Questions to ask before submission

Have you tried apktool d, apktool b without changing anything? Haven't got to change anything yet.
If you are trying to install a modified apk, did you resign it? No
Are you using the latest apktool version? Yes.

I am able to decompile other APKs without errors.

It looks like this APK has been protected with Dexguard or similar to stop people from modding it.

testesleah84 commented 4 years ago

Is there a way to get around that? Or is this the end of the road?

testesleah84 commented 4 years ago

The DUMMYVAL resources and more are there to allow decode. There has been 0 success of recovering any human readable name. Android doesn't care about resource names, it cares about resource IDs. Dexguard strips the human readable name, so remaking the APK back to human readable format is nearly impossible.
