After update Xamarin in Visual Studio to 4.2 version, there is no "Export Android Package" option, instead of it there is "Archive" option, and when I use archive to create package it just create an unsigned package.Where is "Export Android Package" in new version???
This functionality has been replaced with the new "Archive" functionality.

This now closely mimics the current behavior in Xamarin Studio.
Once you sign the .apk
you will be prompted to save the .apk
to place of your choosing:
You will then be able to view previous archives.
