This is my config :
Mac OS with Xamarin Cycle 9 last alpha packages
Parallels with Windows 10, VS Update 3 with Xamarin Cycle 9, last SDK packages/build-tools/extras up to date

I have a project with these nuget:

I attached the deploy log. As you can see, the path2 value is null.

Comment 2 Brendan Zagaeski (Xamarin Team, assistant) 2016-12-01 00:05:39 UTC
Thanks for trying the Alpha versions of Xamarin.  This appears to match non-public Bug 48213, which is summarized as follows in the latest Cycle 9 Release Blog post [1]:

Android 7.1.1 (API 25) is not yet supported in this release and can
cause deployment errors such as "Value cannot be null. Parameter name:
path2" if it is installed. A workaround is to uninstall API 25 in the
Android SDK Manager or to disable "Project properties > Application >
Compile using Android version > Use Latest Platform" (in Visual Studio)
or "Project Options > Build > General > Use latest installed platform"
(in Xamarin Studio) if you encounter any deployment failures.

[1] https://releases.xamarin.com/alpha-preview-3-cycle-9/

Indeed the attached build log from Comment 1 shows that API 25 is in use:
> AndroidSdkPlatform=25

If you get a chance, you can check if uninstalling the API 25 SDK or changing the target compile platform does resolve the issue for you too.  Thanks!
Comment 3 teamtim 2016-12-01 08:46:32 UTC

I change the compiling version so now it's work.

But now, I have this issue : https://bugzilla.xamarin.com/show_bug.cgi?id=46561

## Status update, just for thorough bookkeeping

Based on Comment 3, I'll resolve this issue about "Value cannot be null. Parameter name: path2" as a duplicate of non-public Bug 48213.  The latest update on that non-public bug is that it is now resolved in the more recent Alpha versions of Cycle 9.
