I'm using the Media Response to play audio in my Actions SDK (Action SDK is being used as the Fulfillment tool in my Actions Console) driven Action. At the end of each audio clip, I'm using the MEDIA_STATUS callback to advance to another mp3 file in a predefined playlist. As a result, users should be able to navigate forwards / backwards.
When testing on my Google Home mini, Google Assistant on Android and Smart Display, I can intercept "next" and advance to the next audio clip (it sends a request with intent of type MEDIA_STATUS). However, I can't properly intercept "previous" Whenever I try, the audio will restart. Real devices seems to be handling this intent on it's own and does not throw any console output (as my webhook is not accessed at all).
Dialog Flow seem to handle "next" and "previous" as follow up intents, but I need to do the same without using Dialog Flow as the Fulfillment tool.
Can anyone please help with this particular problem?
Currently only a FINISHED event is supported for the Media Response. So, you would not be able to handle distinguish between next and previous.
