Monodroid：无法找到库'com.google.android.maps'

Question

我试图构建mondroid样本https://github.com/xamarin/monodroid-samples/tree/master/MapsAndLocationDemo。

每当我启动应用程序，我得到在输出窗口中出现以下错误：

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

我检查以下内容：

• 安装在SDK管理器中
• SDK Plattform谷歌的API安装在SDK Manager中
• 我正在使用的AVD，面向GoogleAPI
• 我在运行Visual Studio作为管理员
• 我能成功打造一个Hello World例子

由于我是新来的单声道和Android开发我敢肯定，我失去了一些东西明显，所以请忍受着我。

看着你的照片，你永远不会提及改变它，我打赌你的项目是针对2.2。

在MonoDevelop中，转到Project - > Options - > Build - > General，并查看Target框架。默认情况下是针对Android 2.2（Froyo），它看起来像你想要4.0或4.0.3。

更改为4.0或4.0.3，你应该很好去。
