这是我用来启动播放器的代码

String vid=getYoutubeVideoId(vlink);
Intent intent=YouTubeStandalonePlayer.createVideoIntent(getActivity(),DEVELOPER_KEY, vid, 0,true,false);
startActivity(intent);

我收到了错误 startActivity

这是getYoutubeVideoID()代码:

/*
     * Getting id of video from url
     */
    public static String getYoutubeVideoId(String youtubeUrl)
    {
        String video_id="";
        if (youtubeUrl != null && youtubeUrl.trim().length() > 0 && youtubeUrl.startsWith("http"))
        {

            String expression = "^.*((youtu.be"+ "\\/)" + "|(v\\/)|(\\/u\\/w\\/)|(embed\\/)|(watch\\?))\\??v?=?([^#\\&\\?]*).*"; // var regExp = /^.*((youtu.be\/)|(v\/)|(\/u\/\w\/)|(embed\/)|(watch\?))\??v?=?([^#\&\?]*).*/;
            CharSequence input = youtubeUrl;
            Pattern pattern = Pattern.compile(expression,Pattern.CASE_INSENSITIVE);
            Matcher matcher = pattern.matcher(input);
            if (matcher.matches())
            {
                String groupIndex1 = matcher.group(7);
                if(groupIndex1!=null && groupIndex1.length()==11)
                    video_id = groupIndex1;
            }
        }
        return video_id;
    }

首先检查您的设备上是否有可用的youtube服务,然后尝试启动该活动. YouTubeApiServiceUtil.isYouTubeApiServiceAvailable(mContext).另请尝试从Google Play安装youtube应用.

文档中的微小注释: Note: Users need to run version 4.2.16 of the mobile YouTube app (or higher) to use the API.

编辑:这是你如何使用它:

if(YouTubeApiServiceUtil.isYouTubeApiServiceAvailable(mContext).equals(YouTubeInitializationResult.SUCCESS)){
   //This means that your device has the Youtube API Service (the app) and you are safe to launch it. 

}else{
   // Log the outcome, take necessary measure, like playing the video in webview :)  
}

请参阅YouTubeInitializationResult此处的枚举https://developers.google.com/youtube/android/player/reference/com/google/android/youtube/player/YouTubeInitializationResult
