for those (like me) who have not much exp with app dev (yet):

I stumbled over this error as well and I did the zipalign part and for sure my resources.arsc was not compressed (zipalign -v shows that!). The reason for me was that I still used jarsigner from an older guide I had… so the fix was simply using apksigner instead and it worked immediately ( source )
