完成：您可以通过此和 player.play() 再次调用获得完成功能 onPlayerStateChange(event) 的状态工作正常

我需要在 WEBView 中播放 Youtube 视频，还需要播放列表。所以，我为此使用 YTPlayer。

在 4.3 和 4.4 版本播放列表工作正常，但在以下版本中，只有第一个视频 id 在第一个视频完成后播放，播放列表中的下一个视频 id 不播放

我一直在搜索我在 LOGCAT 中找到的一些东西： HTML5VideoViewProxy.java这个类调用并得到了我在 LOGCAT 详细信息中提到的消息 ENDED / PAUSE。

为什么 4.3 / 4.4 版本没有任何问题，但在这些版本下面的另一边。

请看看这个问题？？？？

以上内容在youtube.html文件中，通过这种方式处理这个文件

 try {

        InputStream is = getAssets().open("youtube.html");
        int size = is.available();

        byte[] buffer = new byte[size];
        is.read(buffer);
        is.close();

        String str = new String(buffer);
        str = str.replace("videoId: '%@'", "videoId: '"+video_id+"'");
        str = str.replace("'playlist':'%@'", "'playlist':'"+playlist+"'");

        String mime = "text/html";
        String encoding = "utf-8";
        engine.getSettings().setJavaScriptEnabled(true); // engine is id of WEBView
        engine.loadDataWithBaseURL(null, str, mime, encoding, null);
    } catch (Exception e) {
        e.printStackTrace();
    }

First video running fine but when the first video completed. I am using loop in the YTplayer but the next video does not play automatically in 4.0,4.1,4.2 verson

In other side in Nexus 7 (4.3 and 4.4 version) next video automatically run successfully

webView 4.0、4.1、4.2 是否需要任何设置？

视频完成时编辑 logcat 输出

在第一个视频完成后 LogCat MediaPlayer 停止以及如何处理 MediaPlayer 类，所以我可以再次重新启动 MediaPlayer
