沙马林。在本地Android设备上部署解决方案时,Android不支持运行以前的版本

xamarin.android xamarin visual-studio android

我的Xamarin PCL项目运行良好,因为我下载了Android SDK Platform 27并更新了所有NuGet软件包。

当尝试将解决方案部署到我的设备(运行Android 7.1)时,我得到以下输出错误:

生成失败:Xamarin。Android不支持运行以前的版本。请确保在运行或调试它。

调试此项目时生成日志:

我已将目标框架设置为 Android 8.1 最新平台。
目标Android版本: 使用SDK版本编译 。
最低Android版本: Android 4.4 。

以下是我已经安装的Android SDK列表:

我曾尝试将目标平台更改为7.1,但情况变得更糟

我在使用任何AVD模拟器时都会遇到同样的错误。

谁能解释一下我为什么会出现这个错误,以及我能做些什么来解决它。

当我过去遇到这种情况时,问题是我正在部署到一个已经安装了该应用程序版本的设备上,有两种可能性:

安装的版本的版本代码大于我尝试部署的版本代码,和/或
安装的版本是我的应用程序的Play Store版本,Xamarin无法覆盖该版本。Android工具。

您还可以在错误列表中看到错误:

ADB0030: Mono.AndroidTools.RequiresUninstallException: The installed package is incompatible. Please manually uninstall and try again.

在我的案例中,解决方案是以下一种或两种:

通过UI或使用命令提示符下的ADB从我的设备卸载应用程序(例如,ADB卸载 包装名称 ),然后重试我的部署。
更改包清单(Project.Android>Properties>Android manifest)以使其版本代码高于当前安装的版本代码,然后重试我的部署。
