Error Failed to complete ResolveLibraryProjectImports task

Question

I get and am mistaken when trying to compile an Android project in VS2017 with Xamarin. I was getting a string like an invalid error, and one of the suggestions was updating all of my Xamarin.Android links. I found one that was observable for Xamarin.Core, so I installed it. Every time since then I get a permission error. I tried to remove the obj and bin directories and restart vs and my laptop.

Here is the error text

Here is the problem: System.IO.PathTooLongException: The specified path, file name, or both are too large. A fully qualified file name must be less than 260 characters, and a directory name must be less than 248 characters.

Try moving the project to another location, for example "C: /", or change the name of the project to something shorter

Answer 2

solution edits your Android project file (csproj) as shown below

Answer 3

I just answered another SO question ( fooobar.com/questions/419671 / ... ).

Its essence is that if your solution is saved in a place with a long path, this may lead to the fact that some files will have a path that exceeds the maximum for Windows (260 characters)

Try moving the solution to the root of your C or D (if you have one).

Answer 4

There was the same problem. This is how I fixed it.

• Restart Visual Studio
• Open project
• Clear solution
• Restore solution
• Close Solution
• Reopen the project

Answer 5

I got this when I added a link to Xamarin.GooglePlayServices.Ads to my project through NuGet. As soon as I did this, I got the same problem as the OP. Moving my code to the root directory of my C drive did not help either; however, at the suggestion of Alper Ebikoglu, I added ...

 <UseShortFileNames>True</UseShortFileNames> 

... to my project file in the property group for my build configurations. After reloading the project in Visual Studio, I was able to create the project.

Hope this helps!
