我搜索并尝试了Stack/Android文档或教程中找到的所有解决方案 你知道为什么我不能在视频视图中播放YT的视频URL吗? 在AndroidManifest文件中添加了INTERNET权限,这也是我的代码的一部分:Java MediaPlayer“无法打开”?,java,android,youtube,Java,Android,Youtube,我搜索并尝试了Stack/Android文档或教程中找到的所有解决方案 你知道为什么我不能在视频视图中播放YT的视频URL吗? 在AndroidManifest文件中添加了INTERNET权限,这也是我的代码的一部分: String url = "http://www.youtube.com/watch?v="+eventData.getYoutube_id(); final VideoView vw = views.getVideoView(R.id.vw_media);
String url = "http://www.youtube.com/watch?v="+eventData.getYoutube_id();
final VideoView vw = views.getVideoView(R.id.vw_media);
vw.setVisibility(View.VISIBLE);
try{
MediaController mc = new MediaController(context);
mc.setAnchorView(mc);
Uri video = Uri.parse(url);
vw.setMediaController(mc);
vw.setVideoURI(video);
catch (Exception e){
Log.d(TAG, e.getMessage());
}
vw.requestFocus();
vw.start();
我在应用程序中收到一条消息,说无法播放此视频
日志:
MediaPlayer:无法打开:java.io.FileNotFoundException:无内容提供程序: 根本无法解决这个问题。。
顺便说一句,Android版本是7.0在mmediplayer.setAudioStreamTypeAudioManager.STREAM_MUSIC之后添加这个
