Analysis of video files in Android assets files _android

This article illustrates the problem of video files in Android playback assets files. Share to everyone for your reference, specific as follows:

Today did a function, is to play the project inside the video file, not playing SD card video files.

I started trying to put the video files in the assets file directory.

This is because it was written before WebView loaded the assets folder:

WebView = new WebView (this);
Webview.loadurl (file:///android_asset/sample3_8.html);

And so on, I try to put the video video.3gp in the assets directory and write the following code:

Intent it = new Intent (intent.action_view);
Uri uri = uri.parse (name);
It.setdataandtype (URI, "video/3gp");
StartActivity (IT);

Launched the Android player, prompting for some information (not logged), presumably means that the file cannot be played on the path below/Unable to find the path file.

Google a bit, the Chinese web page there is little solution to the explanation, according to the Convention, to http://stackoverflow.com search answers, found this post:

I want to play a video from my assets or raw folder into my app Inandroid

The final solution to the video files in the Android Project project is:

1. Put the video file under the Res/raw file of Project engineering.

2. The video file must be an Android support video format (3GP,WMV,MP4), and the name must be lowercase, data, underscores, for example: My_video_file.mp4

3. When you refer to this resource file in your code, you must use the Rstatics class and remove the suffix of the file: R.raw.my_video_file

4. This activity class should have a helper method Getpackagename () that makes it easier for you to construct the correct URI in your code.

Videoview vv = (videoview) This.findviewbyid (R.id.videoview);
String uri = "android.resource://" + getpackagename () + "/" + R.raw.my_video_file;
Vv.setvideouri (Uri.parse (Uri));
Vv.start ();
