I created a trivial working app project from this Gist at https://github.com/gregko/PlayerServiceSample. In the LogCat output one can see a message when a media button is pressed on a headset, when running on Android 5.x through 7.x. However it fails completely on Android 8 "Oreo", which final build Google just released. Would appreciate any hints on how to make this work under "Oreo", thanks!
