我们需要在android应用程序中播放多个视频而没有任何延迟，但youtube播放器APi的初始加载时间很高。有没有办法降低视频质量取决于设备??

Answer 1

等一下，我在API提供的文档中找到了一些东西。查看

/docs/reference/com/google/android/youtube/player/YouTubePlayer.PlaybackEventListener.html#onBuffering(boolean)

或者仅仅是YouTubePlayer.PlaybackEventListener.html#onBuffering(boolean)

似乎有你需要重写的回调。

似乎有一个PlayBackEventListener为您提供您正在寻找的onBuffering。
