Cannot Extract APK - IDEs, Libraries, & Programming Tools

First ok all, Move if not in the correct spot (Or Delete if against TOS)!
Unsure if this is possible but I'm trying to extract an APK (Not sure if I should mention the App, I Did purchase the app) to make a small change to the code. I Can get to a certain point of extraction and then it stops. The files I need to edit are extracteded however so I can change what I need to, but as files are missing, when I recompile the app does not launch.
Any thoughts? Suggestions?
I've tried both APK Studio & APKTools

[Q] How to edit theme images and not have phone hang on boot?

I've figured out all apk files are really just zip files, but why am I not able to unzip the framework-res.apk file, edit the images within, then save it again without causing my phone to hang on boot?
Is there some step I am missing? I've tried rezipping with normal compression, store only, and only photoshopping and resaving a single image within the apk and still it fails.
How are images edited and updated? What am I missing?
I use apkmanager myself for most theming. You might look into it

An apk is a zip, but it's a *signed* zip

Here is the way I do it. I use 7zip to do this and I think it is the only program that can do it.
The way you can do it is to extract the drawable-hdpi folder within the framework-res.apk then do all your edits and save them with the exact same file names. Then you can go back into your framework-res.apk and drag and drop the drawable-hdpi folder back in and it will over write the original ones. Now just hit the Up (like to move up a directory) button until you see the message "framework-res.apk has been changed. Update it in the archive?" then click yes. Now you can put it on your phone without force closing. If you were just editing framework-res and it was not within another .zip file then you won't get that message and that is fine.
APK Manager.
You can use extract/zip (2/3) for image-only edits, but you need to decompile/compile (9/11) to mess with xml files.
Do *not* sign system apks (like framework-res.apk). Do sign other apks.
Btw, this is in the wrong forum.
(Next step: learn about the update.zip packaging script. Remember to name it something besides update.zip afterwards, because on the Fascinate we're installing everything through Clockwork, which should be the only file actually called update.zip.)

Oooh! I didn't know this app made xml's editable. That opens up a whole new set of theming fun. I can't wait to release my new theme. It should be well received (I hope)
Btw, this is in the wrong forum.

I considered putting this in Themes, but this was a theme development question, so here it ended up. If the Theme and Development forums ever hook up and have a few drinks, then spawn a sub-forum, Theme Development, I assure you it would have been a much easier decision to make
Thanks everyone for helping me out. My last time playing with a phone is an old WinMo 5 device. Anroid seems limiting in it's own ways (no dedicated theme files (can't update without losing the apk theme), but much better for customizing for a 'look' of the OS.

Need a means to compile apks

OK seeing as my computer currently doesn't work, I need to know if there is an app for my phone that will at least edit the contents of an apk, if not compile one. Anyone?
Also, if this is in the wrong section, feel free to move it, mods.

apk's are just renamed zip files.
If so, then is there an app that will directly edit zip files? And do they need to be set to store compression level? If so, is there an app that does so?

yes, set to store...all you have to do is long-press the file and select rename...same to change it back afterward. I don't know about what app will allow you to set to store, but there are a TON of free zip apps. Check the market
I need to edit them though, and if I extract it edit it then zip it with an app, it's not set to store.

Root explorer can open xml files in apps but I don't think it can edit them.
After modding the contents of a non-system apk file i believe you'll have to re-sign the apk. I dont know of any way to do that on your phone, i am admittedly not an expert though. Ive modded icons and such for apps and the only way I could find out how to get them installed was to re-sign them on my PC and push back to the phone.

Yeah signapktic can sign on the phone, all I need is an app that either will, zip things set to store like in sundae or one that will directly modify the contents of the zip.

The files inside apk is I think encrypted. normal text viewers (ex. notepad) cant see it. and the resource files (styles strings colours ) are archived again. Btw it would be great if we have an app to disassemble them within 4n. Coz copying apk from and to to computer is a pain

Well making it a zip on my phone didn't screw anything up. I can still browse normally. What I need is a means to edit a zip without compressing it, like you have to for bootanimatjons and everything else.
From my X10a running WB CM 6.1.3 V053
I would suggest having a look through the market....download every free app you can find and see if any help. There are so many out there that I have no idea which would work for exactly what you will want it to do. Really, trial and error is the best way, sometimes lol
eclipse
I'm not sure I understand correctly, some previously mentioned are right on track.
Contents of an APK file are as normal zip files, extract the APK with winrar, 7zip or similar program.. make modifications and re-zip it and change the file name.
Important process called "Zip Align" optimizes the file for the APK format and helps to optimize and align the archive for memory mapping I/O ensuring the payload is delivered correctly, for more info - mmap
If you would like to reverse an APK file, I choose to use APKTOOL a Google hosted project and complete with it's own reverse engineering syntax called "baksmali" - This wraps AAPT - Android Asset Packaging Tool part of the android SDK - need this installed.
An issue exists with obfuscated Java classes. Meaning source code has been scrambled (obfuscation algorithm) enabling it be understood by a compiler but no longer is human readable. Another issue is Signing the APK file as most installers are to authenticate the issuing publisher.
To build an APK anyone only need's have the Eclipse IDE and Android SDK installed and you can do this without even having an Android device by using the emulator to build and test your application.
Happy play!
EDIT: Apk edit and Apk tool are both able to help in this situation also.

Rename an apk so you can install it twice

I've been looking for a way to do this for the past couple days with no luck. Just to get any suspicions out of the way, I am not using this to steal someone else's work, it's for a workaround for a game that I'm trying to accomplish using two save files. I've tried going into the android manifest, editing the package name, and then resigning the apk with no luck (i just get parsing errors when I try to install). Is there any way that this can be done? or am I missing something?
It is not a simple matter.
APKs are managed by package name, not by file name, but you can't simply change the package name in the manifest of a compiled APK.
Even assuming you manage to do it without messing up the file, which is not a simple task, there will still be code referring to the package name, so the app will crash.
To put it simply, you would be better off getting your device rooted (if you don't already have root) and playing with the application data files if you want to cheat at some game.

[GUIDE] How to easily edit/modify .apk files! (Simple, Noob Friendly)

Hey Guys an' Girls!
Anyway, so when I first learnt how to decompile, modify then recompile .apks I found it was a rather slow process and figured out a far faster way.I searched google and xda many times and couldn't find my method anywhere. So without further ado, let's go through an easy, simple, step by step guide on how to modify .apk files!
Step 1 - Getting the .apk
Firstly, of course, you will need to obtain the .apk file that you want to edit. There are two methods to do this:
a) If you have the recovery flashable zip for the rom you are currently on, simply open it up, navigate to the file you want to edit (in my case system -> app -> settings.apk) and drag the .apk file onto your desktop.
b) Using root browser or a similar app on your device, navigate to the .apk you wish to edit and copy it onto your sdcard. Then connect to your computer and copy the file from your phone to the computer.
Step 2 - Editing/Modifying your .apk
Now is the important part. Install Winrar by clicking the link. http://www.win-rar.com/download.html?&L=0 Then open the .apk by right clicking the file -> open with -> WinRar. Now you can look around the .apk file. Find a file inside the .apk you wish to edit. (In my case I'm going to navigate to res -> mipmap-hdpi -> ic_launcher_settings.png). Just drag the file from the .apk and edit to your liking.
NOTE: It is recommended never to completely take everything out of the .apk and then put it all back in. Just do one file at a time.
Then when your finished, select the old file in the .apk and press the delete button. Now drag in the new edited file into where you found it. Easy!
Step 3 - Putting the new .apk back where it belongs
Now of course, your going to have to put it back on your device to see the changes in effect, there's no point having it on your computer! There are two ways to go about this:
a) Open up your rom and navigate to the place where you took your .apk file from. Click on the old .apk file and press the delete button. Now drag your new edited .apk file into the zip. Then connect your device to your computer and drag the rom onto the sdcard and flash it via recovery. Now reboot the system and see your change/s in effect!
b) Copy your new .apk file from your computer to your device. Then, using Root browser or a similar app, navigate to the old .apk file and look at the permisions. (eg. RW--r--) Now delete the old file and replace with the new, but make sure to set the permissions the same as they were before. Now Simply reboot and see your change/s in effect!
NOTE: For some .apk files (eg. Framework-res.apk) there might be missing folders inside the .apk (eg. Values).
Just hit the thanks button, he doesn't bite your finger!
This is an easy way to edit the images only(icons,wallpaper,etc),not XML files,Smali's and such.I do this using the kitchen,easy way if you theme alot.

You don't have to use this guide just for images. That was just the example. You can use it for almost any file inside an .apk. I was just saying that SOME folders aren't there.

Yes, depending on what tool you use to decompile the apk files it may or may not decrypt them. I use apktool and it decrypts them just fine.
I think this method is no longer working for 4.3+

Thnax for great guide but,my gopro app has a update and I have changed the icon on it but the app store dosent show me the update button. How to fix so I can update?
What do I need to change in an app to substitute it for another app?
OK so I've installed a new ROM and it comes with a kernel setting app preinstalled. This app has been integrated into the system settings portion of the ROM. I want to replace this kernel settings app with one of my choice but I want to be able to integrate it into the system settings like the original app is. I tried disguising the new app by changing the name of the app and .apk files but that didn't work. Closest I got was being able to convert my app to system app but even though I changed the name, the app, when installed goes back to it's original name. Or what permissions or files do I need to change to allow the integration of my app into the settings interface. Thanks ahead of time, it's appreciated.

Tweak theme without computer

I don't spend lots of time at the computer, so I like to find ways to do as much as possible on the phone. One thing I've found is that every theme I try has at least one element I wish I could change, as much as I like it overall. I don't know enough to make my own theme, but I found a way to change elements of the theme without using a computer. I'm sure this is not news to many of you, but I figured there might be other non-experts like me out there who might appreciate it.
1. Download Apktool apk file below, install it, open it, {it will automatically update on the first use for some reason}, go to settings and check 'device has root', {leave other settings alone}, then close the app, reopen and grant su access.
2. Make a directory in storage somewhere called 'apktool', {or something}, and copy the following to it: /system/framework/framework-res.apk, /system/framework/SemcGenericUxpRes/SemcGenericUxpRes.apk, and whatever themes you want to mix and match.
3. Open apktool app, navigate to apktool directory, and import the framework files by tapping on each one and selecting 'import as framework'. When done, you can then tap on the theme apk files and select 'decompile all', and they will be decompiled into folders called {appname}-src. Go into the folders with a root explorer and change what you want, then go back to apktool, and tap on the folder you want and choose 'recompile'. When recompile is done you end up with an apk called '{appname}-src.apk'. Tap on that and choose 'sign'. When done you will get an apk called '{appname}-src-sign.apk, which you can install normally.
-Notes, questions-
- I'm currently using Z1c stock .236 deodexed rom. This app should work on other phones, roms, versions, etc, but I can't say for sure. What I know is that there are at least 5 versions of the app out there, {Google search for 'apktool 4.4' or '5.2', etc}, and it seems like each one works better on certain versions of Android. There are also configurable settings. If you have a different phone or rom, etc, you just have to mess around with it.
- This app should work as normal apktool for modding systemUI and framework, but I can't get it to recompile on LP, but only on Kk. Decompile works fine, but on recompile it complains about lacking resources. I don't know what file it wants. If someone can figure it out that would be great.
-If you don't know what files to change, all I can say is that I didn't either. Start with the obvious stuff, like navbar keys, and see how brave you get. Just make sure your file names are changed, since every app doesn't use the same names for the same files. As long as you work with copied files you have nothing to lose. If something is wrong with your modifications, then it won't recompile correctly, and you'll just get an error message, so you can't really install something that's going to mess up your phone.
- This also works for changing appearance of other apps, not just themes. See my recent posts in the Naked Browser thread for examples. However, sometimes it won't be able to decompile an app, and there's probably nothing you can do. I think the way apktool works is based on how the app was created. If something is not compatible, it just won't work.
- You don't have to decompile just to pull files out of an apk, but you do need an app that can do it. I use Rom Toolbox Pro. There may be free ones, {maybe Mixplorer}. I think you can just change the extension to zip and extract normally. However, some files and folders are not the same zipped in the apk as they are when decompiled.

Since sharing themes with others' work is not kosher, (http://forum.xda-developers.com/crossdevice-dev/sony/share-frankentheme-t3282360), I figured I'd add a little more here for anyone's personal use. In general, here's what I've found with these themes:
- Within each apk there is an 'assets' folder, which contains zip files. Each zip file mods a certain aspect of the ui. For example, there will be one for settings, which contains the little pictures next to each settings option, (personalization, with the little rainbow, etc). You can experiment with simply swapping these around with different themes. However, if you want to add a settings zip, for example, to a theme base that does not already have a settings zip in it, you have to mod the main android manifest file in the top level of the apk. If you want to see how it needs to be modded, look at one that has it already. It's pretty obvious, since it's the same entry for each zip, but with the corresponding zip name. You can also extract these zips and replace files in them and rezip. Keep in mind, though, that there are some things that aren't that simple and just won't work.
- There are some things that are coded in, and can't be changed, (as far as I can figure out), like accent color. It seems like accent color just comes with the 'android' zip, and there's nothing you can do about it. As a workaround, you can find an 'android' zip with a color you like, and change out the other files from the zip you wish you could change the accent on. Again, sometimes it just won't work and you won't know why.
- Some themes don't follow this pattern at all. I haven't learned much about them yet.
Screenshots show examples I've used...
