Hi all i have a problem in modifying apk file
first in the previous versions of the application i was able to decompile the apk using apktool modifying the smail and recompile and sign the apk
but in the new version after installing the apk an error appears that unfortunately ..... has stopped
I've also tried to decompile the apk and recompile it and signing it without any modification and the same error appears
i hope to find the solution from you guys
" I've posted this question in {Ask Any Question} topic and nobody answered me"
thanks

Hello,
I'm trying to hack an apk.
My first step was to use apk multi tool, and to just decompile and recompile it.
This is what i've done:
decompiling
recompiling (without any mod)
signing
No error appears during those steps.
But this new apk won't install on my phone !
If I check difference between the two apk:
all xml files are differents
.RSA and .SF have not the same name
classes.dex, resources.arsc and manifest.mf are differents
I don't understand those difference. can somebody help me to understand that and how to recomile a proper version ?
PS: This app is a french app that shows speed cameras on the road. However this app is now only showing a big zone and not the exact location for france. But it stills show precise location for other countries, so obfuscation is done at the apk level, and I already found where it is in the code, so i'd like to bypass it and recompile a "special' version
Thanx
Just a few quick questions. Is you phone set to install from sources than Droid market? You do know the newly compiled and signed project will be located in the "place_package _here_ for_Modding" folder and is named "Signed(yourappnamehere).apk?

Hi,
yes, i took the newly compiled apk in this directory, and yes my phone is set accept unknown sources.
When i install the apk, i first have the
- liste of phones serviesc that will be used
- then the install progress bar
- then the message "application not installed"
I guess there is some kind of protection in the sources...
I also noticed that the two apk - original, and resigned one - don't have same size.
The only difference is actually in the META-INF directory : the .RSA and the .SF files.
In the original application they are:
- IFOX_.RSA
- IFOX_.SF
But when recompiling, those files are:
- CERT.RSA
- CERT.SF
I'm shure the problem comes from here, but i'm too noob to analyse that...
So my proble can be sum-up by:
Why the recompilation doesn not give me the same RSA and SF file ??
Beware there are some modifications that you cant do on decs, expecially the packagename.
also beware to disable the "non-market" tag on the phone.
Yes, but for the moment i didn't make any modification:
Just decompiling, recompiling and resigning.
Maybe you want to tell that the apk name must stay the same ? (sorry my english is not perfect )
GOT IT WORKED !!!
You must first uninstall the previous application !
I was trying to install my new one over the old one, but the signatures are not the same !!!
Thanx everybody, and hope this will help somebody !
APK edit error 103
Ok im having a similar issue.
I know the file size is mismatched but ive never had this issue
as a test i only modded 1 thing but 4 files
changed a link in an html / changed an image and its name and the html included the link to the new name
when this failed i changed the manifest and the .sf to match the change i made with name but not the sha :"no clue here"
Tried...
APK multi tool ... and 7zip to make the mods
Tried... Bothsigned and unsigned.
Tried copying the sig from old apk to new with names corrected "notsha" fail still
Tried....
Origional APK installs no issue
Uninstall orig apk rebooted
Allow out side apps yes and no.both
using file manager explorer and root browser and es file manager
Copying directly to /system/app fail
copying to data/data/app/copy fail " yes it wont even copy to there"
Tried.. Multiple phones
I then tried a hex editor on the apk. And after changes install still fail.
I modded several other apk's even my framework but this is the first app that ha given me so many issues

I tried apk multitool certify thing
i tried copying the certs from old to new apk
i tried modding the cert to correct names
So maybe im mentally challenged but i just cant figure this one out

Edit .
I attached a zip with original and modified apk's
All i want to do is simple html edits xml link edits and img changes since mostly the app is a series of pages.
Trying to modify contacts.apk to make the dialer multi-dpi compatible. Did that and it works.
My issue is recompiling the apk. Everytime I recompile the apk with apktool it looses over a megabyte in size. In my case went from 4.49MB to 3.19MB after rebuilding. Only file modified was dialer_app.xml and it's size stayed about the same.
I've brought framework-res.apk and twframework.apk into apktool. After copying the resulting contacts.apk back to the device it is not recognized.
I've also tried copying the META-INF directory from the original apk over to the new one. Still no luck. I'm new to this and if anyone has some help for me it would be greatly appreciated!
Did you sign your new apk after recompiling it ?
Do you have classes.dex and resources.arsc files in your new apk ?
since its a system apk I've read it shouldn't be signed. Only thing I did was copy the META-INF folder to the new apk. In the new apk I do see classes.dex and resources.arsc. All the files appear to be there but the apk has shrunken in size.
I'm guessing I'm missing something simple here. But I'm new to this. Been at it for a few hours haven't had any luck.
I am new in development field. I have two questions 1. Is there same meaning for building and recompiling using apk tool? 2. I know framework-res.apk is needed for apktool d com, but where and the what is the use of twframework.apk file. Please explain anyone .
Recompiled apks will be quite a bit smaller as they will have more compression applied, this is normal, just be careful as if the tool compresses it to much you will get fc's. But it should work fine.

Read the apktool website for info about framework files, as far as which one to use, if you are decompiling a la2 or la4 base use a kl2 or kk5 framework without jkays built in as the laX frameworks are kinda buggy.

OK so i want to decompile and compile settings apk, i tried apkmanager and different versions of apktool but for me all give out errors. The problem is that even if
i don't modify the settings.apk it still can't compile it... Sometimes it will decompile sometimes it won't but no matter what i can't compile it
I also searched for 5-6 hours on this but i couldn't get apkmanager to compile .... all it dit was to change the error type...
Any way i put the log file maybe someone can give me some tips to get the apkmanager to work....
And what alternatives are for compiling settings apk ? (cause other apk files work with apktool) Are there some safe, sure-fire programs that can do the job?
use option no. 10 and put framework-res.apk to Apk manager script by dragging
Please Help

Yeah same prob
Good day,
I need help on modifying an apk, its basically a game that can be dowloaded on playstore. I read alot in the forum and I saw this APK tool reverse engineering an app.
apktool. I already ask a question but maybe it's better to create a new thread that I can monitor..
Now. what I achieved now is that I can decompile the apk, edit some things like splash.png, values on strings.xml and few line on androidmanifest.xml. I tried to recompile it and I have done it with no problem. Now i have the modified apk. I signed it using apk signer and followed all the procedure with no error. I copied it to my phone and test run it but sadly it says "App not installed". I also tried using zip signer from playstore and got the same result.. I dont know where am I messing it. Please help thanks.
There is Windows app called Virtuos Ten Studio, designed to do exactly that - it works pretty well and makes the whole process much easier (no need to use cmd line at all if I remember correctly).
