This name could conflict with other code in media. If this is really for
Android, maybe we should rename it CreateAndroidCdm. Otherwise, should we be
using the factory function for desktop too?

This is a static function that is invoked to create a platform specific CDM so
CreateAndroidCdm is not suitable (the same static function will be used to
create a Chromecast CDM).

If it's only used for platform-based (browser process) CDMs, maybe this should
be CreateBrowserCdm() or something.

This file could already be part of media/base/ (at the same level as MediaKeys).
Nothing is android specific here.

Good point. Done.
