The videoView.setVideoURI(vidFile);method needs to be replaced by the videoView.setVideoPath(path);method.
Here path specifies the path of the video file on the SDCARD.
该videoView.setVideoURI(vidFile);方法需要由被替换videoView.setVideoPath(path);方法。这里 path 指定了视频文件在SDCARD.
This path can be easily retrieved using the MediaStore.Video.Media.DATAproperty of that video file or by just entering the songpath statically as /sdcard/songname.
可以使用该MediaStore.Video.Media.DATA视频文件的属性轻松检索此路径，或者只需将歌曲路径静态输入为/sdcard/songname.

I also tried your code and got same error message but when I tried with video path with no blank space in path or name, it worked well. Just give it a try. e.g, file path "/mnt/sdcard/Movies/Long Drive Song - Khiladi 786 ft. Akshay Kumar_Asin-YouTube.mp4" gave the error but file path "/mnt/sdcard/Movies/Khiladi.mp4" worked well.
我也尝试了您的代码并收到了相同的错误消息，但是当我尝试使用路径或名称中没有空格的视频路径时，它运行良好。试试吧。例如，文件路径“/mnt/sdcard/Movies/Long Drive Song - Khiladi 786 ft. Akshay Kumar_Asin-YouTube.mp4”给出了错误，但文件路径“/mnt/sdcard/Movies/Khiladi.mp4”运行良好。
