当我创建 Xamarin 项目并构建 Droid 时，一切顺利... 但是当我使用控制台添加任何 nuget 包时，例如：

安装包 Acr.UserDialogs 或安装包 Rg.Plugins.Popup 它在控制台上显示了这个：

然后我在构建 Droid 项目时收到此错误：

An outdated of 'Android SDK Build-tools' is in use which this version of Android Support Library does not support.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'

但我没有任何旧的构建工具...

【问题讨论】：

请仔细阅读：“但我没有任何旧的构建工具...”
我正面临着确切的问题，如果你知道，请告诉我们。
@Akbari 真烦人
@Akbari 你的 Xamarin 版本是什么？ Dahanam 安全鞋
如果您的问题得到解决，请告诉我@Akbari

标签： android xamarin xamarin.forms build-tools

【解决方案1】：

我去了 SDK 文件夹下的 Build-tools，我有 "android-6" 文件夹，它包含 Build-tools 版本 23.0.3 但由于它的文件夹名称，Xamarin 认为这是一个旧版本。

我删除了它，然后一切顺利......

所以文件夹名称对 Xamarin 很重要。

【解决方案2】：

您必须打开 Android SDK Manager 并检查您使用的工具版本。如果您使用 Visual Studio，您甚至可以使用 Android 工具栏上的按钮（视图 - 工具栏 - Android）从 IDE 中打开它。打开后，您将能够看到您安装了哪些版本的 Android 构建工具，以及它们是否与您使用的库所需的相匹配。
