[Complete Guide] What is Odex and Deodex ROM?

[Complete Guide] What is Odex and Deodex ROM? - Galaxy S 4 Mini General

What is an ODEX file?
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.
What is an DEODEX file?
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.
So, 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.
How this works?
For the majority noobs amongst us, Android OS uses a Java-based virtual machine 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.
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.
Advanteges & Disadvantages
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.
Note:Themes for android come in APKs too, and if you want to modify any of those, you should always choose a dedoexed custom ROM.

What is Zipalign?
Zipalign is an archive alignment tool introduced first time with 1.6 Android SDK (Software Development Kit). It optimizes the way an Android application package (APK) is packaged. Doing so enables the Android operating system to interact with the application more efficiently, and hence has the potential to make the application and overall the whole system much faster. Execution time is minimized for zipaligned applications, resulting is lesser amount of RAM consumption when running the APK.
How does it exact work?
In an Android operating environment, data files stored in each application package are accessed by multiple processes, for example, the installer will read the data manifest to determine the associated permissions; the system server can read these resources for multiple reasons, like displaying notifications; the Home application, for example, will read resources to get the application’s name and icon. Since Android is based on a a true multi-tasking operating infrastructure, these files are continually and repeatedly accessed. Finally, but not least, the application itself reads the manifest data.
As Android is Linux-based, memory-mapping plays a key role in efficient handling of processes. Essentially, the optimal alignment for the Android OS’ resource-handling code is 4-byte boundaries. What this means is that, if APKs are memory-mapped to 4-byte boundaries, and aligned accordingly, the OS will not need to ‘read through’ the whole application package to get to the desired data manifest. Every system process will know in advance where to look for it’s desired resources, and hence will execute much smoother and faster.
Summing it up, zipaligning an APK results in all uncompressed data within the package to be aligned on 4-byte boundaries, allowing all portions to be accessed directly with the memory-map. RAM consumption is lowered while execution because the querying code doesn’t have to read through the entire application package.
Disavantages of unaligned APKs
Quite understandably, situation would be reserved for unaligned application packages. Resource reading would be slow and memory usage would be on the higher end of the spectrum. It would also depend on how many unaligned applications are present. For example, if less number of applications with an unaligned home application, you’d see slower application launch times. This is the best case scenario. For a worst case scenario, having a number of unaligned applications will result in the system repeatedly starting and killing processes, struggling with lags and huge battery drain.
How to make APKs zipaligned?
As mentioned earlier, the zipalign tool became a part of Android SDK from 1.6 onwards. It can be found under the ‘tools’ folder of the SDK. To use it, simply run the command:
zipalign [-f] [-v] <alignment> infile.apk outfile.apk
Click to expand...
Click to collapse
...where infile.apk is the source file, and outfile.apk is the output file.
You can also verify the alignment of an APK file using the following command:
zipalign -c -v <alignment> existing.apk
Click to expand...
Click to collapse
...where existing.apk can be any application package that you need to get verified. Also, the <alignment> tag in both the commands needs to be an integral value (otherwise the command will return invalid). This value, although can be any integer, MUST always be 4, which would provide 32-bit alignment. Any other value and it will effectively do nothing.
Finally, for the flags used in these commands,
-f - overwrites existing outfile.zip
-v - will give verbose output
-c - will confirm the alignment of a given file
Click to expand...
Click to collapse
CAUTION: Zipalign operation must only be performed after you have signed the APK file with your private key. If zipaligned before signing, the signing procedure will disturb the alignment. Same holds true for any other alteration, addition or removal to the APK file. Any change after running zipalign will undo the alignment.

[Script] VERY simple application backup script for ROM upgrades [not for newbies]

Hi,
I'm new to the business and I spent some time to learn the environment trying different applications and different approaches for almos every action I took. Today, I have not much bigger knowledge, but I finally decided to take few things in my own hands because existing software is not fulfilling my wishes.
I started with this simple script which eases the pain of reinstalling all applications after ROM upgrade. There are few such tools already, but I found those quite bloated with unnecessary thing for my own approach.
With this script I assume:
1. There is/was SSHDroid installed (or any tool with busybox and you can access shell command line) both in old and new ROMs and your ROM have bash installed in /system/bin/.
2. Backup/restore operation includes only INTERNALLY installed applications, it completely ignores SYSTEM and SDCARD installed ones.
3. This is TEMPORARY backup so it should be as fast as possible not caring about occupied space (!). Althought I added -zip parameter to enable compression if you are running out of space on your sd.
4. Installed ROM is clean with no additional apps installed (excluding those needed by the script)
5. You have basic knowledge about bash scripting, because I take NO RESPONSIBILITY of the script behavior or data loss it can do.
So, basically it is simple. It runs like this:
1. On old ROM type: sbackup -backup
2. Flash your ROM
3. On new rom type: sbackup -restore
Just like that. The applications data is tar'ed in one file per application so if you want to get rid of any, just delete it from backup directory. The directory name is same as script name on sdcard but you can change it adding a parameter without a '-' sign at runtime (first non-option parameter is treated as backup directory path). The file is zipped because this forum disallows files without an extension so... it is zipped ;D
It was tested on my fresh LeeDroid 3.3.3 GB AFTER i installed some apps. I backed them up and then restored. All seems to be perfect right now, but I will test it more thoroghly very soon because I'm planninig to have CM7 based ROM too just to choose that I need Sense or not (two nandroids for fast switch weekly ;P).
With this script and MyBackup functionality of backing up contacts, sms, history and similar it should be quite complete approach to restore all the data needed on the fresh ROM. In the future maybe I will look at the MyBackup part too. Maybe.
Feel free to comment, use, suggest or anything you like, and have fun ;P.

How do I run this script? Do i run it from sdcard or from system /bin? When i do it from system bin it says cannot create directory. When i run it from sdcard/sbackup it says permissions denied?

And thats why I mentioned in topic about not being a newbie (and I meant not forum newbie but more a linux newbie). The thing is, it's a simple script - without any user-proof capabilities, comments inside or something BUT...
But ok, I will try to help you run it. First of all, you have to set permissions to the script. It has to have executable permission to be run by the system (and I mean filesystem permission). This can be done by chmod instruction of busybox. Most of the times it's done like this:
chmod 755 filename
This is a reason of not running form sdcard if your sdcard is NOT ext filesystem (it is usually windows fat filesystem not to generate problems with reading it under windows).
Second thing to run is to have /system/bin/bash because first line of the script (a comment like this: #!/system/bin/bash) instructs busybox to execute script using bash. This can be simply changed by modifying this line, but you have to remember that changing the shell executing script have consequences. Differens shells have sometimes different syntax, althoght i wrote this script simply so it should run on most of them, especially sh.
Third thing is to have write permissions to the directory in which the backup will be created. In original version of the script it is /sdcard, because backup is made in /sdcard/sbackup. So, you have to check it (second error - problems with creating directory).
And a last tip - it can be run from ANYWHERE. Even if your partition does not alolow executing, you can do it like this:
bash-3.2# /sdcard/test
bash: /sdcard/test: /system/bin/bash: bad interpreter: Permission denied
bash-3.2# . /sdcard/test
OK
bash-3.2#
First try does not succeded, but second did. The trick is a dot which means to execute file with a shell not caring about why or permissions.
And thats most simple introduction I could write. It applies to ANY script you want to run.
Please anyone - if you want me to help, paste your results here because without a precise error message it can be very hard to deduce what caused for example permission denial or anything usual.
For now, I won't add any more error handling, but if there will be more users caring about, I will add it.

This can (in combination with tesseract-ocr) be very useful to recognize text from scanned images.
For pictures see also http://forum.xda-developers.com/showpost.php?p=23046120&postcount=187
Update 01/30/2012: Now with a small android app (ScriptStarter) to start services and other shell scripts easily from the GUI. See bottom of the post.
WHAT'S POSSIBLE WITH THIS SCRIPT:
With this bash script your are able to build relatively easy from source a lot of native software (over 90 at the moment) from the GNU/Linux community for your Android phone and you will have
the good experience with free software.
All these tools and programs are not "apps for the GUI" for Android but native running command line tools "under the surface" of your Android GUI like the kernel and other services.
Don't ask me if it makes any sense to install program xy (like MySQL) on a phone. This is your decision. It's possible, so try it and see what you can do with it.
Note: I tested most of the compiled software on a Samsung Galaxy S2 (my phone). I cannot test it on a variety of phones because I have no mobile phone shop...
Currently buildable with this scripts (abstract, see the full list in package_selection.conf):
PHP 5.3.10 (with almost all extensions and XCache)
MySQL 5.5.19 (if you want a full database server on your phone...)

FEATURES:
automatic download and untar the cross-compilers (if not already done) for cross compiling
automatic download and untar the source packages (if not already done), that you have selected
solve dependences and reserves additional needed packages
apply patches to the sources if necessary
build them, "install" them in a folder for later "ready to transfer" to your phone and stripes the binaries and libraries to reduce the filesize if selected
autogenerate a tar file and adb push the file to device if selected
allows you to use well-known software like PHP, MySQL, OpenSSL, OpenSSH, OpenVPN, bash and lighttpd on your phone (see the full list in file package_selection.conf, see attachement)
scripting and development on your phone
no limits with BusyBox (without want to be derogative, BusyBox is a wonderful tool), full featured tools like Coreutils, Binutils etc.
build scripts are expandable with other or newer packages you eventual want to have
QUESTIONS AND ANSWERS:
Q: Do I need native GNU/Linux programs and what is that?
A: If you do not know what native Linux applications are, then stop here - you don't need them.
Q: What can I do with these tools?
A: Many things. As a developer you can use the libraries to include them in Android GUI apps, as user you can start for example a webserver on your phone and write some HTML or PHP pages
just for fun or replace BusyBox with full featured tools (or only some commands).
Some tools are also very useful to find network errors, check the network traffic and many more.
Q: What do I need?
A: A Linux installation (VM or real), some Linux knowledge and a little bit time to read all instructions carefully. A rooted Android device with enouth free memory (ext2/3/4 formatted)
See README for details.
Q: Costs?
A: Nothing. The scripts are Open Source (GPL v3), the packages are GPL licensed or under a similar license. The cross-compilers are Open Source or free to use for non-profit purposes.
But I would be pleased if I get a donation and/or a press on the "Thanks button", if the scripts are useful for you. It was a long and hard work...
Note: The attachement scriptset-x.yy.zip is double packed (inside .bz2), because I want preserve the right settings of the scripts.
STEPS:
Selected the desired packages in the config file
Adjust the compiler settings for your phone
Run the build script to download and compile the software
Copy the generated TAR files to your phone or let "adb" this do for you and unpack them in the prepared sysroot folder
For more information please read the instructions in "README"
Please let me also know if you have any problems or if you have questions or further suggestions.
Thanks go to the Open Source community and a lot of people/webpages with hints about cross-compiling software.
Thanks

02/03/2012 Added a small ScriptStarter for the GUI. With this app, written with JQuery, PhoneGap and Java (wrapper to execute the shell scripts) it's possible to start for example the lighttpd web server, Pure-FTPd or MySQL from within the Android GUI without a terminal and read the output. If a script needs root access, there is a checkbox to allow this. For this to work, copy the script sush in the script folder. All scripts ending with .sh can be started (please choose after the first start your script folder on the device to add the scripts to the selection, normally your [SYSROOT]/sbin folder).
Three buttons (start, stop and status) are predefined for start-stop-status scripts, there is also a parameter input field for more start values.
Free GPL v3 source code also included (Eclipse project). Please don't expect too much eye-candy. The GUI could be much better, but my CSS skills are very limited...
I added a few example scripts in the zip file, for example a battery stats reader. Before starting these scripts, have a look in the source code to be sure that they are compatible with your device.
Update 0.97 02/03/2012: Now the stderr is also printed in the output window
Update 0.99 02/10/2012: Replaced scrolling api with a much better solution (jScrollPane) for the output window. Not the real Android scroll feeling, but it's usable.

Thanks! I would hit the Thanks button, but I am on my mobile atm.

Someone tried it? Problems?
Please, I need your feedback...

Sounds interesting, I'll try once I get back home and share feedback here

now i try to all packages for test
i will test on cortex a8 (motolora xt720)
TARGET_MARCH="armv7-a" (not work on armv7 )
TARGET_MTUNE="cortex-a8"
TARGET_MFPU="neon"
TARGET_MFLOAT="softfp"
it make dynamic binarys but i don't want dymanic type (because it difficult to divide one thing and maybe not work on android's libs)
how can i make static type?
ps : oh...it has so many comile error (even can't read or count all)

Click to expand...

I hope I understand your question. Why not dynamic?
Yes, you have to set the parameters for your mobile phone. For TARGET_MARCH try "armv7", for TARGET_MFLOAT "softfp" and for TARGET_MFPU "vfp" but check this last setting carefully for this phone.
It's very hard to build a full static binary (and sometimes nearly impossible) and it's also hard to build against bionic (with NDK). I had no good experience with it . A lot of compiler runs wasn't sucessful. Edit: I also had for example massive problems with openssl. I couldn't find a way to build it with NDK or static and then build other programs like cURL with openssl support.
Static binaries are also too big and not necessary. For this we have a sysroot environment to be independent from bionic and without the restrictions. The compiled libs and binaries are linked to the CodeSourcery glibc and have set the custom "rpath" for the dynamic loader. That's no problem I think.

that's simple
if someone want to make some binary for all version of android (even same cpu) it will not work well (defend on basic lib(ex : libc) is ok but complex things will not work)
i know make static type binary is very difficult but it valable

You are right, if you want to build a "portable" binary, you have to set very safe settings, like TARGET_MARCH="armv5", the full list is in the "README". But it's not my main target to offer a solution that is easy portable to other phones, instead you can build the software with optimizations for your phone to "get the best" for it

just i want to add some more function on the phone
thanks for patch files

I want to try this, to install some apps(most interested fro mc), but I don' t wanna change my sd card.
Can I use phone' s /data partition as mysysroot directory? I have 1.5GB space available on data partition, it is 2GB all.
And If yes, I must create the dir: /data/mysyroot? And where to create this dir on pc? On root directory of my linux system?

You can use the /data partition. Just create a new folder, for example /data/sysroot. On your PC you have to create the same temporary with full user rights. This is not your working dir for building. Create a new dir in /home/user and unpack the files there. In settings insert the /data/sysroot as TARGET_SYSROOT and change the other settings for your phone and choose mc=yes. Then start the ./build.sh

Thanks for your quick answer.
Just to make clear because my english understanding is not in a high level
I must create the /data/sysroot dir under "/"(root directory) on linux pc with superuser rights?

Yes, that is right. But this is the only step you need to do as root or better with root rights. After this work as usual as user.

Please notice first, that you should not run this script as root!!
Then there is something wrong with the build of the first needed packages:
ZLIB=yes
OPENSSL=yes
CURL=yes
GETTEXT=yes
LIBXML2=yes
READLINE=yes
NCURSES=yes
- The script cannot find the readline sources. Do you have a subfolder readline-6.2 in folder sources in your builddir? Same for the other source folders. The script first downloads the packages to folder packages, extract the tars in folder sources, repeated for all selections.
(look at line 67 in your log: ./build.sh: 1402: cd: Python-2.7.2: No such file or directory)
- You have no "xz", install it first and make sure, that the other necessary packages are installed. MySQL and gcc are "two pass" compilations and this builds generating temporary binaries, runable on your linux pc. So you need all for a successful compilation of such binaries like gcc, make, python etc. on your linux machine. If you are using Ubuntu, then install the "meta-package" build-essential, look in the README.
Do you have the other unpacking tools like gunzip etc. Please install also "bison"
You should do following steps:
1. First select only the necessary packages (see above), all others to no.
2. If zlib, python, readline an the others are cross-compiled (without errors) and the libraries are in ./sysroot/lib, then deselect them (=no) and select mysql=yes and start a second run with ./build.sh

Good luck!
If you can wait a little bit:
In a short time I release a new version with better error and program checks and some small bug fixes. With this version it's not longer necessary to edit the build.sh, it's now all in only two separated configuration files (configuration and package selection).

hmm...fail to compile mysql again

Hello dateno1,
first: you have *NOT* changed to a user account as promised
The va_list is only a note, not an error, no problem (but ask the MySQL devs why they haven't adapted the code to gcc 4.6.1).
Your Python cross binaries and libraries are not ok (from you broken first build?). Please start from a "fresh state" (delete the folder sources/Python-2.7.2 and sysroot) or start from a total clean state.
Please use the latest 1.5 version of the script because of the xargs warnings at the end
Delete the complete sysroot folder, there are some folders not in place (data and docs). There is a script remove_all_files.sh
Start this script in your buildroot with ./remove_all_files.sh to remove all files and symlinks in subfolder sysroot.
Edit: delete the sysroot folder complete, there are some other missing folders from your first build!
Start again with ./build.sh and activated packages (the "ALWAYS NEEDED" one and MySQL)

[TOOL][SCRIPT] ADB Sync Tool - PowerShell Script

This is the first time I have posted any of my work, so hopefully I have it in a suitable place.
This script is to sync directories from an Android device to a windows machine. This is a one way sync, and will only copy the files which have been changed on the device. Thus making the whole process much quicker.
This script has been tested by myself using a SGS3, however I cannot guarantee this script will work as expected for any other device as I haven't had it tested.
Please report any issues to me, with as much information regarding the problem as possible as this will give me the best chance of fixing the issue. Same goes for any feature requests or improvements. I wrote this for own needs, but felt might be useful for other windows users out there.
ADB must be on the windows PATH. See link -> http://www.computerhope.com/issues/ch000549.htm
PowerShell's Execution Policy should be set to RemoteSigned. See link -> http://technet.microsoft.com/en-us/library/ee176961.aspx
This script takes a CSV file and should be called in the following manor using a powershell console
Syntax: .\adbsync.ps1 dirs.csv
Where dirs.csv is a csv file with two columns. The first row contains
the headers "source" and "target". Each following row contain the paths.
example csv file (file also included in the zip)...
Code:
source,target
/storage/extSdCard/TitaniumBackup,.\Sync\storage\extSdCard\TitaniumBackup
/storage/extSdCard/clockworkmod,.\Sync\storage\extSdCard\clockworkmod
This will sync the TitaniumBackup directory on the external sdcard
to a folder called Sync keeping the same structure as on the device.
You only need to specify the top level folders as this script will recurse the folder structure.
WARNING: This script will remove files from the target directory without prompt
if the files in that directory don't exist on the source directory.
Nothing will be removed from the source directory.
This script is provided as-is, no warrenty is provided or implied. The author is NOT responsible for any damages or data loss that may occur through the use of this script. Always test, test, test.
This script is free to use for both personal and business use, however, it may not be sold or included as part of a package that is for sale.

[TOOL][WIN]DroidShell - Windows Shell Integration for Android Development[02/02/16]

Greetings, and welcome to the home of a little set of utilities I'm calling "DroidShell".
What it is:
DroidShell is my attempt at bridging the gap between the various android utilities used for ROM modification and the Windows explorer system. It is a series of scripts that are automatically associated with .apk, .jar, and .iso files so that they are automatically decompiled on double-click or enter. Additionally, when a file is decompiled, a corresponding .dcp, dcf, or dci (decompiled package, decompiled framework, decompiled image) file is created, which allows for automatic recompiling, as well as optional cleanup, or resigning.
The goal of this project is pretty simple...to have all the tools needed for ROM work in one place, and have them easily accessible without having to have eighty command windows open or to have to go through a chain of commands to create a usable apk/jarfile.
Features:
One-shot setup. Extract the files, run install/installer.bat, and all of the necessary file associations and paths are created.
Batch terminal integration - provides integration for adb, fastboot, apktool, 7zip, zipalign, oat2dex, unpackbootimg, repackbootimg, baksmali and smali in windows command-line interface from path.
Automagic association with common android filetypes for decompilation.
Custom placeholder files - dcp, dcf, and dci - for packages, framework, and image files. Allows for automatic recompiling, and optional signing and cleanup of decompiled files.
Recompiled apks and jars are automatically repacked with modified files while excluding androidmanifest.xml, meaning signatures are unaffected.
For modifications requiring androidmanifest be changed, you can right-click a .dcp file to recompile with signature.
Auto-detection of framework-res file with prompting to install.
Popup dialogue boxes for errors and alerts.
(NEW) Right-click to decompile to java code. This cannot be recompiled, but is great for researching more complex mods. (Can also be invoked by using the command dj filename.apk)
(NEW) Support for sparse image system -> .img conversion.
(NEW) za command for zipaligning apk's.
(NEW)
Download:
https://github.com/d8ahazard/DroidShell/archive/master.zip
Source:
https://github.com/d8ahazard/DroidShell
Instructions...
You need the Java Runtime Environment (RE). Get it here.
Extract to a folder somewhere. Spaces in the path are probably not good. I put it in C:\DroidShell
Browse to the folder. Go into the install folder. Run installer.bat. (Installer needs admin priveleges. It will prompt for them, but in some cases, you may have to automatically run as admin)
Reboot.
You should now have shell integration. APKs, Jars, and .img files will automagically decompile.
It's late, I've been working on this all weekend...but it should be good to go. Please let me know if you have any thoughts.
CHANGELOG:
Code:
02.02.16 - v2.0
Update smali, baksmal to v. 2.1.1.
Add shell script for oat2dex (not implemented in context menus, just avaialable for now)
Update APKTool to latest version
Add dx.jar - for converting java classfiles to .dex (just available for now)
Add ext4 and ext2 tools - For manually unpacking images if needed. These are GUI based, not my work.
Add rimg2sdat - For converting .img to sparse (Not implemented yet)
Update sdat2img to latest version by xspirit, added python to installer as required.
Add zipalign function (Not implemented, can be called via "za filename.apk"
Add decompile to pure Java:
This utilizes a few tools to take apk's and jarfiles and decompile them to as close of an android package as we can get without having the actual source code. While we cannot at this time recompile these into apk's, it is very useful for analysis when trying to implement other mods. Like...really helpful. This one can be accessed by right-clicking a decompileable package and picking "decompile to java".
01.31.15 - v1.8
Added windows progress bar for file copies in system.img extraction.
Fixed some script errors.
01.29.15 - v1.7
Cleaned up installer, added more verbosity.
Better error checking in image extractor.
Add support for .list files, allowing double-click extraction of system.transfer.list and cm12-style image files.
Added custom language files for notepad++, allows syntax highlighting of .smali and logcat files.
01.27.15 -v1.6
Added support for system images. Requires installation of included OSFMount.
Added file associations for common plaintext android files to notepad++ if installed.
Converted several .bat files to .exe, allows for icons, inclusion of required files, and UAC prompting when needed.
01.26.15 - v1.5
Fixed fatfinger in APKtool detection causing error.
01.26.15 - v1.4
Added zipaligning
Added check to make sure apktool is present
Updated test-keys to latest AOSP version
Compiled batches to .exe with required files for AIO-packages
Fixed: Installer not always associating with files correctly.

Thanks a million

Version 1.5 uploaded.
Added Zipaligning
Check to make sure apktool.jar is found in %DROIDROOT% directory.
Updated signing keys.
Switch from .bat to .exe, allows modularization of functions, cleaner.
Modifications to installer to try and fix some issues with file associations.
Fixed issue between 1.4 and v 1.5 where I fatfingered a check.

Hell yes!

So many thanks for this! I'm going to use it like hell!

Excellent Job!

I'm bookmarking this, gona read it thuroughly at breakfas

So I'm curious - has anybody had a chance to give this a try yet?
Testing file association stuff is tricky, because Windows likes to keep track of the "user selected" association too. So, I had to add some extra commands to the installer script to clean up everything appropriately first.
Either way, I've ran it on like three different computers "clean" and had it work like a charm on all of them. I'd like to know how it works with WIndows 7 or XP.

I could be doing something wrong (windows is not my OS of choice, I use kubuntu 14.10 as my daily driver, and as such am mostly illiterate in dos/batch, I'm a sh/bash guy), but the installer bombed out (hung up without confirmation of success) on my windows 7 pro install (on a dell latitude e6400, with a dual core core2 @2.8ghz, quattro 160m graphics, 4gb of ddr2 @800mhz, booting off a 120gb Samsung evo ssd. Wouldn't think its relevant, but just in case).
Steps:
First I decompressed the .zip in the root of my C:\ drive, with 7zip (did not change file name, kept as "DroidShell_1.5").
Next I ran the installer script.
I then granted it admin privileges.
It killed my desktop, explorer.exe. I assume this is normal due to the terminal output:
Code:
SUCCESS: The process "explorer.exe" with PID 3260 has been terminated
Then I got:
Code:
file type 'apk_auto_file' not found or no open command associated with it.
Followed by 4 more identical errors, just replace "apk" with dfc, dcp, dci, img.
A bunch of successful operations.
Then:
Code:
ERROR: Invalid syntax.
Type "REG ADD /?" for usage
A bunch of successful operations.
Then:
Code:
ERROR: The system was unable to find the specified registry key or value.
The above output repeats 17 times.
Then 4 more operation success messages and it hangs, with my desktop killed.
Ctrl+alt+del, logout, log in, and I'm back in business. No noticeable increase in disk space, no newly installed programs (as expected).
I read the op, and from my understanding it doesn't require any dependencies? (Apktool, android SDK, android studio, etc). All the necessary dependencies are built in, right? It's a fresh install of windows 7 pro, with all available updates taken.
EDIT:
It worked perfectly regardless of the errors, see my post on page 2.

Bombed out is a rough term. The installer is just writing a bunch of registry keys, and deleting some other ones to make sure other associations don't mess it up. So, some registry operations don't always work - there just there to be sure. I've actually worked on cleaning that up in the next iteration I'm cooking.
And yes, there shouldn't be any more size increase past extracting the original zip. All the files used are enclosed. "Installer" is just telling Windows that "droid shell is at location %CD%" and "use app xxx in %CD% to open file XX". A few extras for the right-click context menus and icons...so forth.
So, to know if it is working is really just a matter of finding an apk or .jar and double-clicking it. You should get a terminal window showing the process and a box confirming success or failure, plus a reason why if failure.
The only dependency is the Java Runtime environment, which is the same common necessity as for any other Apktool environment. You can get it here, and I'll throw that link in the OP in a second.
The next iteration of the installer is going to be a lot cleaner, plus be more verbose so you actually know what it's doing. My first thought in putting it out was just to see how well the decompile/recompile stuff worked.

I didn't mean to offend with the term "bombed out", it may have been a bit of a rough term. I just meant the script terminated my desktop and hung up.
It actually succeed regardless of the errors, and is working like a charm. I apologize, I should have actually tested it before posting. I shouldn't have assumed that it didn't work based off of the terminal output/behavior.
Also, I would like to say that I greatly appreciate the work that you put into this, and all your other projects here on xda. I'm running your 4.4.4 gpe port for the verizon m8 as my primary rom, and it is by far the most stable port I have ever had the pleasure of flashing.
Attached are screenshots of DroidShell successfully decompiling and recompiling an apk with a simple right click selection on windows 7 pro. Good stuff.

Thanks! tons

Thanks for the work. very useful.
The compiling and decompiling of apk is perfect on Win 7 pro.
From the OP, i also got the impression it would unpack / pack images, so i tried it with a system.img copied to the droidshell directory.
With the command c:\droidshell\unpackimg system.img, I got the error as shown in screenshot
Am I doing something wrong, or is this not supported yet?

Oh, no offense taken.
I came at this project, as I do with most, with the mindset of "OOOH, SHINY THING. I MUST SHOW EVERYONE." So, first thought was putting out the app, despite some of the install stuff being a bit dirty.
However, the next iteration is shaping up to be quite lovely. See below.

So, it appears that this question has motivated me to try making that function a reality sooner than later.
However, as far as I can see, the *ONLY* application for windows that currently deals with system images right now is Ext2Explore, which is a bit old and doesn't have command-line support.
Fortunately, there's source code for it, so I'm currently downloading Visual Studio and will see if I can add command line functionality, as well as make it launch with UAC prompting.
If I can make this work, my plan is to make one handler for .img files that works like so:
1. Look at the file passed to it and see if it's a boot image. If it is, extract and exit.
2. If it's not a boot image, try to extract it as a system image. If it is, extract and exit.
3. If it's not a boot or system image - pass it to explorer and mount as usual.
I can do # 1 and #3 already...it's just getting #2 to go.
Also, I've added a check in the installer that looks for the installation of notepad++. If it finds it, it will create additional associations for .xml, .prop, conf, config, .smali, and whatever else I can think of that I could possibly need to edit in a ROM.
Then, lastly, with all these additions, I'd like to make the installer a bit more verbose. Give some options so it's not just an all or nothing install, make it prettier, etc.

Don't get too excited. I've never touched C++ before, and ext2Explore was done in VisualStudio.net and a WYSIWYG editor called QT. I found updated source for the program from 2012 and have gotten it to import into QT, however, it needs MingW and some other dependencies. I'll be lucky if I can even get it to compile again, let alone work, let alone work with added command-line stuff.
However, that's still the goal.
Also, I want to add wget (windows equivalent) stuff to auto grab and install java and notepad++ while we're at it.

So, I think Ext2Explore is more work than it's worth.
OSFMount, on the other hand, just let me mount a system.img as a removable disk with read-write access. I'm going to go down this road...

Good to hear that. Extracting system.img on windows can be a real pain at times - this would be great.

[TOOL] [Windows] Batch APK Zipalign Tool v 2.0 (23/05/2022)

What's ziplign ?
Read,Android Developers site.https://developer.android.com/studio/command-line/zipalign
zipalign is an archive alignment tool that provides important optimization to Android application (APK) files. The purpose is to ensure that all uncompressed data starts with a particular alignment relative to the start of the file. Specifically, it causes all uncompressed data within the APK, such as images or raw files, to be aligned on 4-byte boundaries. This allows all portions to be accessed directly with mmap() even if they contain binary data with alignment restrictions. The benefit is a reduction in the amount of RAM consumed when running the application.
This tool should always be used to align your APK file before distributing it to end-users. The Android build tools can handle this for you. Android Studio automatically aligns your APK.

Why this tool is needed ?
There are a lot of APK modifications on XDA, most of which are done through APKTOOL (Thanks @iBotPeaches for this great tool)
But after apktool compilation, apks needs to be zipalign manually -> which is missing from some these Modded/Distributed Apks found in the forum.
So, I decided to go ahead and make simple tool for this task.
This tool will help end-users/devs in such cases.
How to Use ?
It's One-Click tool, As simple as it gets !
Download & Extract Zip file from attachment.
Put All apks in "Input" folder
Do not leave "SPACES" in file name of APKs For example, Use "AppName_v1.apk" instead of "AppName v171.apk"
Double Click the Batch file (.bat)
You can find zipaliged APKs in "Output" folder after it's done.
That's It !!
PS : (Devs only) Use this tool **AFTER** signing APKs
Users don't need to worry about this because APKs you have/download are already signed.

FAQs
# How to know whether APKs are zipaligned or not after using this tool ?
Check file size of APK Before & After (In Input & Output folders). You will see the differnce in file size on bytes level So, you need to open full property of file via right click.
If file size if exactly the same, means APK was already zipaligned
# How to know whether APKs i have are already zipaligned or not ?
As of now there's no method to my knowledge. So, you need to go through above process.
In general, APKs directly from PlayStore (you backup/apkmirror) are zipaligned so you don't need to zipalign them unless there's some modifications performed on it.

I'm not actively maintaining this tool due to personal commitments. Theoretically it should still work even with older binaries but if you are looking for specific support I suggest search for other/newer threads.

i get this error a mod apk
Code:
Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES: Failed collecting certificates for /data/app/vmdl262490375.tmp/base.apk: Failed to collect certificates from /data/app/vmdl262490375.tmp/base.apk: META-INF/APKEASYT.SF indicates /data/app/vmdl262490375.tmp/base.apk is signed using APK Signature Scheme v2, but no such signature was found. Signature stripped?]

Command file current zipalign.bat:
for %%X in (.\Input\*.apk) do (
echo Zipaligning - %%~nX.apk
.\Tools\zipalign -cv 4 %%X
.\Tools\zipalign -fv 4 %%X .\Output\%%~nX.apk
)
Maybe it should be reversed like this:
for %%X in (.\Input\*.apk) do (
echo Zipaligning - %%~nX.apk
rem To align infile.apk and save it as outfile.apk
.\Tools\zipalign -fv 4 %%X .\Output\%%~nX.apk
rem check alignment outfile.apk only after having zipalign (does not modify file)
.\Tools\zipalign -cv 4 %%X
)
