APKTool 2.2.2 - ClassCastException ResColorValue -> ResAttr
https://github.com/iBotPeaches/Apktool/issues/1060
It is almost the same issue with above.
Apktook tried to cast ResStringValue to ResAttr and it got an exception.
Only this time it is ResColorValue.
I personally modified the source as above and rebuilt the apktool, and it decompiled the apk without a problem.
I'd like to report here just in case it is a bug.
