I'm not an expert in working with the emulators, but in the docs for the storage emulator here it says:

"Using the Admin SDK, only uploading files, downloading files, and modifying file metadata are supported. Other functionality provided by Google Cloud Storage client libraries is not yet available."

I haven't been able to get getFiles() working either, so in my tests I just keep track of what I'm uploading to the emulator, and then check for the existence of each item using the bucket.file(filename).exists() method. Perhaps the getFiles() method just isn't implemented yet for emulator?
