Decompiler

Hello, I want to decompile my framework-res apk so I can possibly add a battery that displays percentages. Is there any program out that will let me do this?

Your looking for Smali/BakSmali.
No offense intended here, but the fact that you are asking tells me that you are going to need a lot of research in doing this. It's not necessarily decompiled into the most readable source code. But it's that way with most decompiling, and you probably realize that.
Also, since we don't have source code for HoneyComb, the current Smali/Baksmali implementation doesn't work well/at all for some files.
Good Luck.

No offense taken. I am in the process of teaching myself these things so Google and xda are my best friends. Thanks for the reply

Thank you, I have previously viewed that thread. There aren't really any clear cut instructions on setting it up properly. Are you able to edit the XML files contained in the drawable folder? That is all I'm interested in. I can't seem to successfully decompile the framework-res apk. Thanks again

I will offer to help you out.
1. Install latest SDK from http://Developer.google.com & Eclipse.
2. Search for apktool and unzip files into the SDK folder under platform_a DB
3. Buddy fix apktool with attached files. You will need to rename these files to Apktool, etc..
4. Copy framework-res.apk, systemui.apk, settings.apk, and launcher2.apk from \system + copy the odex
5. Run apktool d framework-res.apk (do this for each apk)
6. Look in the Res/drawing folders for images to mod.
Now you have the .9.png files with marks & the decompiled XML for reference.
Use Photoshop to modify the files.
Use draw9patch to compile any .9.png files
This is really important. Use 7zip or any other zip app that allows you to open and view an apk as a zip without actually unzipping it. Just copy the new photo files in and add them to an update.zip (you can download this from XDA Xoom Development thread) or use a DB to push the updated files to the Xoom.
Theaming is a subject but that's the basics. I can't upload files for newapktools.zip right now but will edit this when I get home later. Alternativly, maybe someone can post the patched up Xoom compatible apktool files. They are also in XDA theaming thread if you search.

Yes I can you need Java JDK installed:
http://www.oracle.com/technetwork/java/javase/downloads/index.html
Eventually you will need Eclipse and I use Gimp because its free and doesn't break any .png files.

I use Notepad++ to edit XML

Thank you very much for that! I edited the images I want to use, I waes just trying to add the respective values into the XML. Is it possible to add a battery with 1% increments as of now?

Decompiling ICS 3.32.401.5 APK's using apktool.jar (APKMnanager) update

I have been playing arround with the issue of not being able to decompile the apks from OS 3.32 roms.
The issue seems to be when decompiling the systemui.apk you are getting the following errors:

This points to erros in Backsmaling and the backsmali files being too old. I then hunted arround and found a neat little tool to deompile apks and the jar files to make them editable. This did not work either giving me the same error. I then found an update backsmali.jar and smali.jar ver 1.3.2 from here: and it decompiled the systemui.apk perfectly.
Can we intergrate the newer versions of the smali 1.3.2 files into apk manager to decompile ICS roms? This is a bit beyond me!
Progress update:
Ok I have download the source apktool using ubuntu. The next stage is to download API15 and add it into the source then rebuild, but not sure how to do that yet. I know I have API15 on my Windows PC but dont know what files I need to update apktool to API15. Will keep working on it though!
Yep, it's a problem right now. Check out this issue:

Can I ask why you do not trust the results?
I have tried with the hacked version and so far I am now able to decompile and compile the systemui.apk with out any problems! But still got errors compiling framework-res.apk so still some issues there! All I did was modify value.xml file to enable crt animation!
Hi, for to decompile all apk must remove classes.dex from this apk and decompile with apktool1.4.2.....after compile with 1.4.3 and reinsert classes.dex into the apk
same problem with me,also looking for help.

In this way,decomplie is ok,but re-complie still has problem
I ive noticed that you cant compile with this just yet. Looks as if we are going to have to wait for a rebuilt tool!
From what I can see the current apktool.jar was built with API14. ICS 4.03 is built with API15. What we need is to have the apktool.jar updated with API5. This involves building the apktool from source which I believe is available but I dont know how to do this

where is this said hacked apktool?

I don't know either
Unfortunately I chose to learn flash ActionScript 2 years ago (it was useful at the time - I had Samsung Tocco Lite and made flash themes for it) but since moving to Android I realised flash doesn't do a lot of good when working with java so at some point I really need to learn java

I dont know what to do here, I have updated my sdk, made sure i installed theright framework. done everything from replacing the aapt file to replacing the apktool file. Its ridiculous that compiling the SystemUI.apk has to be this difficult, if it can be decompiled easily why cant the reverse be just as simple??
I cant get SystemUI.apk to compile, it starts the process then just errors out.
Has anybody found a workaround for this? Updating my SDK and aapt and apktool didn't work for me.

It looks as if we need to download the source of apktool from git. Add in API15 and the updated smali and backsmali tools, then recompile the apk tool. Unfortunitly this is a little out of my leauge.
If anybody is able to do this it would be awsome!
Out of my skill range as well

Do you think it would be possible to simply edit the pngs of systemui without decompiling and recompiling by taking out the .9 pngs to edit those with the .9 editor?

How to compile CM10 from source?

Ok bright minds I need your help. I've been told that in order to make an xml change in the contacts and phone apps that I have to make the change in source then compile the rom. In JB and ICS you can't make changes to the xml's in those apps like you can in every other app.
So can someone please tell me how to make those changes to source and then compile the rom? Once I get it compiled I won't need to do it again. It's the only part of my theme that isn't theme.

Thanks I think that's what I was looking for. All I need to do is change one line of code so that I can theme the contacts app. I have to do all that just to change that one line.
EDIT: I can't do all that. I sent h8 a pm asking if he could make the change for me next time he compiles his rom and just compile an extra one with the change but he didn't answer back. =(

Hi..
Best tool will be apktool.. on windows or on linux..
Apktool for it.. Check details on the original thread for it..
Its pretty simple..
with latest apktool you can not only decompile and recompile apks but also jar files using apktool ... by
Code:
apktool d <nameofile>
or
Code:
apktool b <nameoffile>

while porting with patchrom i get old_smali,new_smali,dst_smali_orig,dst_smali_patched:,reject.in temp folder
now i have to compare and patch smali code.now which folders i need to use to compare and patch smali files.
The easier method is compile the zip without modify the smali and fix it after if there is some error .The common error in patchrom its only the RIL
Hope porting will soon complete
