If the same was done to an app that happened to be live, that would be instructions for warez.
[UTIL][JUL 22, 2023] Apktool - Tool for reverse engineering apk files
- Thread starter iBotPeaches
- Start date
Decompiling and building an app with no changes creates a crash at run time. App is Chase UK, anyone know how to get it to build? I have even disabled src decompiling with argument -s and it crashes even when I also use -r to skip res decompiling. Some xml files appear out of nowhere

Not sure why you're trying to decompile/recompile a banking app but apktool obviously won't work with hardened apks.

It won't work. Signature verification would fail immediately. You would need to make a magisk module patch that passes security features that hide root and modified systems. There are already magisk modules that should work on your device.
It's not really practical:
- You'd have to redo the patch with every update. The decompiled .smali files can change significantly between releases, so it's not automatic even if you keep prior diffs.
- Older versions of banking apps can stop working in a matter of weeks, so you have to keep updating. Staying on an old version is a risky option, you can lose access anytime.
- These apps typically also have some tamper protection that would also have to be defeated, which adds to the workload.
I ran into a similar issue recently. In my case, the app was looking for test-keys in build tags (among many other things but this is where the check failed). The patterns in the "obfuscated" code were all hard-coded in one place, so it's just a matter of taking a look and making sure you don't trigger them.
Also if you reinstall the app manually, be sure to make it look as if it still came from the Play Store (pm install -i com.android.vending or equivalent). Some apps are now querying the installation source too.
Anyway, just my two cents.
Hi all.
As I'm still on Pie I've been using Substratum to theme my apps dark, whatsapp has been fine up until now. Get no layout or drawable folders and when I open attrs and styles.xml all I see now is...
...I assume they've just used whatever protection methods now to stop tinkering?

</style>...I assume they've just used whatever protection methods now to stop tinkering?
thanks for the reply. before I can get into the actual source code to patch these checks, I first have to understand why decoding without res and classes (-s - r arguments) and then building them again produces a different res folder. why doesn't it just copy the res folder like it says it does?
edit: I have realized this to do with when files in the res folder have multiple different case spellings of the name (e.g. rQN.png and RQn.png). It seems like it takes one and ignores the rest

Got folders now but most files are labelled APKTOOL_DUMMYVAL_0x7f0d0000.xml and look like...
Code:

</LinearLayout>When an application strips the human readable name of the resource - think like symbols for a shared object - what should we do?
We take the resId knowing it would be unique and prefix it with APKTOOL_DUMMYVAL. What else do you suggest?

Are you trying to theme updated Whatsapp? If so, stop. It can't be edited as they obsfucated files in new update. Known issue among the theming community .
Iam not a user, and have some concept of your issue, that appears to simply be a unique place holder. I *think* the issue some users have is with the word "DUMMY". Maybe people would be less inclined to be suspicious if its was called/prefixed with something like (fisrt idea's in my head)
- APKTOOL_UNIQUE_0x7f0d0000.xml
- APKTOOL_UNIQUEID_0x7f0d0000.xml
- APKTOOL_UNIQUE_OBJECT_0x7f0d0000.xml
- APKTOOL_IDENTIFIER_0x7f0d0000.xml
- APKTOOL_LINK_0x7f0d0000.xml
- APKTOOL_INTERNAL_0x7f0d0000.xml

Or apks with obfuscated assets.
An apktool log might help in finding what's causing your problem.
Hi. I have a very specific problem with rebuilding an app. I am modifying some ./res/layout/ files to expand the length of some text fields. Literally, the only thing I'm doing is changing android:maxLength="12" to android:maxLength="25". After I make this change, rebuild, sign and replace the apk on my phone, it acts as if the application was deleted. Logcat only tells me the application was removed.
I'm using the latest apktool (2.7.0). I have already made significant changes to other parts of the app to allow screen rotation, added extra values to a field using res/values/arrays.xml, and changed and added smali code. All of these changes resulted in a working app. It's only when I change this one attribute that the problem occurs.
Any ideas what can be causing this problem? I know it's not user error. I do the same thing each time. Build the app with apktool, sign it with platform keys, transfer it to my phone, remove old apk, set permissions 0644. This has worked every time, including on my previous builds. Reading some of the other issues, I have also replaced using the same file name, and zipaligned the apk. both of these had no effect on the apks with modified field lengths. Also, if I changed the field lengths back to original, it works again, so like I said, it's a very specific issue.

Funded by two companies at the moment, as well as launching GitHub Sponsors so yes the past few months have had more activity than past 6 years combined. So it basically means in my head - "people are paying me to keep the bug tracker triaged and work on tickets when I have free time"
I don't want to sound like I refuse to budge without funding, but it has become increasingly difficult to work on open source stuff and a few sponsorships pushed me to have some freedom for that. I blogged about this in detail here if curious.
Apktool uses Proguard solely for removing unused code. It does not leverage any of the minification or obfuscation features that Proguard offers. Its simply used to help clean dependencies of functions we don't leverage so the binary size is much much smaller.5
Okay, I believe I fixed it. I needed to enforce the tool chain preferred version through all subprojects - not just the CLI - https://github.com/iBotPeaches/Apktool/commit/f3936cbd22f931659f7bd47e5a5aaf23ea3540064
It looks like it was built on a newer JDK without enforcing a lower JDK version. I'm not sure how that is possible because I see the compatibility here.
All master builds spit out an artifact when done. Take the latest commit a few days ago - can you try the build attached to it? https://github.com/iBotPeaches/Apktool/actions/runs/61526702743
Okay thanks for catching a regression then. I guess on the movement to Kotlin DSL for Gradle - it must be ignoring my specified compatibility type.
I'll have to brainstorm on this, since not sure of my mistake yet. Will accept a PR since I'm guessing my mistake is in here somewhere - https://github.com/iBotPeaches/Apktool/blob/master/build.gradle.kts3Hey,
Just to let you know that all seems to be ok with the latest apktool recompiled from the latest source.
Thank you very much for your fast fix. Much appreciated your work. I hope you'll remain motivated to continue the work on apktool cause is a magnificent piece of work.
I would have one more question if you don't mind: what's the difference between the apktool compiled with/without proguard?
Thanks again.

Also it makes working with app easier because of project-like files structure and automation of some repetitive tasks like building apk, etc.
It is NOT intended for piracy and other non-legal uses. It could be used for localizing, adding some features or support for custom platforms and other GOOD purposes. Just try to be fair with authors of an app, that you use and probably like.
