When ever I try to run my project I get this error:

C:\Program Files (x86)\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(2,2): Error MSB4018: The "Aapt" task failed unexpectedly.

System.InvalidOperationException: Sequence contains no elements

   at Xamarin.Android.Tasks.BuildToolsUtils.GetBuildToolsPath(String androidSdkDirectory)

   at Microsoft.Build.BackEnd.TaskBuilder.<ExecuteInstantiatedTask>d__20.MoveNext() (MSB4018) (test)
