Deodexing? Fundamental and How to.

Well , since most customization for custom roms require a deodex device , lets first understand the fundamental of the file naming system in android devices. Below is the understanding of the odex and deodex file. Well some of us wanted to use stock rom but to have the ability to customized it with theme and a few other mods. So here a fundamental of it and how to deodex your system.

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.

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.

For the more geeky amongst us, Android OS uses a Java-based virtual machine for running applications, called the Dalvik Virtual Machine. A deodexed, or .dex file contains the cache used by this virtual machine (referred to as Dalvik-cache) for a program, and it is stored inside the APK. An .odex file, on the other hand, is an optimized version of this same .dex file that is stored next to the APK as opposed to inside it. Android applies this technique by default to all the system applications.
Now, when an Android-based system is booting, the davlik cache for the Davlik VM is built using these .odex files, allowing the OS to learn in advance what applications will be loaded, and thus speeds up the booting process.
By deodexing these APKs, a developer actually puts the .odex files back inside their respective APK packages. Since all code is now contained within the APK itself, it becomes possible to modify any application package without conflicting with the operating system’s execution environment.

The advantage of deodexing is in modification possibilities. This is most widely used in custom ROMs and themes. A developer building a custom ROM would almost always choose to deodex the ROM package first, since that would not only allow him to modify various APKs, but also leave room for post-install theming.
On the other hand, since the .odex files were supposed to quickly build the dalvik cache, removing them would mean longer initial boot times. However, this is true only for the first ever boot after deodexing, since the cache would still get built over time as applications are used. Longer boot times may only be seen again if the dalvik cache is wiped for some reason.
For a casual user, the main implication is in theming possibilities. Themes for android come in APKs too, and if you want to modify any of those, you should always choose a dedoexed custom ROM.

##Your Device Must be rooted for this process

13.Enter following codes.
(if you are using adb shell in su for the first time, keep phone screen on. After entering "su" code, super user request prompt in phone. Press allow )

adb shell
stop mount -o rw,remount /system/ /system/
cp /sdcard/done_app/* /system/app/
rm /system/app/*.odex
cp /sdcard/done_frame/* /system/framework/
rm /system/framework/*.odex
mount -o ro,remount /system/ /system/
14.Now you have deodexed rom.

Google Android Hidden Secret Codes

So in this topic, you'll get several hidden secret codes which can be used in any Google Android mobile phone to access things which are not accessible by default.
FYI These codes have been obtained by decoding various .apk files present in the phone firmware.
