编译应用程序时出现错误inflanting

Question

我正在尝试创建应用程序以从ip摄像头传输实时视频。我用这个教程做：click 但是当我尝试启动应用程序，我有这样的例外：

Android.Views.InflateException：二进制XML文件行＃1：二进制XML文件行＃1：错误充气类com.camera.simplemjpeg.MjpegView

我试图解决这个问题，但我真的不知道如何解决它.. 我的代码：

MainActivity.cs：

那么，确保在该jar文件上的构建操作在“Embeddedjar”上设置。如果您还没有安装JDK 1.8，请安装它。这帮助我解决了这个错误。不幸的是，我仍然遇到播放流的问题。也许你会有更好的运气.-。
