Raw resource file type

Issue

How do you detect what kind of file the resource is? In my case there could be videos and images.

So in case it's a video, I use a VideoView; and in the case of an image, I use an ImageView?

I'm getting the resource id like this:

AssetFileDescriptor afd = context.getResources().openRawResourceFd(resourceID);

Solution

I think it's impossible without reading/ analyzing the binary data of files (like TrID). The easiest way is to prefix file names with predefined strings. For example:

• video_file_00, video_file_01…
• image_file_00, image_file_01…

Then you can use getResourceName(int) to parse the file names.
