Odexing Question

So i think most of us know what odexing is, it saves us a LOT of spave (40-50mb) on our ROM's and in some case makes them run faster
The drawback of odexing ROM's is that this renders them no longer skinnable/themeable
This script will odex a ROM: http://android.modaco.com/content/htc-hero-hero-modaco-com/301910/odex-script-for-unodexd-roms/
What i was wondering is, that if you flash a deodexed rom which is completely skinnable, and flash a theme such as expresso bar, if you THEN odex the system would that work?
So to summarize, if you theme your system BEFOREHAND, can you then odex the system?
Thanks in advance, sorry if i'm completely wrong here

I don't see why not, we just need a Guinea Pig to try it

Can you ODEX a single APK? I've got a ROM which is ODEX'd but adding non-odex'd files to it takes up a bit more space...
Also, what do you use to run the script?

Yeah you can odex a single APK, i've seen many threads about this, some people have even made this into a one-step process, almost like signing apps on a mac is now a one-step thing
I haven't run the script yet although i will as i like to customize my roms before flashing and these APKs are not odexed, i am running djdroid odexed, apart from some custom apps i flash with it and the expresso bar, i'll run the script and see if it'll odex the expresso bar and apps with it
I also see that the odexing package up in my first link also includes a zipaligning utility which is mighty useful
- Download and extract this zip http://www.romraid.com/paul/modaco-odex-1.1.zip
- Push the odex directory you just extracted to the device with 'adb push odex /data/odex/'
- Run the odex script with 'adb shell /data/odex/odex.sh'
The device will reboot (and take a little while to boot as it rebuilds the dalvik-cache).
EDIT: if anyone is interested i might odex my current rom (djdroid already odexed but flashed about 10 deodexed APKs and expresso bar) and i can test the memory and linpack performance before and after
NOTE: the process should also zipalign the APKs
If it fails then i've already backed up and we all learn something

Ok am currently doing the odexing process on an already odexed djdroid ROM.
I have installed about 15 apps which are not odex'd to internal memory and have flashed the expresso bar.
Current available space: 94.52mb
Current linkpack score: 40.099
Available space after odex: 97.23
New linpack score after odex: 41.29
HOWEVER: it seems that all the apps i customly flashed into the ROM have disappeared which is not good, all apps installed via market however are functioning great. Themes applied beforehand also working perfectly. Then again I odexed an already odexed ROM so perhaps this is why.
To summarize, apps via market work GOOD, themes applied before odex work GOOD, apps flashed into the system (estrong, mybackupro) seem to have disappeared which is NOT GOOD, however this was done on an ALREADY ODEXED ROM. If this were to be done on a deodexed ROM i can imagine this freeing a LOT of space and perhaps there wouldn't be the one problem stated above WOULD RECOMMEND
Hope this helps anyone

I'm trying to odex my rom but I get this for all apk's:
--- BEGIN '/system/app/Vending.apk' (bootstrap=0) ---
--- would reduce privs here
--- waiting for verify+opt, pid=2490
--- END '/system/app/Vending.apk' --- status=0xff00, process failed
And the result is a empty odex file (0 bytes).
Any idea what's happening here?
Thanks.
BR.

Any method (script) to odex a rom before flashing?

Interesting. I might try this. I am assuming my rom is deodexed as each .apk has a .dex file within it.
If I do it I will post some results and comparisons. I'm not planning any theme or font changes so this might be a good option for me!

Can anybody post somewhere this script? (link looks dead).
Thanks in advance.

Make themes for kitchen

I have trying to get themes to run in the Doc and Stefunel kitchen.
This is a pretty demanding task. Many (almost all) themes can not be used as is due to a non standard resources.arsc and 9.png errors.
There is some theme pro's here.
We like to find a some kind of way to enable any theme inserted in a rom.
Any ideas to make this in a easy way?
/Doc

No one here any ideas? I already proposed someone make a theme kitchen and integrate it with Doc's rom kitchen but apparently all the smart guys that got time and would know how to do that bought a Desire.
Which takes us back at doc's original question someone knows a fail-proof way to integrate themes into roms without having to flash a post-install zip?

Hi Doc,
i know this isnt way you want, but probably it can work:
What about make some script, witch will do:
1) after flashing ROM and start android - reboot android to recovery
2) (i dont know if it is possible) make script for CWM witch will automaticaly flash theme and reboot to system
If Im wrong .. ignore this

I've never need a post-install script to put a theme into a ROM.
Except for the JPY Gingerbread, but me and XGX got that hammered out in the thread in the Captivate forum and it works just fine without a second .zip.

Hi, any link to point in right direction is most welcome

I've merely dropped the framework-res.apk and twframework-res.apk into the /system/framework. And any other files like android.policy.jar that goes with it.
For JPY, I had to take a few extra steps:

[Q] deodexed vs odexed?

what is odexed and deodexed?

"Deodexed ROMs have their .apk's (which are basically the application packages) repackaged in a certain way. An "odex" can be thought of as a collection of parts of applications that have been pulled out and optimized before booting. This speeds up the boot process - in a way, it preloads part of the applications - but it also makes hacking those apps difficult because part of the original code is already extracted somewhere else.
Deodexing is just a process of putting those pieces back into the original applications. It takes a while to extract those parts and build the .dex cache (aka Dalvik cache), but only because the relevant parts aren't in an easy-to-access place for the system. The advantage of this is that an app can be modified effectively and the developer doesn't have to worry about conflicts from the separate odex part of the code.
So, short version: "Deodexed" ROMs have all their apps put back together. If an app can be themed, for example, a deodexed version of that app will not get messed up when the modified .apk tries to mesh with the odex of the original un-modified .apk. Because it's not there.
If you want an aftermarket theme, you need a deodexed ROM. I'm not sure if deodexing can be done to individual apps within a non-deodexed ROM."
Taken from PPC Geeks

You've probably seen a few odexed ROMs popping up... there will be more and it should be the way to go these days... simply put, odex is better for optimizing and speed, all while keeping sense functional. The stock ROM out the box is odexed. It is also the most stable.
Most ROMs out right now are deodexed for modding and theming purposes.
As of late It has been perceived that it was not possible or just too difficult to theme and mod an odexed ROM. I believe the developer Aamikam has come up with a way to not just use his optimizations and tweaks from his previous ROMs but also add custom mods and themes all while keeping the ROM odexed...
I may be wrong but most if not all of the newer themed odexed ROMs out are off of his base.

Thanks alot guys! Very helpful!

[APP] 'OdexMe' application

OdexMe is an application i've written for my MCR ROM, but that should work on any ROM with init.d support and busybox in /system/xbin.
Basically, it's an APK you push to /system/app and when you run it, it...
Reboots your device
Odexes everything in /system/app
Deletes the dalvik cache and it's own APK (as you only need to run it once)
Reboots the device and rebuilds the dalvik-cache
As you may or may not know, the dex files for the system applications take a fair old chunk of space on data - this gets around that.
Of course, odexed /system/data means you can't make any /system/framework changes, but how often do you need to do that? If you DO need to, you can reflash your ROM, do the changes, then run OdexMe again.
As I say, this is written for and tested on MCR, so if you try it, backup first and use at your own risk.
You can check it's worked by looking at /system/app after reboot, it should have a bunch of odex files, plus /data/dalvik-cache will have shrunk lots.
You can grab it in this post and one last thing - the initial reboot and odex takes a while, so be patient.
ROM devs - feel free to include this if you like it in your ROMs, but please let me know (and give me credit) so I can contact you when a new update comes out (i'm working on the next release with a few other tweaks).
Enjoy!

Thanks Paul..
You are very productive on XDA today.

thanks, always good to have that options..
NICE WORK!

Nice work Paul Thanks
PS Loving the your Custom ROM for the Gal s2

Hi Paul!
As usual you did a fantastic job!
I was wondering if your app also delete classes.dex inside APKs! As you already know this should be deleted as well!
Thanks in advance!
L.

Nice!
Works with Revolution 2.5 (KG6).
Now the Tw4Launcher from Fr4gg0r is also odext and gmail shows more than the last 3 mails on startup. THX
@Leomar
Yes it does delete the classes file inside the apk.

I'm not that known with odexed and deodexed stuff etc. but i'm wondering what's the advantage of odexing the system apps?

*Quicker initial bootups of custom ROMs
*Less memory is consumed
*Less storage used in /data due to the fact that pre-optimised dex files are stored on /system already (save space and boost performance)

Thanks Paul

Yes. It also then zipaligns the resulting APK too.

Thanks for explanation.. I'll stick with deodexed atm, enough memory free and space left in data and boot speeds i dont care about

Works fine on criskelo v12.
Thanks!

I´m Sorry, but i think (and I tested it) on my Milestone and the Bootlogo don´t move. So it stands on one Point and I have to go back into my OR..for sure i´ve made an nandroid Backup..do you think this is possible?
Milestone CM has the init.d folder and the BusyBox.. thank`s for your hard work !

i'll try it on my MIUI 1.8.12 rom today, but first a nandroid just in case

Paul this is the sort of thing I know you are really good at doing, but you don't release enough useful apps like this.
You should start releasing more apps like this that are useful to the dev community as a whole.
Good job.

I keep meaning to pack all these sorts of things up into a 'super-app' but never get the time.

Hi Paul,
Massive thanks for the application, I deodexed KG6 and edited some system files to create a ROM with just the features I really wanted.
Now odexed successfully with your application.
Just a quick question, would it be possible to odex /framework later down the line too? I'm assuming the framework would need to be odexed first before /system/app?
Thanks again, great to see you on the SGSII scene after I was a subscriber to Modaco for your work on the Desire.

I used this app moment I noticed in MCR rom and then odexed cog and ASOP Rom. All is well except I couldn't see any of the ringtones in either of these two roms.
I will give it another go and report back.
Thanks for a great app.
Confirmed; not only ringtones but also music player can't see any song too. checked with drm services, these are running fine.

[Q] Odex or Deodex?

I am a little confused about the odex and deodex terminology. I am looking at various mods or hacks and I'm afraid I could mess something up because I don't know if I am deodexed or not.
I am on the stock ROM, I flashed chris41's stock kernel repacked with CWM and I rooted by installing zip of su and bb from the market. That is all I have done so far.
With that being said, am I deodexed or odexed?
Thanks in advance
P.S. I did search for the answer but did not find one.

Stolen from matlock and akazabam, rooting guide for dummies
Odexed - 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 applications difficult because a part of the coding has already been extracted to another location before execution.
DeOdexed - 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 the worry 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."
this is an excerpt from the rooting guide for dummies. thanx to matlock and akazabam. its their words and not mine.
I think most stock roms are odexed...

Thanks for the info, that helps me not make a big mistake installing the hotspot hack and AIO mod.
