如何播放来自；CastVideos android示例应用程序“；在手机上，当没有wifi/chromecast在电视上显示它们时？

我已经安装了CastVideos android示例应用程序，如官方网站所述，并使用（感谢@entertailion）

当通过wifi将视频播放到chromecast时，该示例非常有效

但是，当我在家以外通过3G使用手机应用程序时，我还需要该手机应用程序在手机上显示视频，而无需在电视上播放此功能在以前的版本中可用。自从项目移动到Android Studio后，它就不起作用了：单击项目时，会出现等待图标，视频不会显示在手机中，几秒钟后，您会被重定向到主播放列表

以下是来自logcat的日志：

有什么建议或想法吗？

好的，支持Chromecast的应用程序有一个总体设计原则，其中铸造依赖于两个或多个屏幕之间的协调；发送方用户界面和接收方用户界面-它们必须协同工作。如果您想推荐一项新功能，您可能需要查看此内容以了解更多信息，或者向Google Cast团队咨询。

即使是在播放时也不需要WiFi。因此，首先回答您的问题：只要您可以访问互联网，无论是通过WiFi还是数据连接，您都可以在本地播放内容。事实上，我刚刚尝试了最新版本的CastVideos android，以确保我们没有破坏任何东西，并且它在没有WiFi的情况下工作正常

此外，您甚至不需要WiFi就可以成功地向播送设备进行播送；只要为cast设备启用来宾模式，您就可以保持数据连接，并查找和cast到此类cast设备

如果您在关闭WiFi时遇到本地播放问题，我建议您首先尝试一下android应用程序，然后看看如果没有WiFi连接，您在应用程序中所做的不同之处
