Youtube Api Crashed，YouTubeService 泄露 IntentReceiver

Question

我已经使用 YoutubeApi 构建了一个原生 android 应用程序。 有时当我从另一个活动回退到该活动时 使用 youtubePlayer 片段 (YouTubePlayerSupportFragment) 它会崩溃并显示以下消息：

我听说我可能需要添加 unregisterReciver(Broadcast Reciver)， 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 将在其 onDestroyView() 方法被调用时释放。因此，无论何时重新创建与此片段关联的活动，您都必须重新调用 initialize(String, YouTubePlayer.OnInitializedListener)，即使通过设置 setRetainInstance(boolean)，在重新创建活动时保留片段实例。"

添加这一行有帮助：

        frag.setRetainInstance(true);

frag 是我用于 api 的 youtube 片段。
