使用Xamarin在Android中以啟動屏幕播放視頻

Question

我正在嘗試使用Xamarin在Android中將視頻作為啟動屏幕播放。 我找到了下面的鏈接，但我正在獲取file not found exception 。 我嘗試以幾種不同的方式來走這條路，但沒有成功。

我的視頻Splash.mp4在Resources內的drawable文件夾中，而SplashActivity.cs文件在項目級別。

使用Xamarin在Android中播放視頻

 [Activity(Label = "SplashVideo", MainLauncher = true, NoHistory = true)]
public class SplashVideo : Activity, MediaPlayer.IOnPreparedListener, ISurfaceHolderCallback
{
    VideoView videoView;
    protected override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);
        SetContentView(Resource.Layout.VideoLayout);
        videoView = FindViewById<VideoView>(Resource.Id.SampleVideoView);

        play();
    }
    MediaPlayer player = new MediaPlayer();
    void play()
    {
        ISurfaceHolder holder = videoView.Holder;
        holder.SetType(SurfaceType.PushBuffers);
        holder.AddCallback(this);

        Android.Content.Res.AssetFileDescriptor afd = Resources.Assets.OpenFd("Splash.mp4");
        if (afd != null)
        {
            player.SetDataSource(afd.FileDescriptor, afd.StartOffset, afd.Length);
            player.Prepare();
            player.Start();
        }
    }

    public void SurfaceCreated(ISurfaceHolder holder)
    {
        Console.WriteLine("SurfaceCreated");
        player.SetDisplay(holder);
    }

    public void SurfaceDestroyed(ISurfaceHolder holder)
    {
        Console.WriteLine("SurfaceDestroyed");
        player.SetDisplay(null);
    }

    public void SurfaceChanged(ISurfaceHolder holder, Android.Graphics.Format format, int w, int h)
    {
        Console.WriteLine("SurfaceChanged");
    }

    public void OnPrepared(MediaPlayer mp)
    {
        throw new NotImplementedException();
    }
}

視頻必須位於資源文件夾中，不能繪制
