Xamarin.Android error/warning ANDAS0000

Issue

This message indicates that the Android apksigner command line tool used by Xamarin.Android reported an error or warning.

Errors reported by apksigner and other Android command line tooling are outside of Xamarin.Android's control, so a general error code of ANDAS0000 is used reporting the exact message.

Solution

To learn more about apksigner and its usage, see the Android documentation here.
