how to determine file extension from mime type?

I am trying to figure out the best way to determine a file extension given a mime type in android.

This is typically coming in the form of a content uri so I get the mime type as follows:

ContentResolver contentResolver = context.getContentResolver();
String mimeType = contentResolver.getType(uri);

From there I have been using MimeTypeMap:

MimeTypeMap mimeTypeMap = MimeTypeMap.getSingleton();
String extension = mimeTypeMap.getExtensionFromMimeType(mimeType);

This works great in most cases however there are a few glaring holes, one of them being that there is no entry for "audio/mp4".

Is there a more complete mapping I can use that is built into Android? Or any other ideas?

No, sorry.

Or any other ideas?

Bake a MIME type map of your own into your app. See:

...and so on.
