I'm getting the same error with https://play.google.com/store/apps/details?id=at.rsg.pfp , if more samples are useful for this bug.

Looks like this is a duplicate of https://github.com/iBotPeaches/Apktool/issues/1945

Another apk to reproduce this is https://www.apkmonk.com/download-app/com.safaricom.android.subreg/5_com.safaricom.android.subreg_2019-09-09.apk/

All the apk files which are facing this issue have something common ie. all the resource files are not in the /res dir but in the root dir and have weirdly encoded names.

Apk analyzer from Android Studio is failing to parse the AndroidManifest.xml correctly of the apk. It's reporting with unexpected tokens error.

@iBotPeaches I tried decoding the JioSaavn apk with JEB and I guess I got the issue. It uses a clever renaming for resources dirs and files with only white spaces or special characters in the name. Here are the decompilation logs.

I am having the same problem with Weapon Heroes. With 2.4.1 and a build from master.

This will be fixed in v2.5.0

@iBotPeaches Thanks but please check the apktool.yml file after decoding the JioSaavn app. It's malformed and contains some weird characters. I think those need to be sanitized first.

Decoded successfully..

Didn't have that issue. It didn't build, but I'll chuck that up to a more strict aapt2.

@iBotPeaches my bad. I was passing the wrong dir. But yes, it fails to build with both aapt1 and aapt2. Should I open another issue for that?

I would investigate those first, if those are warnings because aapt2 is more restrictive then probably not. If it appears that it should be working, then sure. We should investigate.
