java - 如何使用 Android API 防止 YouTube 停止播放？

Question

据我所知，使用适用于 Android 的 YouTube API，播放器在离开 View 时会自动停止。例如，当应用程序关闭或另一个 View 位于播放器顶部时。

但我见过这个应用程序:https://play.google.com/store/apps/details?id=com.mixerbox.mixerbox似乎已经找到了解决方法。在此应用程序中，当您关闭它时，视频不会停止并继续在后台播放。

有人知道如何实现这一点吗？

Answer 1

仅播放 YouTube 视频的音频违反了YouTube API Terms of Service :

Your API Client will not, and You will not encourage or create functionality for Your users or other third parties to:

9. promote separately the audio or video components of any YouTube audiovisual content made available through the YouTube API;

出于教育目的，请查看 Services开发者指南。

A Service is an application component that can perform long-running operations in the background and does not provide a user interface. Another application component can start a service and it will continue to run in the background even if the user switches to another application. Additionally, a component can bind to a service to interact with it and even perform interprocess communication (IPC). For example, a service might handle network transactions, play music, perform file I/O, or interact with a content provider, all from the background

MixerBox您提到的应用程序很可能有一个Service，当系统执行其 Activity 的 onPause() 回调时，它将视频音频的播放委托(delegate)给该服务。这就是 MixerBox 允许您离开应用程序的方式，并且您仍然可以在此处播放视频中的音频。
