"LinkAssemblies"链接任务意外失败 [英] The "LinkAssemblies" task failed unexpectedly

问题描述

当我们尝试在发布模式下构建xamarin表单项目时，出现错误:

When we are trying to build a xamarin forms project in release mode, we are getting the error:

C:\Program Files (x86)\MSBuild\Xamarin\Android\Xamarin.Android.Common.targets(5,5): Error MSB4018: The "LinkAssemblies" task failed unexpectedly.
Xamarin.Android.XamarinAndroidException: error XA2006: Reference to metadata item 'System.Void Android.Widget.AbsListView::SetSelectionFromTop(System.Int32,System.Int32)' (defined in 'Xamarin.Forms.Platform.Android, Version=1.3.3.0, Culture=neutral, PublicKeyToken=null') from 'Xamarin.Forms.Platform.Android, Version=1.3.3.0, Culture=neutral, PublicKeyToken=null' could not be resolved. ---> Mono.Cecil.ResolutionException: Failed to resolve System.Void Android.Widget.AbsListView::SetSelectionFromTop(System.Int32,System.Int32)

我们如何解决这个问题?我们已尝试再次清洁和建造.甚至关闭xamarin Studio并重新启动它.似乎没有任何作用.

How can we resolve this? We have tried cleaning and building again. Even closing xamarin studio and restarting it. Nothing seems to work.

我们正在使用xamarin表格和xamarin表格实验室的最新版本.我们正在使用的最低android API级别为17.我什至尝试了最低sdk版本20.

We are on the latest release of xamarin forms and xamarin forms labs. The minimum android API level we are using is 17. I even tried minimum sdk version 20.

推荐答案

显然，这是一个已知问题:Xamarin Forms需要TargetAndroidVersion为21(在配置GUI中，标题为使用Android版本进行编译:")

Apparently, this is a known issue: Xamarin Forms needs the TargetAndroidVersion to be 21. (In the config GUI, this is entitled "Compile using Android version:")
