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);

我在startActivity

上收到错误

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;
    }

Answer 1

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。

文档中的小记： Note: Users need to run version 4.2.16 of the mobile YouTube app (or higher) to use the API.

编辑：这是您使用它的方式：

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 :)  
}

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

Answer 2

设备应安装最新的YouTube应用程序。

Answer 3

您是否在模拟器上运行应用程序？它可能无法在模拟器上运行，因为默认情况下未安装youtube播放器。尝试在实际设备上运行它。

Answer 4

为了在Android上使用YouTube api，您需要3个参数

1）YouTube Developer Key

2）视频ID

3）最新官方YouTube Android App（版本4.2.16）

通过查看你的日志猫，我认为其中一个缺失

Answer 5

您必须在自己的设备上安装YouTube Android应用，这对我有用！

Answer 6

我建议对@Nikola答案进行一些改进。可以显示本地化对话框getErrorDialog()来处理一些用户可恢复的错误isUserRecoverableError。例如，在“设置”中禁用YouTube应用时。

$num4 = count($_FILES['attach_doc']['name']);

    for($k = 0; $k < $num4; $k++) {

      $fname = pathinfo($_FILES['attach_doc']['name'][$k], PATHINFO_FILENAME); // Returns Filename without extention
      $exn = pathinfo($_FILES['attach_doc']['name'][$k], PATHINFO_EXTENSION); // Returns extention without Filename
      $docs = $fname.'-'.date("dmY").$k.'.'.$exn;

$intd = move_uploaded_file($_FILES["attach_doc"]["tmp_name"][$k], 'uploads/dev_req/attachment/'.$docs);


     $sql4 = mysqli_query($con, "INSERT INTO `erpdev_supporting_document` (`unique_id`, `supporting_doc`, `status`) VALUES ('$uid', '$docs', '1')");

     $msg = "<p style='color:#1578a5;'><strong>Request data has been added successfully</strong></p>";
    }
