So I've decoded a launcherpro apk and gotten all the files inside.
I've edited them changing only some images(not .9.pngs) and some text strings for a translation.
I don't really know how to re-encode the file and sign it.
I tried using APKtools to repack but ASTRO won't let me install it saying it can't open it as an apk file.
Any help is appreciated
i cant get apktools to do anything other than decompile...
if you got it to compile your apk but dont know how to sign it, use this: http://androidforums.com/developer-101/8665-how-signing-roms.html
its what i use to sign zips and apks and it works very well and is easy. the "auto sign" or qwhatever opetion doesnt ever work for me, but option 4, manual, works fine
if you havent installed the framework-res.apk that may be why you cant compile
what you need to do is pull out the framework-res.apk and put it in you root directory then in terminal use this.
code: apktool if framework-res.apk

Hi, i am trying to modify the classes.dex file in an apk but it is giving me problems.
if i decompile the apk and recompile it after modifying the app installs but crashes after one minute. also some functionality in the app is also lost.but when i binary edited the classes.dex file and replaced it in the apk ( i have used different methods for replacing the .dex such as direct replacing in archive and replacing in the decompiled archive) the app doesn't install and the phone or emulator reboots. i have done this with other apps and they are working fine after editing so i couldn't understand what's going wrong. please help
You should use a decompiler and achive to the java code. Than you can easily modify and recompile the app. You will need an Linux virtual machine to do this.
In linux, after you found you .apk file use this to decompile it to a .jar file. http://siis.cse.psu.edu/ded/installation.html. After that, you can use http://java.decompiler.free.fr/?q=jdgui to browse the code. With this method you will need a Linux machine and would give you the best result.
If you want to use windows, follow this tutorial http://androidorigin.blogspot.com/2011/02/dex-format-to-jar-format.html but I warn you, its likely to be faulty.
Hope this will help you.
thanks for replying
i used apktool to decompile and modify the smali code. i had even tried converting the smali code to java but no help.the problem is that the recompiled app runs only for one minute and then crashes without any error message even logcat log is not of help it just says that the process xxx has died but no err msg or exception is logged. if i replace the classes.dex with the patched one and then re-sign it it does not install and crashes the emulator but when i again decompile and then recompile the modified file it return to the same old problem of crashing. do you know how apktool packages the compiled files?
You should follow one of the tutorials posted in my last post. I did not used apktool and I don't know how it works.c the method with that decompiler will work. If you want your application signed just sign it as a normal one.
this particular apk loses about 20-30 kb in filesize on decompiling and then recompiling with apktool while this is not seen in any other apk. maybe this means that this file has some overlay data that goes missing on modifying and creats problems.7-zip is unable to show any extra data in the file.does anyone know how to add and extract overlay data on/from an apk?
I got this figured out already, sorry about that.
Who ever thanked me, I wasn't posting a guide but a question.
I am trying from a fresh firmware base to learn from scratch but no idea how to get that framework to compile correctly.
did you install framework first?
Code:
apktool if framework-res.apk
Easy
I had problems with the apk tool and recompiling. The way I ended up doing it is:
I didnt decompile the framework-res.apk.
rename the file framework-res.apk.zip
open it with 7zip.
Extract the files you are wanting to work on
Do what ever work on the files you need done
Drag and drop the files back in the directories they go into while file is open in 7zip
Close 7zip
Rename file back to framework-res.apk
push to phone with adb
No decompile or recompile.
Hope this helps

If you just want to modify one of the 'normal' XML files or an image then that approach will work fine. The problem is he wants to edit the bool.xml file and that is contained in the 'resources.asrc' file and you need to decompile it first.
I am in the same situation although someone managed to edit the file for me and recompile it so I got there in the end, just not by doing it myself.
I followed the instructions you describe and the file never recompiled properly - or at least my device never booted with the one I recompiled
Try it like this:
1. Place APK in "place-apk-here-for-modding"
2. Choose "9" to Decompile
3. Grab resource "resources.arsc" from framework-res.apk
4. Do my edit in projects\framework-res.apk\res\values\bools.xml
5. Compile - Yes (system app) - Yes (copy files)
6. Go to "keep" folder and delete "resources.arsc" and the bools.xml file
7. Press any key
8. Either push by ADB or Root Explorer or Flash

I have tried exactly like this and it didn't work for me. I downloaded lots of different APK tools and tried them all - there were comments about using older versions of apktool.jar etc. I kept getting different sizes of the output file depending on which one I used. I gave up in the end as someone edited the file for me and it was only one specific entry in bool.xmls I wanted changing. As far I could tell we were both doing exactly the same thing.
The last thing I said I was going to do was wipe the PC I was attempting to do this on. I never got round to doing it... I'd be interested to know why I could never get this working though

Hello ,
I want to install this mod -- > http://forum.xda-developers.com/showthread.php?t=1695202
I decompiled SystemUI.apk and changed bools.xml by Notepad. And I returned script.bat and I selected Compile apk. But error. I tried lots of apk manager but error.
On Notepad , need changed Coding / Character Group ??
If I open apk manager and I saw ADB not found. But apk manager is working , I selected decompile apk , Apk manager decompiled systemUI.apk but I can't compile apk. Thank you..
Ok if i remember correctly, you can open the apk with 7zip, modify the files you want to and they should work. I tried this with systemui.apk before and it worked..

I have had issues in the past using notepad to edit apk files. I suggest that you use notepad++ for editing xml and smali files. It can be easily found with a Google search. Using notepad will probably give you formatting issues.

ok heres my problem, i downloaded apk multi-tool, and everything was working right, but after few days, i tried to modified this app, but whenever i apply the option "decompile" the cmd window close by itself, without saying theres an error... do you guys have any idea about whats going on???
I'm no expert, but this is how I used to decompile APKs:
1) Rename the file "ABC.apk" to "ABC.zip"
2) Open the zip file
3) Copy out the file "classes.dex"
4) Use dex2jar (search Google for some tutorials) to convert it into a jar file
5) Use jd-gui (search Google for some tutorials) to decompile the jar file
the apk tool from Google or apkmulti which one did u use sir ..??
i fixed my problem, one of them was the system variables path "C\\windows\system32" the 2nd was because there was an space in the name of the apk i was trying to decompile.. thank you for taking your time to answer...
I wanted to change the graphics of a certain app to my liking. But I guess it can't be achieved in the non-system apps at least not by me. I tried the apktool to decompress it and then edit the the files I needed to, but it won't compile back?! Can anyone tell me what is going wrong. I have attached the whole screenshot of what error my apktool is showing me.
Also in the build folder I'm only getting classes.dex file and nothing more.
