Steps to Reproduce

1. apktool d Insta_v8.95.apk

APK

https://www.mediafire.com/file/3wpcdvuw8pfrw60/Insta_v8.95.apk/file

[iBotPeaches]

Confirmed. Marking as bug.

[karimbenammar]

Could this be related to this issue because of the app namespace?

[jsteave]

I can confirm this Extra is still not working

[ghyath5]

Still the same issue

[mxsleo]

Comfirmed on some MiuiCamera mods (stock can be easily decompliled, but, for example, Leica mod unpacking ends in the same error)

[iBotPeaches]

Took a look at this. Looks like we regressed specific handling of string-arrays way back when this was merged - https://github.com/iBotPeaches/Apktool/pull/991/files

It isn't worth reverting something so old, so I'll have to rethink how we handle ResIntValue, ResStringValue and ResIntBasedValue

[iBotPeaches]

Putting up a PR that will close this on merge.
