I just edited a patch.obb of a game but when I run the game with normal APK it says that the game needs to download additional content. What do I need to edit in the apk for it to get my EDITED patch.obb to work?
I know how to decompile and compile apk. :fingers-crossed:

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?
hey all, i was just wondering if anyone knew how to extract some files from an apk?
specifically, i like riptide gp's background music and was wondering if anyone knew how to extract those music files from the apk or something. let me know! thanks!
I already tried opening the apk on both my computer and NT and couldn't find any music files anywhere... starting to think its not possible, but it can't be because in order for a game to have music its gotta have music files somewhere in the installation file just like any other game on any platform...
Just to get the most basic question out of the way, so sorry if I seem pedantic, but did you just change the extension of the .apk to .zip or did you use APKTool to unpack the .apk?

i've already tried extracting the apk by conventional means, aka using winrar to extract the contents, but no luck in finding any files resembling that of a music file type. i've also tried apktool but after decompiling the apk, i couldn't find any music files either...
after decompiling through apktool i just saw a lot of .smali files. there was one files called base.apf but not sure how to decompile that....
Check out apktool to extract apks. I've used it on system files to open them up and edit what's inside.

Hi everyone,
From my understanding, if we want to change the pngs in an apk, we can simply open it with 7zip, then replace the pngs, it's done.
I took EventStreamPluginCallLog.apk from arc s which is updated to ICS.
The apk can be installed in xperia s and it is working fine.
However, when I change the png named icon in res > drawable-hdpi > icon.png
The apk can no longer be installed.
So I go with decompiling and recompiling the apk using apktool, no error shown but I still can't install it
Any idea? Thanks
did you sign it after recompiling?
System apps don't need to be signed. What i did for system apps is:
Decompile app
Replace png
Recompile app
Use TickleMyAndroid -> Prepare files for pushing.

I thought the same even it says no need for system apk, I still do it and get the same problem, can't install

I tried everything I know. Apk Multi Tool, simply apktool only, direct replace PNG with 7zip (compression changed to deflate), direct replace with winrar (compression method retained as store), it just doesn't want to install.
I have tried TickyMyAndroid, I am not sure if I done thing correctly but I see no error when recompiling yet can't be installed. My goodness. Time to forget about this stuff
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.
