, so things will get better.
For now , whilst there is still a choice in Settings to use either Art or Dalvik, there is nothing to stop you swapping about
