What's Deodex and Odex?

I've been seeing those words a LOT in recent threads.
Any detailed explanation on them please?

De-odex: Apk files have respective odexes that devs use to supposedly save space. Deodexing means you convert it back to a .dex file and put it back inside the apk. This allows you to easily replace files (not having to worry about odexes), but the main point was to deodex services.jar so that you can change all text to different colors (such as the clock color to white) and to deodex services.jar, you need to deodex everything.

Thanks. Are themes available in Deodex or Odex? Sorry for noob questions.

Related question also....
- Which can live with which? (Deodexed ROM + Odexed Theme? or Odexed ROM + Deodexed Theme?)
You know, like type O is universal donor and type AB is universal recipient...do these work similar or only deodexed with deodexed...?
(where is that darn wiki??)

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.
I think that's the general idea, anyway.

You will never find an odexed theme since the odex file would contain things that needed to be changed, thus themes are deodexed. Themes basically just replace the .apk or .jar with their version, which wouldn't work on an odexed rom.

Basically, Android uses a a java based virtual machine as the bases for running programs. This virtual machine is called Dalvik. A .dex file contains the cache used by the Dalvik VM (called Dalvik-cache) for a program and is stored inside the .apk. A .odex file is an optimized version of the .dex file which gets stored next to the .apk as opposed to inside the .apk. This process is done by default to system apps. Deodexing is the process of converting the .odex files back into .dex to be stored inside the .apk so that things can be more easily modified. So a deodexed rom is one that has been through the deodexing process. Deodex can just as easily be called Unodex or any other pre-fix you wish to use.
Hopefully that cleared that up.
EDIT: Darn, beaten.

Thank you all. So...themes are deodexed. And only run on deodexed rom...got it. Meaning...I need a deodexed version of the new Froyo to keep my white Rosie. Cool.

Yeah, but you clearly know it better than I do.

if you install a de-odexed rom, will the system automatically rebuild the Dalvik cache and appropriately odex the apk's, or is this something that a dev needs to do manually beforehand? In other words, are there any disadvantages to a de-odexed rom other than an initially slower phone? will the phone eventually rebuild the cache and perform as an odexed system would?

^bump^
Same question as vinconti - will a deodexed ROM run slower than an odexed one?
Thanks

<InigoMontoya>You keep using that word. I do not think it means what you think it means.</InigoMontoya>
Thanks for the explanations, all. I just rooted my D2 but haven't done any themes yet. This helps, but only from the standpoint of I'll have to get back into flashing. I thought I left that behind when I trashed my Omnia.

I have a regular odexed ROM. I replace some of the apk+odex files by deodexed APK's, so that seems to be no problem. But I was wondering whether this would also work for jar+odex files (e.g. android.policy.jar)....

If this does actually work without problems does that mean we'd only have to de-odex certain .apks rather than the whole ROM?

This is pretty much my question as well. This whole Odex/Deodex thing is totally frying my brain.
I'm not trying to do anything fancy, I just want to use the WiFi tether feature. Which one is good enough for just doing THAT?

I can confirm that the ICS theme from Overstew overrides the ICS transitions. This is what I did (Im a noob so this is the first time using apk manager) Before i started, my phone was running Calk's EL26 Custom rom with Overstew's theme. First I tried to decompile framework from current setup (Found out you can't decompile themed framework). I ended up extracting framework-res that came with the rom i flashed. Made edits noted in link above and pasted apk using root explorer. Phone soft booted and ICS transitions work but noticed some things weren't themed anymore (Battery and power options were main ones noticed) I rebooted into recovery and wiped cache and dalvik and flashed ICS theme again. Phone loaded and ICS transitions were gone (Which makes sense since I'm replacing the edited framework apk). Hopefully Overstew adds this into his theme.
*UPDATE* I never done this but I will see if i can extract all files from current framework (With ICS theme applied) to decompiled framework in projects folder. Will see if this works.

These are the steps I did...
I pulled the Framework from the ICS 2.1 Theme & decompile it using ApkTool (I could never get Apk Manager to work properly). Afterwards I did the necessary edits to the framework & then flashed the new framework onto my device. If you want I will post the framework with the ICS transitions baked in.

[ICS][MOD][CWMR]Long Press volume changes music track

So after desperatley wanting this mod to work on my captivate glide at any cost, i went after it myself. It looked easy at first but turned out to consume a lot of hours figuring out how to compile decompile and understand basics of smali.
What it does ?
As in the title, pressing the volume buttons a little longer (400 ms) will make the stock music player skip to next track (up vol) or previous track (down vol). This only works while the screen is off and phone locked which is basically the purpose . Right now will work on deodexed ROMs only, meaning pepole having "android.policy.odex" file in the system/framewrok folder would not be able to use this mod.
Caution : The mod if goes wrong can/will make your phone stuck at the boot animation unless the mod is removed. Copy both the files so you can restore your original file back in case it doesn't work for you.
How to Install
1) Make sure you are rooted. and boot into CWMR.
2) Flash LongPressVol.zip - Installs the mod and takes backup
3) Wipe Dalvik and Cache partition
4) Reboot and "Upgrading android" screen should show up.
You are done and now test it and let me know if it works for you. Enjoy!!!
Restore original/Remove Mod :
1) Boot into CWMR.
2) Flash LongPressVolRemove.zip - Restores your original android.policy.jar file
3) Wipe Dalvik and Cache partition
4) Reboot
Tested to be working fine on following ROMs
Nardholio's NardROM 0.4
Thegreatergood's LiteROM .4
Credits : Ported with help from the guide posted by jakubklos -> http://forum.xda-developers.com/showthread.php?t=1770564
Next update :
CWM flashable zip (will need some time to learn how to do that - Done
Post the Diff and the code to make it easier for other roms to include it if the android.policy.jar changes. - In progress

Awesome, been missing this mod since leaving my DHD
CWM Flashables worked great..... But since I'm using the stock rom which has not been deoxed it did not work.
It booted though didn't notice any adverse affects
Not to put you on the spot but do you think you could use the UCLH2 .jar and make a version that will use odex. not sure if anything would have to be done to the odex file but I have included the non odexed android.policy.jar files if you wouldn't mind taking a stab at it. If you could just modify the .jar file I'll test it. I would be forever in your debt!

Force closes PowerAMP and Nova Launcher.
Tested on ICS Leak.

Just delete the odex file and clear cache and you should be fine. You don't have to deodex the whole ROM.
or for extra points you can reodex, which theoretically will boost speeds a bit (although I'm experiencing wonderful speeds on my ROM). Redodexing is pretty easy (just Google it) and doesn't require him to do his mod again.

Cool thanks for the tip!

Tried with no success stuck at boot screen. Thanks for the hint I'll try re odexing it and see if that will work next.
I like all the bloat that the stock has except the att apps, I would love to try your ROM but I would prefer a completely stock version of it with little modification and fixes. I have tried to do it myself with no success and simple don't have the patience for it. As my computer would end up at the muzzle end of a AR15. I really don't want to waste ammo or buy a new computer just yet. LOL ^o^
I'm very happy with the stock rom after applying the keyboard, tethering fix, and sdcard swap. It will be perfect when I get this working on it. And if its true that having it odexed is faster, I don't know but it is very smooth and battery is awesome.

As evident from your last post, it does not work for you on UCLH2. As i said in my OP that i've not tested it on LH2 and it might not work as the android.policy.jar may be different. It should work on the UCLG9 and the ROM's based on it for sure.
I'll see later what i can do for the LH2. Can you post me a link of your whole system/framework folder, so i can download the same ? I'll maybe try later in the day to see the difference.

Deodexed your files and compared the PhoneWindowManager.smali file with mine, they are binary equals. So technically this mod should work for you. As your ROM is odexed, you need to manually delete the android.policy.odex and android.policy.jar file and then copy the android.policy.jar file from the zip attached to the OP. Remember to clear dalvik and cache partition as the last step before rebooting your phone. As Nardholio suggested this should work and you don't need to deodex the whole ROM.

Updated OP with the name of the ROM's tested to be working fine with this mod. Will try some more and keep adding.

Do not delete the odex file... in an odex ROM all the code, java and smali are located in the odex class until you deodex which pulls the classes out and compresses them into a classes.dex into the particular apk and/ or jar file. So, if you delete the odex file the jar or apk is useless as you just deleted all the java and smali code it uses to communicate with the DVM..

Deodexing is all clear and i know the procedure, but can you let me know some link or tutorial to follow to odex it back again ? I think it needs the whole rom and needs some more files like framework etc. to be odexed again ?
Note: still learning and long way to go

In my trying to learn all of this too, seems you can re-odex a rom. But everything I found has to be done on the phone it self with terminal and a odex wrapper script. Haven't found a way of doing it on a computer yet.

I've read some tutorials as well, but lemme know if you find a easier way to do this. I'm almost certain that the odex files are specific to a specific rom, but i can be wrong as well. That's the reason i believe that the generic mods are only for the deodexed ROMs.

Yes the odex file is specific per app so if any changes were made, the odex file which contains most of the data for each app would also have to reflect those changes. As the changes you made were part of .smali which is part of the dex file. So on a stock rom the odex file is loaded into the Dalvik machine during boot. This is why when flashed on a odexed rom the mod does not take, because the non modded odex file was already loaded. I gave up as I'm happy using literom4 with your mod.
Edit: Ok here is why it has to be done using the phone, all has to do with BOOTCLASSPATH http://classictomatoe.net/dexo-universal-odex-tool/
If you wanted to make this mod for folks still using the stock rom. All that needs to be done is decompile the .odex file using baksmali make the changes to the necessary files and then smali ?I think? don't quote me on that.

man,it wont deodex because apn of android is set on 15.so set it to 10.because you are using base rom gb(2.3.5)
then convert to deodex.
it wont covert to deodex by deleting odex files.and you need to convert framework and system apps both to deodex so click on b option.
and no need of app2sd because its very old method,wont work sometimes so better use link2sd or int2ext+ scripts.and yeah dont forget to add busybox run aparts(init.d) support or you wont able to flash int2ext+ scripts.
also change wipe status of rom.keep it to yes.so when you flash rom,it ll wipe all data remaining on phone
then make zip with option 2.edify sign zipaligned and all.
then flash it ll work.
