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.
Created attachment 18729 [details]
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 :
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.
Indeed the attached build log from Comment 1 shows that API 25 is in use:
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!
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.
