Android 4.1 and Encrypted APKs?

Hi All,
Forgive me if this has been asked - searching XDA results in hundreds of spurious hit since the search tool does not appear to honor quotes in a search term (i.e., "encrypted apk"). My apologies for the choice of forums. I was not allowed to ask in the Android forums. Sorry about the perverted reference below. I'm not allowed to add references, either.
Android 4.1 allows encryption of an APK (see "App Encryption" at H T T P developer-dot-android-dot-com-slash-about-slash-versions-slash-jelly-bean-dot-html). What tools are folks using to decrypt the APK and get it ready for something like APKTOOL or Dex2Jar?

Is there anyway to get this moved to an Android developers forum? Thats where it belongs.

I would also be interested in this.

wtf with this?

You can view or decrypt the XML files of an Android APKfile with apktool.
Just copy the APK file also in that directory and run the following command in your command prompt:
Code:
apktool d HelloWorld.apk ./HelloWorld,
This will create and directory "HelloWorld"in your current directory. Inside it you can find the AndroidManifest.xmlfile in decrypted form and you can also find other XMLfiles inside the "HelloWorld/res/layout" directory.
Here HelloWorld.apk is yourAndroidAPKfile.
See the below screen shot for more information:

apktool development was abandoned some time ago. The last release built and offered for download is from December 2011 (https://code.google.com/p/android-apktool/downloads/list). I seriously doubt it can do anything with an Encrypted APK (a featured added in August 2012 with Jelly Bean).
apktools or smali/baksmali is broken with respect to debug information. apktools and smali debugging: https://code.google.com/p/android-apktool/issues/detail?id=339. smali/baksmali debug issue (I should have filed it as a bug report): https://code.google.com/p/smali/issues/detail?id=139. I know there is another apktool by ibotpeaches, but its broken too: https://code.google.com/p/smali/issues/detail?id=139.

Agreed. That link is a decent place to start reading up on them. It's an interesting idea, I'm curious to see how encrypted APK distribution pans out....

This is interesting

BackTrack5 on Android

Greetings,
I'm the ScriptBasic open source project manager which is an embeddable traditional Basic scripting API. We recently ported ScriptBasic to Android Linux. The goal was to use SL4A (JSON RPC interface to Android SDK) for local and remote scripting of mobile devices. Along the way I found C4droid (gcc/g++ & SDL plugins) and start playing with the JNI Android app glue API. I have a attached a small example of a native Android Linux SDL cube that is rotated via the touch screen. (enable off market apps)
I was also able to get the BackTrack5 ARM version image to run on my Samsung Galaxy Tab 2 10.1 as a chroot image. Works really well. (see examples screenshots on the SB forum)

If you mean the BackTrack image then use the Linux Loader app off Play.
If you mean why am I introducing myself here and am I asking a question? As a new user of this forum, this seems to be the only board I'm able to post to.

a) Where is the question in your post?
b) If your post is the answer, then what is the question?
c) If you're trying to promote a product then there are appropriate places for it
d) If you're trying to provide a tutorial then there are appropriate places for it

Hey there.
It's been a while since this thread was created, but I will still appriciate any response.
Why would I have to log-in? And where can I register?
I would also like to know how I can install Ruby on my device. Or how to make sure I have a rucy installed.
thanks for helpers

Hi, this is just an app that let's you browse and edit the RubyGems repository website, that's why you have to login. If you're interested in running Ruby in your device, I suggest you to take a look at this StackOverflow question, which contains the answer to your questions.

First of all, thanks a lot for directing me there, I couldn't find it myself.
Someone suggested there to root device and use apt-get. I already have my device rooted, but I don't know where I can use Linux commands such as apt-get on my android device (Galaxy S4 GT-I9515).
Another person suggested using Ruboto IRB, but I have no idea what that is nor how can I get it. I would like an explanation here as well (if you could of course )
Another question, when I use cSploit it tells me that there's a ruby updrade avaible and asks me if I want to install it. I infer that I already have Ruby if it asks me to UPDATE it (the app works fine btw), but I'm not sure.

To execute the Linux commands you need to install a terminal emulator via the Play Store, where you can also download Ruboto.

Ok cool. So you're telling me that installing a terminal emulator will actually prompt linux commands to my device? Like, it's not just a simulation?
Also, I would be happy if you could explain me what Ruboto does or how it works.
BTW Thanks again for replying, I really appriciate your will to help

[PLUGIN][GEANY] Edify Syntax Highlighter

Hi,
Yesterday, an article featured the XDA Portal, talking about a new "code editor" for the Edify language. I wasn't much interested in it, because:
1. Windows, duh!
2. Porting ROMs (which I seldom do, though), or editing updater script, I use Linux.
3. Why a new editor, when language support can be added easily to *most* of the editors? This limits user functionality, the way user had been interacting with software, and would be missing out high on features
So, I decided to add edify syntax highlighting support to the popular text editor, Geany (yes, I don't use Gedit, and hate it. Period.).
Here's how you'd go about doing this one
All changes are perfectly revertible, so, you won't have to risk reinstalling Geany :fingers-crossed:
First, copy your filetype_extensions.conf to your home folder using the following command:
Code:
cp /usr/share/geany/filetype_extensions.conf ~/.config/geany/
Open it up, and add the following line, (below "Docbook=*.docbook;" preferably, to maintain alphabetical order):
Code:
Edify=*updater-script*;
Download the following file: https://raw.github.com/thewisenerd/edify_geany/master/filedefs/filetypes.Edify.conf
And place it within your ~/.config/geany/filedefs/ folder.
Hopefully, those are all the changes that need to be done
Close Geany, and open up any updater-script file, and hopefully, you should have syntax highlighting :laugh:

Hi,
I just wanted to let you know the link for the Edify.config:
https://raw.github.com/vineethraj49/...pes.Edify.conf
seems to be dead. If you use:
https://github.com/v-superuser/edify_geany
and download as a .zip. Unzip and open the "edify_geany-master" folder.
Copy the "filetype_extensions.conf" and replace the file with the same name in the ".config/geany/" .
Next go back into the "edify_geany-master" folder and go into the "filedefs". Copy the "filetypes.Edify.conf" and pate it into ".config/geany/filedefs".
Open up Geany and go to "Tools". Hit the "Reload Configuration"
Now you are ready to go.

[app] (BETA!!) GIMP 2.10 for Windows on ARM32

EVERYTHING works. It's not the fastest, but literally everything seems to work. I've not encountered a crash and I've:
Drawn using the touch screen and mouse
Exported, saved, and loaded images/projects
And played with some layers
If you want to TRY this build, you can get it on my website. Be aware that it is HUGE, and I would HEAVILY recommend extracting it on your desktop and putting it on a flash drive.

Hello,
when I:
1. downloaded "fontconfig_2.8.0-2_win32.zip" from here:
https://download.gnome.org/binaries/win32/dependencies/fontconfig_2.8.0-2_win32.zip
2. erased "Blank Section" (lines 77-142) from fonts.conf,
3. stored fonts.conf in C:\Users\Vertex\AppData\Roaming\fonts
4. set system env variables:
set "FC_CONFIG_DIR=C:\Users\Vertex\AppData\Roaming\fonts"
set "FONTCONFIG_PATH=C:\Users\Vertex\AppData\Roaming\fonts"
set "FONTCONFIG_FILE=C:\Users\Vertex\AppData\Roaming\fonts\fonts.conf"
5. and run gimp-console-2.10.exe then it crashes.
It seems, that you probably didn't port libfontconfig-1.dll to win32 arm32?
Anyway apart from that, it works great. <3

Ah, it crashed because you tried loading a x86_32 DLL on ARM32. I'll look into it before I release another version.

Thanks. I didn't use DLL from the ZIP of course. I am not THAT stupid. LOL (I checked the DLL header with the FileInfo TotalCommander plugin and found, that DLL is win32 x32 as expected.) I only used fonts.conf TXT file from archive, because I had no idea, how to write it myself. It seems, that your GIMP win32 arm32 uses a deprecated version of "fontconfig", which doesn't support "blank_characters". So I had to delete them from the config file.
If you will release something new, it would be nice, if it would be an incremental update of only modified files. Because... "Size matters.", she said.

Also, the frylock_k19 avatar should be something like this: (Beardless it looks better IMHO.)
