问题 How to do I check when a YouTube video has finished playing in the official YouTube Android app? In the LogCat I see things such as: VideoStage: MEDIA_PLAYING_VIDEO. Is there any way to detect when this finishes? 回答1: You could use MediaPlayer. It has an isPlaying method to check if music/videos are currently playing. Just set a Boolean to true while it's playing and check the isPlaying method against that Boolean to see if it changed from True to False . Otherwise Youtube (or google) may

问题 When the Android browser opens a media file it can play, the built-in (stagefright?) media player opens up to stream it. A title for this media is displayed on the player dialog, based on the URL. The URL in this case was http://10.0.37.195/waug_mp3_128k . The media player simply uses the last part of the path as its title. Is it possible to change the displayed title?

Eg. if it is currently paused at 1:30, then on click of a button, it goes to the previous bookmark, i.e. 00:45. I thought using MediaPlayer.seekTo() will help me achieve this.
