Reversing Android Apps

thanks to cktricky for pointing me to:

android-apktool

Once you've gotten it installed/unzipped its fairly easy to use. Download your .apk from the emulator.

user@dev:~/android-tutorial/android-sdk-linux_86/tools$ ./adb pull /data/app/com.joelapenna.foursquared.apk com.joelapenna.foursquared.apk 2441 KB/s (625416 bytes in 0.250s)

From there simply decode the .apk

user@dev:~/android-tutorial/reverse$ ./apktool d com.joelapenna.foursquared.apk foursquare
I: Baksmaling...

I: Loading resource table...

I: Decoding resources...

I: Loading resource table from file: /home/user/apktool/framework/1.apk

I: Copying assets and libs...


From there you should have a folder looking something like this


inside your smali folder will be all the decompiled java. have fun.

actually after i did the above, I found this which is a video covering the above and previous posts.

Found a couple of things when Android reversing that I hadn't seen mentioned before, maybe useful so I put them up: http://thomascannon.net/projects/android-reversing/

This is an interesting solution, anyway i think it's ways better to use dex2jarto create a jar file and then use a java decompilere(there are planty). You will get almost the original code. Very useful.
