我听说我可能需要添加取消注册接收者(广播接收器(， 虽然我还没有找到办法。
Youtube api 文档似乎涵盖了解决方案：https://developers.google.com/youtube/android/player/reference/com/google/android/youtube/player/YouTubePlayerFragment
"与此片段关联的YouTubePlayer将在调用其onDestroyView((方法时发布。因此，每当重新创建与此片段关联的活动时，您都必须重新调用 initialize(String， YouTubePlayer.OnInitializedListener(，即使通过设置 setRetainInstance(boolean( 在重新创建活动的过程中保留了片段实例。
添加此行有助于：
frag.setRetainInstance(true);
frag 是我用于 API 的 youtube 片段。
