If I have a *.apk that I download, is there anyway to backup/extract it?
The apk is really just a ZIP file. Try renaming the file to whatever.apk.zip and open using your favorite ZIP utility. You should be able to view all the contents. Resources (such as images) can be extracted. The java code is compiled into a .dex file so you can't view the raw code, but there are utilities (like this one) to decompile it: http://dedexer.sourceforge.net/

Right but how do I find the *.apk if I am downloading it off of the market?
apps are located in data/app/
There are also various apps in the market that will backup apps.
I use appmonster incedently.
7zip can extract and view contents of an apk without renaming.
backup and reinstalling apps....
view the first link in my signature.
I used MyBackup Pro to do a backup of my apps onto the sd card, then I used ASTRO file manager to navigate to /sdcard/rerware/MyBackup/AllAppsBackups where I found the file LastBackupApps.zip. I then used androzip or something similar to unzip that file and it contained the apk for every one of the apps I backed up.

I have a zip file with .apk.p files in it which are exracted with package_extract_file in the updater script. Is there a way to manually extract these, since renaming to .zip doesn't help if I open them with any unzipper program?
Thanks

I believe the files you are referring to - the files ending in ".p" - are "patch" files. They only appear in the OTA download .zip file, and they are worthless to you. They are not complete files, but just enough data to patch the corresponding 1.5 app .apk so that it turns into the 2.1 version.
If you want the complete .apk files which they correspond to, just download the Leak-V3 .zip file, extract the "system.img" file, and then unpack that file using the "unyaffs" utility (search for it, you'll find it at code.Google.com).

Thanks for the info. I thought I can update the apk files manually, because from recovery it doesn't work (it is a rooted image, so signature not accepted) and there are some fixes in the new update that I wanted to give a chance.

apk download
did you search for the apk online?
Hey everyone,
My stock rom on my phone has issues with MVNO's (mobile virtual network operator). Basically this means that my data connection only works when Roaming. This is a know issue that has already been fixed on several roms (but not on mine).
To fix this I would like to modify the source of the framework.jar file (`/system/framework/framework.jar`), more specific the file : `/com/android/internal/telephony/gsm/GsmServiceStateTracker.java`
To start I will list the steps I have take to show you where I'm stuck at the momoment:
- I have fully deodexed my stock rom, both the JAR files and the APK files in both /system/framework/ and /system/app
- I have downloaded the deodexed framework.jar file and extracted the classes.dex file from it
- I have decompiled the classes.dex file using baksmali to end up with several *.class files
- I have converted these *.class files to a .jar file using dex2jar
- I have unpacked opened this jar file using jdqui to end up with several *.java files
This is where I'm stuck, I need to figure out how to edit the java file I want and end up with a working framework.jar again that I can upload to my phone.
Am I doing this the wrong way? Any other way to resolve my issue? I hope to get some help from people who have experience in doing this...
Any help would be appreciated!
Bump, anyone?
Hi,
I spent 1 month coding an android app, and then I lost the source code in an hdd crash. Well, those things sux, but hopefully I managed to find an old apk build of this app. I was able to recover part of the source code by extracting the classes.dex file, decrypting it with dex2jar, and then opening the decrypted file with java decompiler (jd-gui.exe)... I remained amazed when I saw that my source code was so easy to found...
Now I wonder, why people use smali to reverse apk files instead of dex2jar+jd-gui ??
No one ??
After a week i finally managed to build a ROM from source. I have in my /out/target/product/angler folder several files incl. the system.img, boot.img etc. etc (see attachments)
But from i have heard i could edit some of those files to build a new ROM from the files which are in that directory. In the early days you had a file there with a tree format of which apps are installed. Editing that file by removing the apps you didn't want anymore resulted in a ROM without those apps. But with the new structure i cant figure out where i need to do that.
Also if someone knows how i can compile from the source in that directory, that would be great. If i would do it with lunch && make it start over again from the original source.
Nobody can help me with this? or am i in the wrong section?
Good evening folks,
I just grabbed the stock ROM of my phone (Lenovo A6000plus lollipop) and started tweaking in it. Now I have to change the files located inside framework.jar which is in the system folder. I tried dex decompiler and apk tool for grabbing the source from the jar. But I failed to repack them again into a framework.jar file. I found the same source code in the source.google.com's git repo and I downloaded it. Now how can I create the framework.jar file from the source code itself?
The documentation of AOSP is little hard to understand for a newbie like me. Can anyone properly guide me for the same?
