How to play videos from SD Card

问题

I was creating a simple app which stream videos from net and I made it but now I want to change the code so that I can play video files from my SDCard

original code:

Uri vidFile = Uri.parse("MY SITE HERE");
VideoView videoView = (VideoView) findViewById(R.id.VideoView);
videoView.setVideoURI(vidFile);
videoView.setMediaController(new MediaController(this));
videoView.start();

So please help me with changing the code so that it can play videos from my mobile memory card.

回答1:

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.

This path can be easily retrieved using the MediaStore.Video.Media.DATA property of that video file or by just entering the songpath statically as /sdcard/songname.

回答2:

Uri vidFile = Uri.parse(
   Environment.getExternalStorageDirectory().getAbsolutePath()+"filename");
... 

the rest of the code will be same.

回答3:

In place of

videoView.setVideoUri(vidFile)

use

videoView.setVideoPath("/sdcard/SONG.").

Let me know.

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.
