Playing preloaded media

Hello Everyone,

I am new to the API, and I'm wondering if there is a way to lookup media already on a wearable and play that media.  For example, I have several mp3s loaded to my device, and I'd like to list and play them.  I know that the native controls already do this, but I'm looking to extend some functionality.

For audiobooks, I'd like my watch and phone to sync so that the position in the audiobook is never lost between the two devices.  I have the mp3 on both wearable and phone, and I'd like the phone and watch to sync periodically to let each know the current position in the mp3.

I cannot find anything in the API about loading media (or even storing audio resources in an app)

Thank you,

Ryan
