Audio playback from custom position

Question

Hello, 
 Can an audio content provider app send the native audio player a position in the audio file to start from? I am trying to keep track of where I started and stopped an audio file, but I do not see where I can get/set that parameter? 
 If it cannot be done in an audio content provider, and it be done in a normal app? 
 
 Thank you, 
 Ryan

I don't develop audio apps, but looking at the docs it seems like if you return an ActiveContent (inherits from Content) from your ContentIterator , then you can set the playback start position. 
 developer.garmin.com/.../ActiveContent.html 
 initialize(contentRef, metadata, playbackStartPos)

Constructor

Parameters: 
 
 contentRef &mdash; ( Toybox.Media.ContentRef ) &mdash;
 
 A reference to media content

metadata &mdash; ( Toybox.Media.ContentMetadata ) &mdash;
 
 The metadata associated with referenced media content

playbackStartPos &mdash; ( Toybox.Lang.Number ) &mdash;
 
 Playback start position for the media content in seconds

To get the current position, I think you would implement ContentDelegate::onSong() to handle song notifications? 
 (Looks like playBackPosition is relative to the configured start position, and not the absolute start of the song.) 
 https://developer.garmin.com/connect-iq/api-docs/Toybox/Media/ContentDelegate.html 
 onSong(contentRefId, songEvent, playbackPosition)

Handle a notification from a system that a song has been played.

Parameters: 
 
 contentRefId &mdash; ( Toybox.Lang.Object ) &mdash;
 
 The ID referencing a ContentRef object

songEvent &mdash; ( Toybox.Lang.Number ) &mdash;
 
 A SONG_EVENT_* value indicating the triggered event

playbackPosition &mdash; ( Toybox.Lang.Number ) &mdash;
 
 The time the song has been playing in seconds, or a PLAYBACK_POSITION_* value
