Description

When project is built for Android, then VS closed and project moved to a different folder, the built application cannot be started anymore.
Seems like some absolute paths are used in the output.
The following list of errors appears:

From @janseris:

@v-longmin full repro video with all steps visible:
as you can see in the video, the path for the XML which are not found, is pointing to the previous location

video.repro.missing.xml.when.compiled.project.moved.MP4

I believe this issue probably happens with Xamarin.Android as well, moving the milestone on this one.

[dellis1972]

This is probably not going to be an easy fix. The Aapt2 Daemon requires full paths in order to work since it is not specific to a particular project.

So we might need to detect this in our build properties changes detection and treat a project location move like a full rebuild and clean out the entire cache and start again.

Just fyi, this also happens on the dotnet pack command.
Clean up didnt work here, but I could fix it by deleting the .vs folder.
