Brut.all of XDA has released the program APKtool which make the process of editing any APK file much easier, especially XML editing. Before you had to use a few different programs (Smali, hex editor, etc) to do the same thing. A future release is going to have the decompiler dump into an easy to import into Javabeans/Eclipse format.. so nice
Program and Usage link;
APKTool 1.2
Setup;
Before you start, download from the link above both the apktool-1.2.0.tar.bz2 and apktool-install-windows-2.2_r01-1.tar.bz2 and extract them to your windows folder.
Usage;
Decoding APKs;
Code:
apktool d <file.apk> <directory to output to>
Compiling APKs*;
Code:
apktool b <directory of decoded apk>
*The compiled apk will be saved to the sub directory "dist", which is in what ever directory you choose to compile.
Output structure;
Smali directory - The output of classes.dex, the code to the apk
Res directory - Your resources, the images and layout/structure xmls
Lib directory - Shared library files
Dist directory - The apk output of the "apktool b" command, if you didn't run it you won't have it.
Build directory - The compiled output of the "apktool b" command, like what you would see if you just extracted an apk file with 7zip. If you didn't run it you won't have it.
General info;
Once you have your edited apk from the Dist directory you'll need to sign it. I use Dave Da illest 1 of XDA's modified script for signing. Just place your apk, this should be the only apk in this folder, in the same folder that you extracted the auto-signer to and execute sign.bat. The script will output your_app_signed.apk, which is your signed and ready to load on your phone apk.
If you'd like to decompile/compile an apk file that doesn't have a classes.dex, like framework-res.apk, just place any classes.dex into the apk and it will decompile. If you don't do this apktool will through up an error. Just remember to pull the classes.dex out before you sign it.

Editing an Apk file with APKTool;
http://www.youtube.com/watch?v=XXgYVHTcl6c
Editing a Jar file with APKtool;
http://www.youtube.com/watch?v=VAekeWiqHcY
Why?;
Localization / Translation
Themeing
Adding in features or taking them out
Impressing friends and family, lol
etc..
Issues;
I noticed that while the new version 1.2 works great on the framework-res.apk file, it seems to have issues with other System/app files like Settings.apk,Phone.apk, etc. For these files use version 1.1.1.
Hopefully this is helpful, I tend to ramble.

Will do, not having a good time at the moment as I can't seem to edit launcher.apk with this tool. Not sure why. basically I decompile, edit then compile but having issues when transferring it back to the phone.
EDIT: I just get a black screen when trying the new modified .apk file.

See Attachment, I think it's this line

I think you can't install Launcher just like that, because it's system app. You should do it through update.zip file.
Try to not use apktool, but just unpack Launcher.apk, remove META-INF dir, zip it back, sign and install. If you will get similar problems, then they can't be related to apktool (because you didn't even use it), but to something else.

If I unzip it, remove META-INF dir, zip it back, sign + install and it works fine. It doesn't work when I edit 1 file by decompiling and compiling, sign, upload it fails but it also fails using APKManager.
EDIT: I have also tried using notepad++ / notepad to edit the xml both to the same issue.
Err... you know, your problem is for sure related to signing/installation and not to apktool. Key error line is here:

Could you explain, how is it possible, that you can properly sign rezipped apk, but you can't reapktoold' one? If you get signing issues, then this is totally irrelevant what apktool does. All files could be random binary strings as well cause they aren't even read.

Hey guys... really trying to theme for the first time with xml files.
I have done modifying of png which are easy, but just lenghty and detailed.
So now that Gingerbread is out, some of the items have been moved to the xml files.
indeterminate was from 4 and now down to 3. but I want to increase to 8 to mimic honeycomb. Also the progress horizontal was once a png reference file now its in the systemui.apk xml too.
Anyhow short version.... anytime i edit more then 1 line at a time after decompiling, when trying to say it will ask to save as text.
Whats the best file editor for xml? or recommendations.
I use notepad++ on windows, you can also import your decompiled apk into eclipse and use that, it'll also report any errors or mistakes you might make.
Hope this helps.
Yeah I have been using that do and any time I compile and flash it just gives me boot loop.
Question about proper importing to eclips.
Whenever I just flat out decompile ... do my modification, go to recompile, it get errors. In apktool and apkmanager.
Should I extract the resource file and class dex out and then decompile. Cus when I have the resource file in the same directory....at least last nights attempt, apktool finale didn't give me an error and compiled.
I've done a decompile just from apk and imported to eclips and when I try to run, gives error.... "no style availiable" or something like that

[Q] Is there a way to edit "styles.xml" in the values folder and recompile it?
Hello all.
Im trying to recompile the Settings.apk and I have made edits to the styles.xml file. Only problem is in the "keep" folder there is no "values" folder, and the recompiled app does not have the edits I made in stlyes.xml
Anyone know how to recompile the Settings.apk and have the "values" folder show up in the recompile "keep" folder?
Delete resources.arsc or something in the keep folder ; if your using apk manager it should tell you this already

1)
you know what? if you have just edited the *.png and *.9.png files.. then you just use Winrar or 7zip (7zip i recomend)
first decompile with apktool .. then edit the .png n .9.png and then open the apk file with 7zip n just drag the files you edited.. n you done .. now just flash the file (hope you know how to make a flashable zip , if you dont then go to the index by VBHTT in general section n search there ) but do not try to edit xml files with this method.. it may end up messing your rom..
OR
2)if you wanna edit xml file then install all resources to your computer..
lets take an example..
you wanna edit framewor-res.apk
then you will need com.htc.resources.apk(from /system/framework) n systemui.apk(from /system/app)
n then install all three of them with apktool on pc with these commands
Code:
apktool if framework-res.apk
apktool if com.htc.resources.apk
apktoo if systemui.apk
then decompile the framework-res.apk with this code
Code:
apktool d framework-res.apk framework
it will create a new folder named framework n decompile it inside it..
after done editing the xml files n pngs you can compile it with this code
Code:
apktool b framework framework-res(new).apk
now copy this new framework apk file to desktop .. rename it to framework-res n then flash it .. hope i helped.
NOTE:
do not write apktool b framework-res.apk framework
here 'b' means BUILD .. the parameters are wrong. you cant build the apk framework like this.. instead it should be like this..
apktool b framework framework-res(new).apk
here frame work is the folder that is to be built as an apk with file name framework-res(new).apk this is the thing that might be causing you error.. hope i helped

Hi mhrsolanki2020
I am agree with your tut, but one thing, are you sure we have to type " apktool If systemui.apk " to edit .xml files ?
Because when i edit .xml in systemui.apk , i always only typed "apktool if framework-res.apk " with "apktool if com.htc.resources.apk" and everything works fine .
Sorry for my english

I was just wondering if anyone with the UAMDL software has been able to decompile and recompile the framework on here yet.
I have tried with the APK multi tool and the decompile works fine but when I try to recompile it errors our right away.
Anyone have any luck with this?
If so what tool did you use?
Yes I have.

I'd like to know this as well, and how people have been successful. I haven't had any luck installing framework-res.apk or recompiling a modified app. From my understanding, it's an issue with apktool and aapt that needs to be updated.

I used the tool in my signature and you have to remove some layout paramaters in the xml files then recompile and copy the originals over to the newly compiled apk.

Making changes only to the arrays.xml file in the values folder.
Which styles should I be commenting out and then which file should I copy to the original?
I tried putting a + in front of a few lines based on the errors I was getting but that seemed to make it worse.

Did I miss something.
Made some progress and decompiling ok now on a different computer.
If I add the + before the layouts would that cause operation issues?
I would like to know too.
Still having trouble.
What did you do too decompile?
Okay I can now get it to recompile adding the +layout to the xml files that were erroring in the compile log and only other change was made was to the arrays.xml file to enable bluetooth tethering like on the GS3 did.
however when I push it to the phone and chmod and try it I get a boot loop.
Did I do something wrong?
Am I supposed to copy out the resource.asrc from the file I compiled like a zip then add it to the original that I pulled using 7zip or something?
Any input would be greatly appreciated.

Okay, so I am trying to get the navbar working on the Samsung Galaxy Note 3. Pretty much, I have a feeling that SystemUI is missing the icons for the navbar, which causes it to crash when the build.prop has the line "qemu.hw.mainkeys=0". The SystemUI has all the other files that were required for the S4 sysui mod, except for the icons. Being a noob at this, I went ahead and tried to add the icons, but my apk resulted in "System UI has stopped.".
So I decided maybe I am doing something wrong. So with Android Multitool for windows, I installed framework-res.apk, SystemUI.apk, and twframework-res.apk. Next I select the SystemUI.apk for decompiling, and decompile it. Then I simply select the decompiled directory (didn't modify anything!), and recompile it. I then open the new SystemUI.apk in 7z and add the META-INF and AndroidManifest.xml from the old SystemUI.apk. I then select the newly compiled SystemUI.apk for signing, then I sign it.
This is just decompiling, then building the same thing without modifications. SystemUI.apk before decompiling is 2.7 MB, the newly compiled one is only 2 MB! Something is missing out of the new one, but when I compare them in 7z, the only thing I can see that is different is the packed size; whereas the old one has files and folders that take up more space packed than the new one.
When I try doing this with just apktool and cmd, I get java errors like crazy, and the whole SystemUI.apk ends up only half decompiling.
Any idea what I am doing wrong?
Your best bet would be to copy the log to pastebin, and post it in the apktool support thread. Get more views there for sure. Which version of apktool are you using? Can you decompile and recompile anything? Also, if you want post your systemui up and i could see if I can get it to work, narrow it down to a problem on your end that way.

all you have to do is add a + before the @ sign in the line that is giving you errors....umm depending if it is xml errors....
