我使用以下代码其工作正常播放Youtube视频与自动播放和静音功能，但当它播放视频然后我的音乐应用程序停止工作。一次只有一个在工作…

    mWebView = (WebView) findViewById(R.id.web);
    String  videoURL = "https://www.youtube.com/embed/R52bof3tvZs";
    String vid = "<html><body style='"margin: 0; padding: 0'"><iframe  width='"100%'" height='"100%'" src='""+videoURL+"'" type='"text/html'" frameborder='"0'"></iframe><body><html>";
    WebChromeClient mWebChromeClient = new WebChromeClient(){
        public void onProgressChanged(WebView view, int newProgress) {
        }
    };
    mWebView.getSettings().setPluginState(WebSettings.PluginState.ON);
    mWebView.setWebChromeClient(mWebChromeClient);
    mWebView.setWebViewClient(new WebViewClient() {
        public void onPageFinished(WebView view, String url) {
            mWebView.loadUrl("javascript:(function() { document.getElementsByTagName('video')[0].play(); })()");
        }
    });
    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.getSettings().setAppCacheEnabled(true);
    mWebView.setInitialScale(1);
    mWebView.getSettings().setLoadWithOverviewMode(true);
    mWebView.getSettings().setUseWideViewPort(true);
    if (Build.VERSION.SDK_INT < 17) {
        Log.i("GPSNETWORK", "<17");
    } else {
        Log.i("GPSNETWORK", Build.VERSION.SDK_INT+">=17");
        mWebView.getSettings().setMediaPlaybackRequiresUserGesture(false);
    }
    String myUrl = "&lt;html&gt;&lt;body style='margin:0px;padding:0px;'&gt;'n" +
            "        &lt;script type='text/javascript' src='http://www.youtube.com/iframe_api'&gt;&lt;/script&gt;&lt;script type='text/javascript'&gt;'n" +
            "                var player;'n" +
            "        function onYouTubeIframeAPIReady()'n" +
            "        {player=new YT.Player('playerId',{events:{onReady:onPlayerReady}})}'n" +
            "        function onPlayerReady(event){player.mute();player.setVolume(0);player.playVideo();}'n" +
            "        &lt;/script&gt;'n" +
            "        &lt;iframe id='playerId' type='text/html' width='1280' height='720''n" +
            "        src="+videoURL+"?enablejsapi=1&amp;rel=0&amp;playsinline=1&amp;autoplay=1&amp;showinfo=0&amp;autohide=1&amp;controls=0&amp;modestbranding=1' frameborder='0'&gt;'n" +
            "        &lt;/body&gt;&lt;/html&gt;";
    mWebView.loadData(""+Html.fromHtml(myUrl), "text/html", "UTF-8");`

请帮助我，提前感谢。

经过很长一段时间后，我修复了当玩家状态准备好时标记为真，并在我执行暂停时放置(检查)标志，它可以同时运行

String myUrl = "&lt;html&gt;&lt;body style='margin:0px;padding:0px;'&gt;'n" +
            "        &lt;script type='text/javascript' src='http://www.youtube.com/iframe_api'&gt;&lt;/script&gt;&lt;script type='text/javascript'&gt;'n" +
            "                var player;'n" +
            "        function onYouTubeIframeAPIReady()'n" +
            "        {player=new YT.Player('playerId',{events:{onReady:onPlayerReady, onStateChange: onPlayerStateChange}})}'n" +
            "        var done = false;'n" +
            "        function onPlayerReady(event){player.mute();player.setVolume(0);player.playVideo();done =

' " + bool(真正的)+"'"

;} ' n";

private boolean bool(boolean b)
{
    you_tube_started = b;
    Log.e(TAG, "you_tube_started  "+you_tube_started);
    return b;
}

这里像这样使用

if (mMediaPlayer != null && isPrepared) {
                    if (mMediaPlayer.isPlaying()) {
                        Log.w(TAG, "AUDIOFOCUS_LOSS : Nothing  you_tube_started  "+you_tube_started);
                        if(!you_tube_started)
                            pausePlayer();
                        pausedDueToAudioFocusLoss = true;
                        /*mMediaPlayer.stop();
                        mMediaPlayer.reset();*/
                    }
                }
