现在我是发射器。有什么方法可以知道当前屏幕上显示了一个 pip windows？
isInPictureInPictureMode()只表示你的应用pipmode，如果有其他应用进入pip模式，则为false。
当您退出应用程序并转到 pipmode 返回启动器时，意图标志是相同的。

我检查了 pip 模式源代码，他们通过 WindowManagerService 控制了它。我不认为它可以通过应用程序级别访问。
您可以构建一个 AccessibilityService which can query the AccessibilityWindowInfos for isInPictureInPictureMode()。
Note that Google is currently (late 2017) hunting down the abuse of accessibility service feature, so be cautious. This approach will very likely count as an abuse. Use this only if you couldn't find a better solution.

请注意，这需要提示用户许可，并且用户必须明确接受无障碍服务。
