[iBotPeaches]

apktool 2.4.1 error and this tool really needs to improve.

You know its open source and free right? You are welcome to contribute.

[theamanrawat]

Yes I know but can you tell me why this issue is occurring??

[Ticklefish]

I tried your file, installing AOSP framework-res.apk, and using aapt2 to get this:

(java -Xmx1024m -jar user_files\APKTOOL\apktool_2.4.1.jar d --force-manifest --only-main-classes -f -p _WorkArea1\Frameworks _WorkArea1_in\es-file-explorer-4-2-1-9.apk -o _WorkArea1_working\es-file-explorer-4-2-1-9.apk)

This issue with the dollar character in the filename is due to aapt2 and can be fixed but I can recompile without using aapt2 instead, giving me this:

(java -jar user_files\APKTOOL\apktool_2.4.1.jar b --copy-original --force-all -p _WorkArea1\Frameworks _WorkArea1_working\es-file-explorer-4-2-1-9.apk -o _WorkArea1_out\es-file-explorer-4-2-1-9.apk)

The file was recompiled without any problem.

How you installed framework-res.apk I can see in command that You used the same apk as a framework it it true?

(java -jar user_files\APKTOOL\apktool_2.4.1.jar b --copy-original --force-all -p _WorkArea1\Frameworks _WorkArea1_working\es-file-explorer-4-2-1-9.apk -o _WorkArea1_out\es-file-explorer-4-2-1-9.apk)

[Ticklefish]

I installed framework-res.apk from Android 10 AOSP.

[theamanrawat]

can you please tell me in detail that how you installed framework-res.apk from android 10 AOSP.

Like you used apktool command to install framework-res.apk but I want to know that how did you get the framework-res.apk.?

[Ticklefish]

AOSP_10_framework-res.zip

I got it from a build of stock AOSP that was shared on xda a little while ago. And I've attached it to this post for you.

[theamanrawat]

Thanks a lot for solving my issue.

[Ticklefish]

That's not a problem at all. :)

[theamanrawat]

Hi @Ticklefish I want to ask one more query regarding reverse engineering that I want to inject my own app activity in es file explorer but unable to do that.

[Ticklefish]

What sort of activity are you trying to inject?

[theamanrawat]

I actually injection metasploit payload.

Intriguing.

I can't help with that, sorry. It's not something I know much about. Best of luck!

could you please tell me why I can't able to decompile this app using apktool

https://apkpure.com/helo-discover-share-communicate/app.buzz.share

[Ticklefish]

This appears to be a different issue to the one at the top of this thread..

The APK can't be decompiled because of the way it's constructed - there is a chunk type that isn't what it should be.

To decompile this, you'll need to speak to the developer and ask for their advice.

Hey people,

The issue is not reproduced with the steps in the description.

1. Apktool Version (apktool --version) - 2.4.1
2. Operating System - Windows
3. APK From (Playstore, ROM, Other) - https://es-file-explorer.en.uptodown.com/android/download

See my log:

This open issue really misled me cause I wasted a lot time with a bit older apktool thinking the issue is still not fixed.

Best Regards
Alex

[iBotPeaches]

Not replicating the issue here, maybe it was the newer version of ES File Explorer.

Closing.
