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.

Howdy.
I'm trying to modify a .so file (libflashplayer.so), but have run into a few problems:
I first tried editing the file after it was installed from an .apk. This appears to work at first, but the edited file is quickly replaced with the original.
I then tried editing the file in the .apk package. This causes the package to fail to install (I'm guessing because the md5 in the certificates no longer matches)
Aldo tried moving a folder with the .so files from the .apk (com.adobe.flashplayer-1 which is what is created when the .apk installs correctly) directly into /data/app-lib/.The directory was created successfully but appears to be immediately deleted.
Is there a way to accomplish what I'm trying to do? If so how?
Other possibly relevant info:
My device is rooted
I did not write the code for anything in the .apk, I got it from a link on xda (pretty dubious i know but I couldn't find another option)
I'm using cyanogenmod 10.2 (based on android 4.2 I believe).
I'm editing the file with a hex editor to change a a few characters ("AND" to "WIN")
Hello
I have an Android device based on Tegra CPU and with 5.1 Lollipop installed.
It has few own apps installed on it that basically are a custom menu and few apps that run on it.
I downloaded an update of it which contains:
boot.img, file_contexts, system.new.dat, system.patch.dat and system.transfer.list
I managed to extract the system.new.dat file to obtain a system folder which I don't know if it's only an update of the system folder on the device or the full folder instead.
Whithout root I copied the system folder out of the device with the apps that I want.
I'd like to run theese apps on another android device.
What do I need to get out of the device in order to try this apps to run?
Only the apps in system/app folder or there are also libraries that I need?
By don't know about, I copied out of the device also the lib folder.
I'd like to try on android studio the apps firstly.
Is there any way to know if an app needs libraries and which ones?
Thank you so much
Giulio

Hi, recently I've dual-booted my computer with Android & Windows 10. But the android rom has shown too much ads so I've deleted the files causing to show the ads from the "system.img" and also "ramdisk.img" (downloaded from internet) and replaced the files with the original ones. Now the ads are not showing but I had built-in root access with SupperSU which I've lost after replacing "ramdisk.img". So I've extracted the original and the downloaded "ramdisk.img" and found an "init" file which doesn't have any file extensions and the "init" file is differing in size between the original & downloaded "ramdisk.img". So I think this file may be the cause to revoke root access. So need to change the file.
Does anyone knows which type of file is the "init" file and how can I edit it?

You can't modify an APK, as it's in binary. You could remove it though - Let me know if you need help.
An APK ( read: Android Application Package ) file by nature is a ZIP file - not a binray - what can get extracted with any zip utility (e.g. 7zip), you can view all resources correctly but all java files are not correctly decompiled.
Content of an APK file looks like
You can also see the contents of an APK file within the Android device itself, which helps a lot in debugging, using
https://play.google.com/store/apps/details?id=com.dasmic.android.apkpeek
All files including the manifest of an app can be viewed and also shared using email, cloud etc., no rooting required.
