So i have this Deskclock.apk and i want to add this.
No Problem with the ".xml" Files. I can edit them easily after i decompile the apk with the "apkTool". But where will i find the ".java" Files? After decompiling the apk i only see ".smali".
So i found out that the ".java" files are in "classes.dex" from the apk.
I use "dex2jar" to get a ".jar" File.
Then i use "jd-gui" to get ".java" Files.
So i can edit it and put the needed Strings in the .java files.
But how to put them back to a "classes.dex" File which i can put back to the apk??
I hope i get a bit help here.
You can use APKTool. It will automaticly extract all the classes (.dex), resources (.asrc), then it will convert binary XML to human-readable XML, and it will also dissassemble the classes for you.
Just tell APKTool to decode the APK into a directory, then modify what you want, and finally encode it back to an APK. That's all.
Important: APKTool dissassembles. It doesn't decompile. The generated code won't be Java source. But you should be able to read it, and even edit it if you're familiar with jasmin. If you want Java source, please go over the Manual way.

Thx...I know how to use APKTool but i need to put the ".java" Files back into the "classes.dex". Thats my Problem.
There's info on the process here: http://stackoverflow.com/questions/10261147/converting-java-back-to-classes-dex
Essentially it looks like you need to compile the .java to .class files with javac and then create classes.dex with dx. Hope this link is helpful.

Hello, i'm new with editing .jar files, and i have a question:
first of all my steps:
classes.dex
dex2jar Program
get .jar file
used Java Decompiler for src-jar.jar file
now i'm trying to figure out how to compile all the steps back into classes.dex file.
for more understanding of my question:
Decompiled "Camera.apk" and disassembled the "classes.dex" file...
I don't want to use APK Multi-Tools or APK_Manager or whatever. I want to know exactly what those tools are doing in order to recompile the system apk while keeping the original signature.
What I initially did...
Code:
apktool d "%~dpnx1.apk" "%~dpnx1"
...modify files here...
apktool b "%~dpnx1" "%~dpnx1.apk"
But obviously that's unsigned. I need to sign it, but I want to use the original signature, which I'm guessing is the META-INF stuff, right?
So I attempted this...
Code:
apktool d "%~dpnx1.apk" "%~dpnx1"
7za x -o"%~dpnx1-signature" "%~dpnx1.apk" META-INF -r
...modify files here...
apktool b "%~dpnx1" "%~dpnx1.apk"
7za a -tzip "%~dpnx1.apk" "%~dpnx1-signature/*" -mx9
You'll notice I now use 7-Zip to pull out META-INF from the original APK and then insert it back into the recompiled one afterwards.
The only other thing I can think of would be to go with my first method, but then use 7-zip to pull out the compiled files from the unsigned apk and insert them into the signed apk. I haven't tried that yet, but it will be the next one I go with. Every time this fails, though, I have to do a nandroid restore, and it's getting a little frustrating, which is why I'm asking you folks.
--
edit: I got it all figured out.
For those interested, after running "apktool b" (to build/compile), ignore the output zip. Instead go into the source directory and there is now a build directory. In that is an apk directory. Simply add your changed files to the original untouched APK (if you modified any XML files, then replace resources.arsc; if you added anything to smali, then replace classes.dex; if you added any XML files, then you need to include those as well; for me, i copied resources.arsc, classes.dex, and one new XML file). I used the following command:
Code:
zip -9 ..\SystemUI.apk res\layout\status_bar.xml classes.dex resources.arsc
I use zip instead of 7za for cosmetic reasons. You can also use "7za a -tzip etc..." if you want.
hello i know how you feel well....i never did.
you keep a backup and a copy of your system apk and once you did your changes look in your copy and go to /res and delete the destinations you modded and putted them in the modded apk now look into your modded apk file in /res and take the files you deleted from the copy apk and move them to the copy apk and your all set.
if this didnt understand ill show you an awesome thread that will help you
sorry i didnt see your edited section
Hello everyone,
I hope I'm posting this to the right forum.
Up until Android 4.4 KitKat we were able to use apktool for decompiling an apk, making modifications and then recompiling it.
In case we were dealing with an ODEXed ROM, we could also use backsmali and various other tools to deodex before using apktool.
Now, in Lollipop, which uses ART, we get an APK file, but also a .odex file in a '/arm' subfolder.
From what I've read so far, that's not really an odex file, but rather an Android runtime .OAT file.
My question is - how does this affect our abilities to edit APKs?
Is it possible to "deodex" the OAT file to get an all-inclusive APK to use with apktool? If so, how?
After we rebuild the APK, can we just run it 'deodexed' or do we need to recreate an OAT file?
Any insight would be appreciated

Files needed:
1. bootoat2dex.jar
2. Cygwin
3. APKTOOL
4. Java will need to be installed also
Install Cygwin and run it once so your userfolder is created, will be in c:/cygwin/home/<User Name>
Copy bootoat2dex.jar into this folder
Go to priv/app/SystemUI/arm/ and use 7zip to extract SystemUI.odex from the SystemUI.odex.xz file
Copy SystemUI.odex to your cygwin folder c:/cygwin/home/<User Name>/
Open cygwin and run the following command:
java -jar bootoat2dex.jar SystemUI.odex
This will output 2 folders dex and odex, if you look in the odex folder you should see SystemUI.odex.
Rename this file to classes.dex and drop it into the SystemUI.apk file
Follow the same instructions for the twframework-res.odex file also.
now copy the files SystemUI.apk, framework-res.apk and twframework-res.apk into you apktool folder and install framework ex. apktool if framework-res.apk, apktool if SystemUI.apk, apktool if twframework-res.apk
After the framework install you should be able to decompile SystemUI.apk, you should be able to do this with all the apk files.

Great info! Thanks! I have used oat2dex.py to extract the OAT file, baksmali'd, modified smali code, recompiled it but that's where I'm stuck. How do I get it back into the original OAT format for inclusion in an Odexed rom? Any help would be greatly appreciated.
P.S. I'm working with SystemUI.odex.

Hey
I am currently struggeling at editing a xml file in an .apk that i got.
I've used this Jadx decompiler (wwwDOTjavadecompilersDOTcom) to decompile the apk, which gave me the following files and folders:
fs5.directuploadDOTnet/images/160129/ypnqz7xuDOTpng
All the files are human readable.
But how do I recompile it? Can I load it into the Android Studio?
fs5DOTdirectupload.net/images/160129/ho4vszubDOTpng
As you can see importing into android studio did not really work. The app couldn't be run.
Search for apktool here. It is what is used for decompiling and recompiling apks.
Hi guys,
Can you tell me how to decode and Encode file AndroidManifest.xml in folder Original after decompiled a apk by apk easy tool ?
Tks!

Weird, AndroidManifest.xml is supposed to be decoded. The fact that it remains in the original folder is weird, did you try doing it with apktool only ? (With apk easy tool)
Super simple, just install apktool (if not already installed and working without apk easy tool)
To test if it's working without APK easy tool open a command prompt and enter "apktool --version", if it returns something, then it's good, if not, you're good to set it up yourself in a separate folder, here is the guide from the apktool website: https://ibotpeaches.github.io/Apktool/
Enter the command "apktool d [name of the apk].apk" to decompile your apk, you should have everything.
And if you don't want to bother your with all of that, I can decompile the APK for you and send you the AndroidManifest.xml file decompiled.
Have a good day

Thanks for your reply, I have tried to decompile that apk by your way but file AndroidManifest.xml in folder ...original\AndroidManifest still be encoded. Can you help me decode it as you said that ?
Link down this apk :drive.google.com/file/d/18HjRivgkNjixCdO823CJD2mxLxr6QuEQ/view?usp=sharing .Remember that I need to decode file AndroidManifest.xml in folder original which contains both of folder META-INF

That's a huge apk, what is it? 1,2 Gb I've never seen that before. I'll just send you here the AndroidManifest.xml text. You'll then have to copy/past it into a text editor, and rename the file "AndroidManifest.xml".
Edit #1: I can't even decode the APK, can you tell me what is this file and where you got it from ? The apk file size limit is 100MB , what is this file ?
Edit #2 : Usually the AndroidManifest.xml isn't encoded at all, you just have to browse the APK with a zip explorer to find this file and read it. I personally won't do that as this file is very suspicious... 1,3 Gb for an APK... Apktool doesn't recognize it... This is really weird, I recommend you just to trash it.

To decode a binary AndroidManifest.xml file you use axmldec: Android Binary XML Decoder.
