一個過時的「Android SDK中構建工具」錯誤的Xamarin

Question

當我創建Xamarin項目，並建立Droid的它會不錯... 但是，當我使用添加控制檯例如任何NuGet包：

安裝-package Acr.UserDialogs 或安裝，包裝Rg.Plugins.Popup 這說明我這個控制檯上：

此後，我得到這個錯誤，同時建立Droid的項目：

An outdated of 'Android SDK Build-tools' is in use which this version of Android Support Library does not support. You must uninstall any 'Android SDK Build-tools' versions older than 23.0.0 from the 'Tools' section in your 'Android SDK Manager'  

但我沒有任何舊內建工具...

Answer 1

我去構建工具下SDK文件夾和我有「機器人-6」文件夾，它包含了內置的工具版本23.0.3但是因爲它的文件夾名稱，Xamarin需要的是一個老版本。

我刪除它，然後所有的事情去了吧...

因此，文件夾名稱是Xamarin重要。

Answer 2

你要打開的Android SDK管理器，檢查你所使用的工具的版本。如果您使用Visual Studio，甚至可以使用Android工具欄上的按鈕（View - Toolbars - Android）從IDE打開它。一旦打開，您將能夠看到您已安裝的Android構建工具的版本，以及它們是否與您使用的庫所需的版本相匹配。
