Are Earplay and Bose AR available on Android?
Not right now, unfortunately.
Although we released Codename Cygnus on Android, we next shifted our focus to Google Assistant. Earplay now works with Google Assistant and on Android devices you can invoke the assistant and use the Action title (like "Google, play Earplay") to get a story.
