来自 YouTube 的视频源文件使 Android Studio 中的应用程序崩溃

Question

当视频位于带有媒体控制器的原始文件夹中时，应用程序工作正常。但是，当我将来自 Youtube 视频的嵌入 src 值放入 setVideoPath paranthesis 时，应用程序崩溃了。请帮忙！

     import android.support.v7.app.AppCompatActivity;
     import android.os.Bundle;
     import android.widget.VideoView;
     import android.widget.MediaController;

public class MainActivity 扩展 AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    VideoView vid = (VideoView) findViewById(R.id.videoView);
    vid.setVideoPath("https://www.youtube.com/embed/8iPFYfXuygk");
    MediaController mediaController = new MediaController(this);
    mediaController.setAnchorView(vid);
    vid.setMediaController(mediaController);
    vid.start();
}

}
