Question

我正在尝试构建mondroid-sample https://github.com/xamarin/monodroid-samples/tree/master/MapsAndLocationDemo。

每当我启动应用程序时，我在输出窗口中出现以下错误：

[STDOUT] "C:\Dev\Playground\monodroid-samples\MapsAndLocationDemo\MapsAndLocationDemo.csproj" (SignAndroidPackage target) (1) ->

我检查了以下内容：

SDK Manager中安装的Google API
SDK管理器中安装的SDK Plattform
我正在使用的AVD，定位到GoogleAPIs
我以管理员身份运行Visual Studio
我可以成功构建一个Hello World示例

由于我是Mono和Android开发的新手，我确信我错过了一些明显的东西，所以请耐心等待。

看看你的照片，并且你从未提及改变它，我打赌你的项目的目标是2.2。

在MonoDevelop中，转到Project - ＆gt;选项 - ＆gt;构建 - ＆gt;一般，看看Target框架。默认设置是针对Android 2.2（Froyo），看起来您想要定位4.0或4.0.3。

将此更改为4.0或4.0.3，您应该好好去。
