ART Runtime for low memory devices! [Hot tips]

Those who are using CM11 or other custom rom with low internal memory can now use ART runtime!
Just add this line to build.prop- dalvik.vm.dexopt-data-only=1
Enable ART runtime from Developer option!
Reboot your device. :laugh:
Please make sure that you have 150 mb space in data partition.
Then dalvik-cache/art-cache will be saved in /data partition instead of /cache partition.
Please hit thanks button if it works for you!
In my old sgs I can use it via dev options and just choosing ART, but imho it makes the phone a bit laggy and some apps fc... It needs a lot of improvement thats for sure

Excited to start using ART, but so far I'll be sticking with Dalvik since WhatsApp does not work with ART yet. :crying:
I always wondered. How much better is ART compared to using Dalvik?
Sorry, but there is already an ART discussion thread in General: http://forum.xda-developers.com/showthread.php?t=2531342

[AROMA][ HOW-TO ][4.4+] [ Enable ART Or Dalvik From Recovery ]

I Made 2 Small Scripts Flashable Files Around 100Kb Each.
No Need To Change To Add Files Anythings
Just
Reboot To Recovery
To Enable ART Flash This : Mega Devhost
Wipe Dalvik Cache
To Revert To Dalvik Flash This : Mega Devhost
Wipe Dalvik/Cache
First Of All ART Is Not Compatible With Xposed. Xposed Itself Change ART To Dalvik. So If You Want To Use ART Uninstall Xposed.
To Check If You Are Using ART Or Dalvik
Goto
data/property/persist.sys.dalvik.vm.lib
Open File In Text Editor
If It Says libart.so means You Are On ART
if It Says libdvm.so Means You Are On Dalvik.
If libart.so and libart-compiler.so is Not Present in lib folder. Your ROM Doesnot Support ART.
For Those Who Are Getting Update Binary Error An Aroma Package Is Made By @Patrics83
Features :
* It Doesn't Use Update Binary : So No More Update Binary Issue
* It Will Show Which Run Time You Are Using.

It will work on the note 3 n900?
Because by default there's no option at the developer option to select the runtime environment
Seems like Samsung disabled them
So my question this flashable zip will work?

Might work. Worked on my LG G2.
husen4u, thank you for very interesting method to switch between ART and Dalvik!
Will your scripts wipe Dalvik cache automatically in the next version? It would allow user NOT to wipe Dalvik cache manually.
@husen4u: but is correct first zip to enable art? i see all two script report "Enabling Dalvik...", so i excract both updater-scripts and i compared them both and they are identical

@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

xposed is not compatible with ART.
With xperience kernel v.18, you need to install "Wake Gestures" module in Xposed. Then you can activate d2tw from the module.
Hope it helps.

I asked if dalvik with xposed was better than art ( excluding xposed as it isn't compatible! I know that :3 ) ... And that kernel isn't showing up on trickster mod...

Oh sorry if I misunderstood your question
I prefer dalvik with xposed. Because ART for now as they say is "experimental". From what I read, it's like a hit or miss thing. Some apps load faster with ART, some load slower than dalvik. And If you are using xposed modules, you're stock with dalvik anyway.
With the Xperience kernel, I have no idea. Because I am using fauxclock. And never encounter that issue with tricksterMod last time I used it. You can maybe try to do uninstall/install, clear cache and dalvik, reflash kernel. I'm no expert, so hopefully someone can help you futher.

Did you purchase fauxclock ?
Sent from my Moto G using XDA Free mobile app
Yes. I guess it's a good purchase if you want additional options. Specially if you use faux kernels. But the free trickersmod has sufficient options. [emoji4]
