Android：从内部存储播放视频时出现问题
我正在尝试使用以下代码播放视频文件：
MediaController mc = new MediaController(this);
mc.setAnchorView(videoView);
mc.setMediaPlayer(videoView);
Uri video = Uri.parse(path);
videoView.setMediaController(mc);
videoView.setVideoURI(video);
videoView.start();
对于位于 SD 卡上的视频，效果很好，但是当我尝试从内部存储播放视频时，它说无法播放视频。
现在，我认为（但不确定）这与内部存储中的视频可能没有必要的权限有关。
你怎么认为？
I'm trying to play a video file with this code:
MediaController mc = new MediaController(this);
mc.setAnchorView(videoView);
mc.setMediaPlayer(videoView);
Uri video = Uri.parse(path);
videoView.setMediaController(mc);
videoView.setVideoURI(video);
videoView.start();
With videos located on the SD card it works great, but when I try to play a video from the internal storage it says it's unable to play the video.
Now, I think (but not sure) it has something to do with the fact that maybe the videos in the internal storage don't have the necessary permissions.
What do you think?

Context.MODE_WORLD_WRITEABLE 并不意味着 Context.MODE_WORLD_READABLE。
也许您只想可读，但如果您确实想要两者，则可以将常量“或”在一起。
Context.MODE_WORLD_WRITEABLE does not imply Context.MODE_WORLD_READABLE.
Probably you only want only readable, but you can "or" the constants together if you do want both.
