Error parsing XML: not well-formed (invalid token)

[aboodnour7]

Information

1. Apktool Version: 2.2.1
2. Operating System: Both Linux and Windows
3. APK From: Playstore (https://play.google.com/store/apps/details?id=com.musixmatch.android.lyrify&hl=en)

Steps to Reproduce

1. Download apk from (https://apkpure.com/musixmatch-lyrics-and-music/com.musixmatch.android.lyrify)
2. Decompile apk using apktool d music.apk -o output
   (You will notice non-ascii characters in decompiled files both Smali and XML files which probably the reason recompiling fails)
3. Try to recompile the output using apktool b output, it would fail leaving the following errors

Thought I had fixed this in 2.2.2, but doesn't appear to be so. I need to patch the XMLNode class.

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

[danrspencer]

Is it possible to manually work around this issue for now?

[aletorrado]

Bump! Any update on this issue? I'm dealing with special characters in classes, method names, and XML tag names!

[iBotPeaches]

@aletorrado There is no update to report. Updates to bug reports will always be made in the respective bug report, so you don't need to worry. Any related update will be posted in here.

[matthuisman]

I have struck this issue with v7.0.1 of the Netflix apk

[mohammed-ali-1]

I have also struck this issue with an app i'm currently trying to recompile

[gilbsgilbs]

FWIW, this seems to come down to a bug in libexpat which doesn't allow the proper character set for names. When a XML resources refers to proguarded names, it has good chances to crash. See libexpat/libexpat#171
