Decompiling 2.2 files

Hello,
I am trying to edit settings.apk and some of the library files such as libskia.so for the new firmware in order to localize them. apktool isn't succeeding decoding the settings.apk file for 2.2 even though it was fine with 2.1 firmware. Does anyone know how I can decode the 2.2 files by using windows or cygwin? Thanks...

Do you have add Froyo's framework-res to the apktool?
apktools if system/framework/framework-res.apk

I did that but I still get errors such as:
Code:
W: Could not decode attr value, using undecoded value instead: ns=android, name=
textColorHint, value=0x02050001
Can't find framework resources for package of id: 2. You must install proper fra
mework files, see project website for more info.
Here is another question, how can I find samsung galaxy s 2.2 resources? I believe that's what I am missing to get it working. I think it might be a file like this com.samsung.resources.apk or similar.
EDIT: I managed to decode settings.apk successfully by adding twframework-res.apk to apktool. Now I just need to figure out how to edit libskia.so for 2.2.

Have you edited it in firmware 2.1?

Nearly impossible: it's native code, you know. Even worst: ARMs aren't so popular as PC, so there aren't too many ARM disassemblers/decompilers for them.
But I think it's just a image processing library, so... what to localize in it?

it has been done using linux. however, I am trying to use cygwin to do it but I can't seem to have the dpkg command installed in cygwin.

I am trying to add another language to 2.2. We managed to add it to 2.1 but 2.2 seems to use different encryption method which we haven't managed to successfully decode.

Encryption? It's a library file, like .dll on Windows. It's not encrypted, it's just compiled, like any .dll, .exe, etc. on your PC.
Did you succeed in "decrypting" libskia.so from 2.1?

Encryption might not be the correct word. When you "compile" these files, sometimes there are headers associated with them, without them, it would be very difficult to "decompile" them in order to edit it.

Ok, but Skia is an open source project, it's a part of AOSP Of course Samsung may modified something in it, but I doubt it.
EDIT:
And still it's illogical to me, that there is something to localize in image processing library.

I am trying to localize it to arabic, if you know the language you would know that its letters are connected in certain situations. Currently, these files do not connect them correctly and even more, it inverts the letter positions. In order to fix this issue, these library files have to be modified. This has been done in 2.1 and I heard someone did it for Nexus1 2.2. We are trying to get a hold of him to understand how did he modify them in 2.2.

Here is something i just noticed.
Even though I have successfully decoded and built Settings.apk using pktool. I have notice a difference in the size of the file (the newer file is much smaller). So I tried to decode and build the same exact file without any modifications and it still does the same thing (original Settings.apk is 3.4MB while the rebuilt unmodified file is 2.1MB)
Using winrar to check the new file I have noticed missing files namely the META-INF folder. Is this normal with apktool?
I used the following to decode and build the file
> apktool d settings.apk
> apktool b settings settings.apk
There are no errors in decoding or building the file.
EDIT: Nevermind, I forgot to sign the file which corresponds to the same missing files.

Ye,you have to sign the file by yourself,and with samsung's private key to works with other samsung's files

[Q] How to edit framework-res.apk?

I'm trying to edit framework-res.apk so I can theme my rom. Are these the correct steps?
pull framework-res.apk from my phone
decompile the apk
make the changes
rebuild the apk
sign
zipalign
push apk back to device
I'm not too sure on this method as after I pushed back my modified apk, I get a load of force close errors
Any advice would be welcome

don't sign and don't zipalign and all are fine

I tried without sign and zipalign but the rom wouldnt boot. If I sign, I get force close errors
Does the rom need to be deoxed?

How is your process to decompile and recompile what tools do you use

Is this an ODEXed ROM or a deOXEDed ROM? You can't mix and match. If you're not ODEXing any APKs after you've modified them then you need to make sure all APKs are deOXEDed.

It is a stock rom but there is no framework-res.odex does that mean it doesn't need deodexing even though there are odex files for every other apk in my system folder?

Nice app but this theme also needs .xml changes which this app doesnt support

ok, i put him a note in his thread about the xml changing issue, we will see what hes answer will be...
edit:
also this software could do the trick: http://android.modaco.com/content/t-mobile-pulse-pulse-modaco-com/302404/ande-android-design-editor/

I've been playing around a little more today and it seems the issue is that no tool can rebuild the xml files correctly, they seem to be compressed/encoded.
Has anyone been able to edit an xml file in framework-res.apk and have the phone read it properly?

Refer to my signature. Apk manager.
Edit : just read ur op.
Never sign the system apk's. Simply keep the original signatures intact and after recompiling them, re-include them.
So here are the rules u must follow :
If u've modified the manifest.xml, u must stop core, push the apk, start core or push the apk while in recovery.
If u've modified anything else, a simple push / reboot will do the trick.
Note, u cannot flash a modified system apk the first time (as in on a clean boot), u must flash the original rom, let it build the dex's and then flash ur modified apk.

Hi, I am already using apk manager but the xml files it creates do not seem to work.
To prove this, I have done a test. See the attached xml files,
original_stat_sys_battery.xml was extracted from the original framework-res.apk
I then used apk manager to decompile and then recompile the same apk without making any changes.
recompiled_stat_sys_battery.xml is this recompiled file
I then opened up both files and they look different to me

That shouldn't concern u. Apktool's method of rebuilding the apk/arsc file is slightly different than how android originally builds an apk. What should concern u is if the apk simply works. Now when u decompile the apk, can u check the log to see if it reports of any missing resources, if it doesn't ur fine. So decompile the apk, make ur changes, recompile the apk, move the original meta-inf folder into ur new apk and push it to ur phone following the guidelines in my previous post. if it causes problems, post ur log and i'll take a look.

Ok this time I have added meta-inf to the new apk, pushed it to my phone and the phone hangs on boot.
Here is my log

Code:

Now seems u modified the androidmanifest.xml ? If u didn't then heres my recommendation, copy over the original androidmanifest.xml from the original apk.

framwork-res.apk modifying

Hi,
i'am searching for a guide how to manipulate correctly the framework-res.apk.
All ways i have tested fails.
I would modify some symbols in Notification bar (battery 1%) but all Time the my Phone run into bootloop or all Application Crashes after Startup.
I've tryed Apk Manager 4.9 / and Manualy with apktool.
Help plz .....

what i did :
1-extract apk (i use 7zip/WinRAR)
2-edit/replace image file(s)
3-repack with zero compression level ('store' level)
4-sign the apk
5-replace file using apk or create flashable recovery zip.
regards.

signing the framework-res.apk will not work.. will make the device go into bootloop
what you need is extract the framework-res.apk using apktool and edit the things you want and then compile it again using apktool .... now open the original framework-res.apk and replace the file resources.arsc with the edited compiled one..
this way you will retain the signature of the original framework-res.apk

But when i add some new Files and Edit some XML the Sign will be Corrupted ?

no it won't...
You need to do two copies.. the original file and the moded one...
1. make a backup of the original file
2. extract the original file using apktool
3. edit and modify anything you like
4. compile the edited file
5. rename the compiled file to framework-res.zip and take the modified resources.arsc
6. using winrar or 7zip open (to view not extract) the backed up framework-res.apk
7. place the moded resources.arsc into the backed up framework-res.apk
by doing this you retain the original signature of the backed up file and not breaking it..

Thx, will test it ;-)

The right approach always depends, what you want to change. There is no need to decompile, if you only change a few standard png. If you change xml in values folder like color, styles or arrays, you can certainly not delete resources.arsc - resources have nothing to do with the signature anyway. So if you want to play safe, you should insert the original Meta-Inf (signature) and Android Manifest after compile. It is also recommended to zipalign the final apk in order to reduce RAM usage.

thanks he_stheone64 for the clarification.. i reached that conclusion based on my own research on the net and yeah i used to change the XML files to add language support and that the only way that worked with me..

And be sure to have a working and up-to-date sdk before trying to use apktool...
First, using a old sdk release i got a partially working result (few graphics bugs and strange reboots), then with a badly updated sdk on top off the old i got apktool making many errors. Finally, re-installing the last sdk from start i got apktool and my resulting apk working correctly.

Decompile and recompile framework leads to bootloop

Hi all,
Trying to mod the framework for the first time.
I have no problem replacing the png. But when i try to modify the xml, i get bootloop.
I used the apk manager (4.9) to decompile the apk, then edit one xml before i recompile. I did notice that the recompiled apk is at least 2MB smaller than the original.
Am i missing a step here?

Hi
yap ,,,the generated apk is unsigned...and no sign for system apk..so you have to copy by drag & drop the following files from the unsigned apk onto the original apk via WinRar and choosing ZIP archive format, NORMAL compression method.
- resources.arsc file
- res folder
- classes.dex file if exisit in the non-system apks
hope that help
good luck

Ah,
I was thinking this as a possible workaround so it looks like it is thr solution?
Just a confirmation, if i change the battery_charging.xml, then i should compile, then extract out the battery_charging.xml from the recompiled framework-res.apk and insert into the original, signed framework-res.apk?
Sent from my GT-P1000 using XDA Premium App

I tried taking the compiled xml ( that defines the animation of battery charging icon on the status bar), put into the original framework-res.apk, and end up with non existent icon for the battery charging. Everything else remains working though.
What could have gone wrong?

[Q] Editing framework-res.apk

Hey can someone give me some quick tips on how to edit it?
I edited SystemUI.apk just fine but no matter what I do to framework-res, it won't let me replace the files (I'm only replacing pngs in drawable-mdpi folder)

What error are you getting? Also, install framework with apktool
POTATO!!!!

I think he's talking about drag and drop png file ) If it's true, the solution for him is learning how to decompile apk. Becoz most of png in systemUI is png, not too many 9.png files so it's easy to replace without decompiling

I can't recompile because apktool always crashes when trying to recompile XML files. I'm using the AceCream framework apk instead of the stock rom one...
