Xamarin LinkAssemblies建立失敗

我試圖做我的團隊服務Xamarin.Android應用程序的發佈版本，並已得到了以下錯誤：Xamarin LinkAssemblies建立失敗

The "LinkAssemblies" task failed unexpectedly. 
Java.Interop.Tools.Diagnostics.XamarinAndroidException: error XA2006: Could 
not resolve reference to 'System.Void.Android.Support.CustomTabs.CustomTabsIntent::LaunchUrl(Android.App. 
Activity,Android.Net.Uri)' (defined in assembly 
'Microsoft.Azure.Mobile.Client, Version=4.0.1.0, Culture=neutral, 
PublicKeyToken=31bf3856ad364e35') with scope 
'Xamarin.Android.Support.CustomTabs, Version=1.0.0.0, Culture=neutral, 
PublicKeyToken=null'. When the scope is different from the defining 
assembly, it usually means that the type is forwarded. --->

我可以看到，它可能涉及到包Microsoft.Azure.Mobile.Client但不知道我需要做些什麼來解決它（我對Xamarin很陌生，所以不知道該怎麼處理這些信息）。

我的minSdkVersion是21

感謝

您能否提供詳細的步驟來重現問題？ –

如果不知道設置的詳細信息，很難確定，但聽起來您可能會錯過依賴關係，[Custom Tabs]（https://www.nuget.org/packages/Xamarin.Android.Support.CustomTabs） /）包。 –

它看起來像Microsoft.Azure.Mobile.Client包的傢伙有Android.Support.CustomTabs庫的問題。請參閱github上發佈的問題：Issue 364和Issue 361。它看起來像Microsoft.Azure.Mobile.Client版本4.0.0可以針對Android.Support.CustomTabs版本25.3.1構建，但Microsoft.Azure.Mobile.Client版本4.0.1可以針對Android.Support.CustomTabs版本構建23.3.0。

在我的情況下，將nuget包Microsoft.Azure.Mobile.Client從4.0.1版降級到4.0.0版有助於構建和鏈接我的項目。
