这就是我认为构建日志中最相关的部分，尤其是......

error 1: System.NullReferenceException: Object reference not set to an instance of an object [C:\dotnetdev\MapDroid\MapDroid.csproj]

任何想法为什么会这样？

如果我只是运行构建，它会成功完成，但设备的打包错误......

使用Mono for Android

我还更新了包含完整的构建输出 - ＆gt; http://pastie.org/2044724

如果您使用的是免费版MonoDroid，您将无法从VS内部直接打包，签名和部署到设备。我猜最后一行包含错误的来源。否则，我看到构建引擎找不到Newtonsoft.Json.Silverlight。如果应用程序在模拟器上运行，则可以确认第一个问题的性质。

Android Packaging Failed，NullReferenceException
