[MOD][DEV][HOW-TO] Enable Android Runtime (ART)

Hero · Dec 1, 2013

Here it is guys, the how-to for enabling ART on the new 4.04.1540.2 (Android 4.4) base! I have tested whether ART works and sadly, I get bootloops when using it (both ART and ART (debug). ART (debug) seems to not stick since the phone does boot up, but the selection still shows as "Dalvik" not "ART (debug)". I only tested this on my deodexed ROM so I have no idea if it will work on ODEXED. Hopefully we can get more devs collaborating to get this working. Anyway, enabling ART in the Developer Preferences is really easy.

PART 1

Decompile Settings.apk
Navigate to smali.com.android.settings
Open up DevelopmentSettings.smali in Notepad++ or a text editor of your choice

Locate the followiing code (onCreate() method) and delete the part in RED

Code:

    const-string v3, "show_touches"

    invoke-direct {p0, v3}, Lcom/android/settings/DevelopmentSettings;->findAndInitCheckboxPref(Ljava/lang/String;)Lcom/htc/preference/HtcCheckBoxPreference;

    move-result-object v3

    iput-object v3, p0, Lcom/android/settings/DevelopmentSettings;->mShowTouches:Lcom/htc/preference/HtcCheckBoxPreference;

    const-string v3, "wifi_display_certification"

    invoke-direct {p0, v3}, Lcom/android/settings/DevelopmentSettings;->findAndInitCheckboxPref(Ljava/lang/String;)Lcom/htc/preference/HtcCheckBoxPreference;

    move-result-object v3

    iput-object v3, p0, Lcom/android/settings/DevelopmentSettings;->mWifiDisplayCertification:Lcom/htc/preference/HtcCheckBoxPreference;

    const-string v3, "select_runtime"

    invoke-virtual {p0, v3}, Lcom/htc/preference/HtcPreferenceFragment;->findPreference(Ljava/lang/CharSequence;)Lcom/htc/preference/HtcPreference;

    move-result-object v2

   [COLOR="red"] if-eqz v2, :cond_5

    iget-object v3, p0, Lcom/android/settings/DevelopmentSettings;->mAllPrefs:Ljava/util/ArrayList;

    invoke-virtual {v3, v2}, Ljava/util/ArrayList;->add(Ljava/lang/Object;)Z

    invoke-direct {p0, v2}, Lcom/android/settings/DevelopmentSettings;->removePreferenceForProduction(Lcom/htc/preference/HtcPreference;)Z

    move-result v3

    if-nez v3, :cond_5

    invoke-virtual {p0, v2}, Lcom/android/settings/DevelopmentSettings;->filterRuntimeOptions(Lcom/htc/preference/HtcPreference;)V[/COLOR]

    :cond_5
    const-string v3, "hdcp_checking"

Recompile Settings.apk and push it to your device!

In case you don't know how to enable Developer Preferences in Settings, go to Settings -> About -> Software Information -> More. Once at the "More" screen, tap the Build Number option seven (7) times.

Here are some screenshots

I did it yesterday and it just stuck at boot animation(animation is complete). I am on stock odexed system.

Dunc001 · Dec 1, 2013

As far as I know from running 4.4 ROMs on my Nexus 7 you can only use ART on a fully odexed ROM, deodex will always result in failure to boot. Also some apps are not compatible with ART yet so you may well find a few specific app FCs. It may be that sense apps don't play well with ART yet. Remember it is still a developer only option and not mainstream yet so not really too much of a surprise...

yes tried on 3 different roms both odexed and deodexed not working on both. i think we need some core files for art to work which htc didn't put in as art is still in testing mode

libart.so ...

So pretty much none of the options work (besides dalvik, of course)?

tried it myself at first after setting from shell, and secondly after @jerrylzy gave me his classes dex and pointed out the obvious

anyway in both cases bootloop . on odexed and deodexed as well . logcat doesn't tell me too much yet. still poking. i know for sure that if you have xposed installed ART won't stick after reboot

Try pushing libart.so from a current CM11 HTC One build, set permissions, reboot, enable ART. Not running 4.4 on my One atm so can't test.

Is ART working on CM11?

I was running ART on a GPE rom fine.. Honestly didnt feel as fast as I thought it would.. I'm back on a Sense rom now and it would be awesome to see this working..

CM11, GPE, whatever - just so long as you grab a binary that's confirmed working on HTC One already regardless of the build. Several of the current 4.4 non-sense ROMs in the two forums already state working ART. Just experiment.

There is an easier way
Xperia, HTC, samsung, LG stock roms don't ship with ART option in developer settings, so there is a workaround Enable ART runtime on any Stock ROM via recovery

How to Enable ART on any Stock or AOSP ROM

Simplest way to enable ART on an AOSP ROM is through “Developer options > select runtime”. But sadly, the option is not even available in most stock ROMs may it be HTC, Samsung, Sony, LG, Motorola etc. The work around is following the steps mentioned below:

Pre-requisites:
1. Rooted 4.4.x ROM (Stock or Custom) with some custom recovery (CWM or TWRP)
2. Xposed framework is not compatible with ART runtime. You must uninstall Xposed framework before continuing.
3. To Check If You Are Using ART Or Dalvik, goto
Open data/property/persist.sys.dalvik.vm.lib in Text Editor, if it shows ‘libart.so’, you’re already on ART, else it would say ‘libdvm.so’.
4. Full list of apps that don’t work with ART.
Note: If libart.so and libart-compiler.so is Not Present in lib folder. Your ROM Doesn’t Support ART.

Step 1. Download Enable ART, Enable Dalvik flashable Zips from xda thread= http://xdaforums.com/showthread.php?t=2707841 .

Step 2. Flash the Enable ART zip in recovery and clear Dalvik cache.

Reboot, *your ROM would boot and create ART cache for the first boot.

Troubleshooting: If you’ve any bootloops or problems, you can revert the change at anytime by flashing enable dalvik zip.

This is just cut and paste from the article linked to in above post

Good Luck

Also, does anyone know what the base 4.04.1540.2 that hero mentioned in the op is? Seems like an US Dev base bc of numbering but I haven't heard of this yet.

I was running ART on my nexus4 and Xperia z1 with CM deodexed, so i dont think that's the problem
