我只是尝试将youtube嵌入视频的iframe标签加载到网络视图中，但是该视频甚至无法加载缩略图。我尝试了Internet上可用的大多数解决方案，但无法解决问题。几个月前，它工作正常，但突然我发现webview甚至没有显示视频缩略图。我还尝试只加载youtube URL（https://www.youtube.com），但是又失败了，其他URL很好。
我尝试了以下解决方案：
youtubeWebView.setWebViewClient(new WebViewClient());
youtubeWebView.setWebChromeClient(new WebChromeClient());
WebSettings webSettings = youtubeWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setDomStorageEnabled(true);
android:hardwareAccelerated="true" on application Tag
这是互联网上大多数可用的解决方案。
这是我的功能，负责在网络视图上呈现视频。 youtubeWebView已经初始化，并且mediaTrailerUrl的格式为https://www.youtube.com/embed/RiANSSgCuJk
private void prepareYouTubeFrame（String mediaTrailerUrl）{
mediaTrailerUrl = mediaTrailerUrl + "?mode=opaque&rel=0&autohide=1&showinfo=0&wmode=transparent";
String frameVideo = "<!DOCTYPE HTML> <html><body style=\"margin:0 0 0 0; padding:0 0 0 0;\"> <iframe width=\"100%\" height=\"200%\" src=\"" + mediaTrailerUrl + "\" frameborder=\"0\" ></iframe> </body> </html> ";
youtubeWebView.setWebViewClient(new WebViewClient());
youtubeWebView.setWebChromeClient(new WebChromeClient());
WebSettings webSettings = youtubeWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setDomStorageEnabled(true);
webSettings.setPluginState(WebSettings.PluginState.ON);
youtubeWebView.setBackgroundColor(Color.TRANSPARENT);
youtubeWebView.loadData(frameVideo, "text/html", "UTF-8");
}
我想要在android webview上播放youtube嵌入视频的frame标签。 Log cat会显示这种类型的消息：
