How to use android's VideoView control to play video files on the sd card do?

Recently doing android multimedia learning, adding when using VideoView to play video files online video and video works have played a success, but the video on the player sd card is experiencing a problem.
After checking out of the question because of the path of the. The Internet to find the path of several ways to write: (1) video.setVideoURI (Uri.parse (Environment.getExternalStorageDirectory () + "/ test.mp4"));
(2) video.setVideoURI (Uri.parse ("file :/ / / sdcard/video/test.mp4"));
(3) video.setVideoURI (Uri.parse ("/ sdcard/test.mp4"));
These types of writing path methods are tried, either flat or in the tests were prompted not play on the simulator, this problem has been plagued for several days, there is no master to help me ah! In the end is where the problem? First thank you ・ ・ ・ ・ ・<-! Main posts under Banner (D4) -><-! Posts under the main text (D5) ->

These days have been busy, no time perspective. Later, after research questions eventually resolved. Said the same with the third floor, and is now on the path of sdk. Different versions of the set of paths are different. I use 2.2 Both versions are correct.
video.setVideoURI (Uri.parse ("/ mnt/nand/sdcard/test.mp4"));
video.setVideoURI (Uri.parse ("file :/ / / mnt/nand/sdcard/test.mp4"));
Another very important point is that the wording used by plate test and simulator test path is different. The above is written in the test plates.
If you are using the mini's words are written.
video.setVideoURI (Uri.parse ("/ mnt/sdcard/test.mp4"));
video.setVideoURI (Uri.parse ("file :/ / / mnt/sdcard/test.mp4"));
Nand directory is to remove this layer. Specific directory in the end is what we can according to their own situation to determine if the tablet can be used with which file browser to a specific path step by step to see your sd card. If you only use the simulator, then you can expand the file directory in the File Explorer android open views to determine the specific path.
I have in mind is to these. There does not seem to textures, such as time of day and then carefully summarize, the written document issued Come on. There do not understand friends can continue to leave a message, we'll continue the exchange under.

2.1 Get me the above said path is the same as ah:
video.setVideoURI (Uri.parse ("/ sdcard/test.mp4"));
video.setVideoURI (Uri.parse ("file :/ / / sdcard/test.mp4"));
Both simulator written words are possible, as opposed to 2.2 mmt of this layer is to remove the directory on the line. No tablet on hand was not tested, and does not know what the situation is, but you should look at methods to determine the path I wrote above, in accordance with the method to determine the path that should be no problem with it!

Screen path automatically get it, get only one path to the specified file is too simple, and took them to automatically search sd card not very good? In the 4.1 version does need to add "/ mnt/sdcard/pengin.mp4 /" in order to develop play the file for playback.
