File resolution without extension

Issue details

When I generate cached MP3 files from other game resource files, I don’t want the extension on purpose, but I need extension when I play it

Reproduction steps/code

package com.badlogic.gdx.files;

public class FileHandle{

...

    protected String extension;

    /**
     * Add an attribute and a method to find a suitable parser for the no extension file.
     * Call the last line of all constructor methods  ex: setExtension(null);
     * @param extension suffix
     */
    public void setExtension(String extension) {
        if (extension == null) {
            String name = this.file.getName();
            int dotIndex = name.lastIndexOf(46);
            this.extension = dotIndex == -1 ? "" : name.substring(dotIndex + 1);
        } else {
            this.extension = extension;
        }
    }

   ...

    /** Returns the file extension */
    public String extension () {
        return extension;
    }

}

Extension is part of the path, changing extension would mean changing the path which mean it’s not the same file handle. Faking things like this would totally change what a FileHandle is and make it inconsistent. That’s not a valid use case IMO.

I agree it would be odd to set an extension on a FileHandle, as the extension comes from the path.

Seems OP’s issue is that Audio newSound/newMusic uses the extension to decide how to parse the file. We’d need to add a new Audio method to allow choosing how the file is parsed without using the extension. A workaround may be to subclass FileHandle and return a hardcoded value for the FileHandle extension method. On the desktop with an absolute path you can just subclass FileHandle rather than a backend specific class.
