I upgraded to Xamarin ANdroid 6 this morning. I can no longer build our Android project from Visual Studio. I get a bunch of errors like the following:
>C:\Program Files (x86)\MSBuild\Xamarin\Android\Xamarin.Android.Analysis.targets(43,2): error MSB3733: Input file "obj\Android\Debug\android\AndroidManifest.xml" cannot be opened. Could not find a part of the path 'C:\Users\jason\Documents\code\criticalarc\Source\Libraries\Core\obj\Android\Debug\android\AndroidManifest.xml'.

I get the same error on class library projects referenced by an Android app.
Turning-off code analysis successfully works-around the issue as well as tampering with the Xamarin.Android.Analysis.targets MSBuild file to not look for the nonexistent AndroidManifest.xml file in library projects.

Moving the bug to the Xamarin Android product, as it's an issue on the build targets there.
This way the Android team can track it.
Thanks for reporting!
JonP/Dean: Please feel free to ping us if you need anything else from our side.
@Jason / @Daniel is there any chance you could provide a project which reproduces this behavior?
Also if possible please attach full diagnostic msbuild output, as this will likely provide more insight into why this error is being thrown

Simple solution that reproduces the issue
This solution reproduces the issue.
Thanks for posting the repro! You beat me to it. :)
It's a default Xamarin Android project with a default class library added.
It will immediately fail if you try to run code analysis but I've also added the following to the project file so code analysis is run on build.
I have replicated this issue :)
This problem is the Analysis Target is running but the SignAndroidPackage target has not been so the required files are not in place..
Investigating why the SignAndroidPackage target is not running.
I had success whith downgrading to Xamarin.VisualStudio_3.11.1589 to make my builds work again. Of course downgrading might break other stuff but until xamarin resolves this is one way to work around the issue.
The work around for now is to disable CodeAnalysis on the Android project
That should work until we can fix the test to actually run the SignAndroidPackage target

Fix in monodriod/master/14640e3a
This will fix this issue on Windows. For a Mac fix we still need to wait for the mono bump which includes XmlPeek which was committed in mono/master/86522f62.
@Dean Could we put up a PR for this for inclusion in mono 4.3.2? If/when that's accepted, let's bump monodroid to point to that.
I find Comment #13 and Comment #14 somewhat confusing, because mono/master/86522f62 dates to November 26, 2015, and was merged to master on December 1, 2015 (commit mono/40d516ff), and (as per `git log origin/mono-4.3.2-branch`) mono/40d516ff is already part of mono-4.3.2-branch.
The XmlPeek commit is *not* in mono-4.2.0-branch, nor in mono-4.3.1-branch or mono-4.3.0-branch.
What *system mono* is slated for Cycle 7?
As far as I know, mono-4.3.2 is the mono that will be shipping everywhere.
You didn't correctly implement XmlPeek. It's missing registration in in the appropriate .tasks files.
 Files like mcs/tools/xbuild/data/*/Microsoft.Common.tasks
A PR has been submitted for this mono/pull/2598
Fixed in mono/master/96cd1c9e9f
Cheery picked to mono/mono-4.3.2-branch/17fda960
