在线视频无法播放

我正在按照教程在 Android 中播放视频，教程在这里 http://theandroid.in/play-online-video-example-in-android-device-with-source-code/

但是当我在模拟器上运行应用程序时，它给出了以下错误

媒体播放器错误（1、-2147483648）

请帮忙

这是我的应用程序的代码

将此添加为此处的答案，以帮助其他人解决此问题 - 我发现此错误主要仅发生在模拟器上，并且似乎在设备上运行良好。可能是模拟器设置问题，如果发现任何官方报告的问题，我将更新此线程。我只在尝试播放 wmv 等不受支持的格式时在设备上看到过这种情况。如果有人在模拟器上有此问题的链接，请添加
