title: VSTS Xamarin.Android build error
body: <p>I want to setup the build of my Xamarin.Android app in VSTS. 
  I received the following error in the Build.Xamarin.Android step: Error : This project references NuGet package(s) that are missing on this computer. Use NuGet Package Restore to download them.  For more information, see <a href="http://go.microsoft.com/fwlink/?LinkID=322105" rel="nofollow noreferrer">http://go.microsoft.com/fwlink/?LinkID=322105</a>. The missing file is ....\packages\Xamarin.Android.Support.Animated.Vector.Drawable.25.4.0.2\build\MonoAndroid70\Xamarin.Android.Support.Animated.Vector.Drawable.targets</p>
  
  <p>I followed the steps as described on the page described in this link: <a href="https://docs.microsoft.com/nl-nl/vsts/build-release/apps/mobile/xamarin?tabs=vsts" rel="nofollow noreferrer">https://docs.microsoft.com/nl-nl/vsts/build-release/apps/mobile/xamarin?tabs=vsts</a></p>
  
  <p>What am I doing wrong?</p>
