Steps to Reproduce

1. apktool

Frameworks

If this APK is from an OEM ROM (Samsung, HTC, LG). Please attach framework files
(.apks that live in /system/framework or /system/priv-app)

AOSP_10.0_API29_framework-res.apk
http://www.mediafire.com/file/9q8ndvsupk6cs3u/AOSP_10.0_API29_framework-res.apk.apk/file

APK

Questions to ask before submission

1. Have you tried apktool d, apktool b without changing anything? Yes
2. If you are trying to install a modified apk, did you resign it? No its original one
3. Are you using the latest apktool version? Yes

This is not a bug in apktool. In fact, A3AEECD8.dex is not a standard dex file. Please see the command below.

$ file classes.dex
classes.dex: Dalvik dex file version 035
$ file assets/A3AEECD8.dex
assets/A3AEECD8.dex: data

You can use apktool d --only-main-classes to salve the problem. But if you get an error:Unrecognized option: --only-main-classes, you can see #2226

Ok ! Many thanks, i will try to decompil only main classes

[iBotPeaches]

As mentioned above. The system is looking for .dex files and not finding one, so the param - --only-main-classes will isolate the search to only dex files in the root.

Closing as not a bug.
