[Android Software Development] timkre:
Been using apktool here for a bit. It has decompiled the APK fine but when I go to build it I get these errors below. I have tried to build it without any changes and it still gives these errors. Any ideas to try?

I: Using Apktool 2.7.0
I: Checking whether sources has changed...
I: Checking whether resources has changed...
