我已经从https://developers.google.com/cast/docs/android_sender中导入了chromecast的示例应用程序，但问题发生在castcastellibrary -android-master和VideoBrowserActivity中。
我还导入了以下库android-support-v7-appcompat,android-support-v7-mediafrouter,Google-play-services_lib:
在为videoBrowserActivity设置了所有库后，我得到了这个错误:
CastCompanionLibrary-android-master] Found 2 versions of android-support-v7-mediarouter.jar in the dependency list,

我不知道我哪里出了问题，请告诉我怎么解决这个问题。
这意味着在构建路径中有两个android-support-v7-mediarouter.jar jar文件。因此，解决方案是从CastCompanionLibrary-android-master库或从android-support-v7-mediarouter库的lib文件夹中删除android-support-v7-mediarouter.jar。我通常从库中删除.jar文件，并将其保留在我的libs文件夹中。只保留一个版本的.jar。然后，如果需要，您需要修复构建路径。执行项目->右键单击->属性->java构建路径。在命令和导出选项卡中勾选所有.jar。
你应该从你自己的项目中删除这三个库，因为CCL已经包含了它们;只要导入CCL，你就会在这方面做得很好;看看使用CCL的CastVideos-android
