Integration with Android media importer?

[nickc]

Hi, The description in the Play Store refers to support for usb otg, eg nexus media importer, usb host controller etc. I have installed both the latter, but I can't see how to get bsplayer to work with either of them, or them to work with bs player. Using an unrooted nexus 10. I'm wanting to be able to play mp3 files directly from a usb stick connected to the tablet via an otg cable and using the player of my choice. I'd imagined it would be a breeze and can't understand why it's so difficult. I love my new nexus but this issue is really taking the shine off. I can browse and play the files in media importer, but can't find any option to choose or set a player. If I open bsplayer, I can't find a way to access the usb stick, even with media importer open. What am I missing?
