问题
Since 1 week I discovered Xamarin framework, and my job is to make Android app work. iOS app has been already launched before.
I had to deal first with some NuGet Packages dependencies, but now the only exception I get is :

I saw many posts here and it seems to be an icon problem, but i've checked all resource definitions in the project, resource names, and everything seems to be fine.
Is it possible that this problem is caused by bad References (Like Xamarin Forms, or Iconize) ? Or this can be only because of missing resources ?
I've already clean my solution updated or downgraded my packages but nothing work..
I must also indicate that I use F# instead of C# to develop. And my views are made with XAML.
回答1:
Finally found what is the problem.
First, I must set for all my resources files 'AndroidResource' in Build Action field (See in properties when you select a resource)
Second, I must not use other characters as A to Z, 0 to 9, and '_' to name my resources.
回答2:
This is what I did to resolve issue -
- I was missing "Xamarin.Android.Support.Animated.Vector.Drawable" NuGet package so I included it in my android project.For me correct version was 23.3.0 but it may be diffrent in your case.
- Deleted obj and bin folder for my android project.
- Restarted visual studio.
- Rebuild
