How to use Autosign with Linux ? - Android Q&A, Help & Troubleshooting

Hello,
I`m trying to edit the WhatsApp app in my android phone using Autosign ( a windows executable).
I followed all the steps until i executed the sign.bat (with Wine) and i cant keep on.
The problem is that it doesn´t recognize the other files that are needed to create the new apk.
Here you can see what appeared in the screen.
Auto-Sign Created by Dave Da illest 1 Edited to be easier to use with APK files by mixpix405 Make sure the APK you want signed is the only APK inside this folder Pulse cualquier tecla para continuar... .apk is now being signed. The signed version be named your_app_signed.apk Can't recognize 'java -jar signapk.jar testkey.x509.pem testkey.pk8 *.apk your_app_signed.apk' as an internal or external command, or batch script.
anyone knows how i can make it work ?

Just curious, why dont you use native linux tools for dis/assembling/signing etc. APKs?

Android's .so files

OK, So I've gotten to breaking down and recompiling those pesky .dex files, but I've run into a new problem.
This is a noob question, I'm sure, but .so files look like unformatted, binary files. How do I open then, edit them, etc? I need to read whats going on in my libs. :-(
Are these X11? I'm running ubuntu 10.04 x64 - so those could be difficult.
ie - unreliable 64 bit support.
$ sudo ln -s /usr/lib32/libX11.so.6 /usr/lib32/libX11.so

They're native library files, so platform specific machine code I imagine. Look for an ARM disassembler. I'm not familiar with linux internals, so don't know how you find the entry points, but it obviously will be widely documented. Is it impossible to obtain the source code? Assuming most are written in C/C++, reverse engineering from the machine code is not something I'd describe as a pleasant experience. If the source was well written assembly language & not too big, it can be almost enjoyable I guess. But then TBH walking through a randomly selected programmer's source, let alone object, files scares me, in a Tim Burton inspired bad trip kinda way. If you can find the source, it will be an order of magnitude less painful.
Try IDA Decompiler, it should disassemble all so files!
Most of the libs are open source in the aosp. Some are proprietary blobs with the only solution to them being reverse engineering.
.so disassembly
i know how to disassemble it
you will need orion's easy apk disassembler and apk manager
i've tested it once and it worked, but there´s a problem, i dont know how to re-assemble
1- rename the file .so to .apk like "libtestlib.so" to "libtestlib.apk"
2- put in the folder "place-apk-here-for-modding" of apk manager
3- open script.bat (or something like this) from Apk manager
4- use extract apk option
in the beggining my images inside the lib was corrupted so i used step 5 to fix
5- use option optimise images inside to fix images
6- go to project folder and copy classes.dex file to the root of easy apk disassembler's folder
7- open EasyApkDisassembler.EN.bat and use the "DISASSEMBLY a classes.dex with smali" option
8- give a name to the folder (like "libtestlib")
9- it will create a folder (like "out_libtestlib") with the disassembled files

I've tried to open libsurfaceflinger.so from my device with 7zip, and it worked too
thats it
@gkillershots
not working
i renamed .so to .apk and used extract option but getted error :
Processing archive: C:\APKMultiTools\place-apk-here-for-modding\libnative-lib.apk

[Q] How to implement Admob into App Inventor Apps

Hello All
I have tried using App2Market to let the Eclipse read the app but it can't :|
is there any way to make this done ?
Thanks and Best Regards..
Any Ideas ?
Use APKTOOL to Decompile App Inventor App
first put a copy of your ai app in the windows directory
Once you Download and extract the APKTOOL to your (i use windows) directory, open command prompt.
cd to the directory you extracted the apktool into. cd\Windows)
enter this line of command:
apktool d -s c:\windows\YOURAPPNAME.apk
it will take a sec to decompile the app. but once it does, your app will show up as a folder in windows dir.
from here, you can go into eclipse and create new android project from existing source. and navigate to the extracted version of your app. you will find the APK tool on here if you search for it. and the instructions there are better.

[TOOL][DEV][LINUX ONLY] Fast java src decompiler

Hello !!!
I'm not a real developper but I manage to make a little tool FOR DEVS to accelerate java src decompile
I don't know if it can be useful, but I wanted to share it ...
I don't really create something, all the tools already exist, you know them all :
JD-GUI : Java decompiler
Dex2jar : useful tool to transform .dex in readable .jar to get java src
Why did I made this ?
I searched how to get java src, useful to build apk or even compile sources, but only found manual way.
Ok decompiling one or 2 files is not a big deal ... but when you need to decompile a whole rom ......
What can this tool do ?
getting the java src from an apk and / or a .jar (framework.jar for eg) dex2jar and jd-gui already allow it
can decompile several files (.jar and or .apk)
rename each file to is native name
How to use it ?
This tool only works on Linux
Download attached zip or here
Unzip the file in home folder The folder must be in home and musn't be renamed or it won't work properly
launch the dex.sh (double click in graphic or use ./dex.sh commande in terminal)
Follow the instructions
.classes files need to be associated to JD-GUI use this programm. If you don't know if they already are or not, don't worry let the command do it ...
For more information, I included lines to make .jar files open by JD-GUI.
If you don't need / want these files to be associated after you use this tool type in terminal
PHP:
cd ~/.gnome2/nautilus-scripts
sudo rm open-in-jd-gui.sh
This tool is not perfect ... firstly I made it for me ....but finally wanted to share it ...
if you like it just tell me and use it ... if you don't .... ok just tell me why I would improve it ...
Huge thanks to :
JD-GUI Developpers : http://java.decompiler.free.fr/?q=jdgui
DEX2JAR Developpers : http://code.google.com/p/dex2jar/
tommytomatoe : for his wonderful Android Utility and for the command lines that helped me more than a lot !!! :good:

APKTool Decompiling Java Problem

I am having problems getting my APKTools to decompile an APK (I'm new to this). Here is my process:
- Downloaded the 3 apktool files and pasted them in the folder C:\APKTool
- Put framework-res.apk in the same folder
-Opened a command prompt in the folder C:\APKTool (Held shift and right clicked on folder)
- Typed "apktool if framework-res.apk"
I get the error:
'java' is not recognized as an internal or external command, operable program or batch file.
- I have the android SDK installed (everything in 32 bit, my eclipse works)
- I have installed the Java JDK in the same folder as the SDK
- Java Runtime environment 7 is installed in C:\Program Files (x86)\Java\jre7
I'm pretty stuck at this point. If it helps my operating system is windows 8 pro 64bit. Any ideas would be greatly appreciated.
Im stupid
Sorry I just reinstalled JRE and it worked fine. Wish I could go back in time before I posted this

[Q] Apktool problem

I want to decompile some system apps and I can't even get apktool to work. I installed java jre and jdk both and I get the following error in cmd:
Java is not recognized as an internal or external command
So I set my environmental system variables for Java on my windows xp computer as shown below:
View attachment 2825945
But I still get the same error as before! I need someone to please help me figure this out before I get even more frustrated!
Make sure you have installed apktool correctly
Windows:
Download The Following From Here
apktool1.5.2.tar.bz2
apktool-install-windows-r05-ibot.tar.bz2
Unzip both files with winrar and put the contents (there should be 3 files) in C:\Windows
if you have java jdk installed you should be able to type apktool and hit enter at the command prompt and if installed it will give you all the options for apkool
Linux:
Download apktool-install-linux-* file
Download apktool-* file
Unpack both to /usr/local/bin directory (you must have root permissions)
Mac OS X:
Download apktool-install-macos-* file
Download apktool-* file
Unpack both to /usr/local/bin directory (you must have root permissions)
did everything still not working
I Followed this guide here which is very similiar: http://androidforums.com/esteem-all-things-root/520917-guide-how-properly-decompile-recompile-apks-apktool.html
I stopped at installing framework because CMD would not let me be able to do so!
Any other advice?
I really need to get this working!
Thanks for your help!
