Question

完成：您可以通过此获取完成功能onPlayerStateChange（事件）的状态，再次调用player.play（）正常工作

我需要在WEBView中播放Youtube视频，还需要播放列表。所以，我正在使用YTPlayer。


在4.3和4.4版本的播放列表工作正常但在下面的版本中只有第一个视频ID正在播放第一个视频的下一个视频ID在播放列表中无法播放


我一直在搜索我在LOGCAT中发现的一些东西：HTML5VideoViewProxy.java这个类调用了，并且在LOGCAT详细信息中提到了ENDED / PAUSE消息。


为什么4.3 / 4.4版本没有任何问题，但在这些版本下方的另一侧。


请看看这件事????

以上内容位于youtube.html文件中，并通过这种方式处理此文件

 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

对于webView的4.0,4.1,4.2是否需要任何设置???

在第一个视频完成后停止的LogCat MediaPlayer中我如何处理MediaPlayer类，因此我可以重新启动MediaPlayer

在YTPlayer完成后，下一个视频没有在Android WebView中播放？
