Not at this time. We're being very limiting in what APIs we expose to applications that want to go into the store initially until we can make sure that:

• it'll meet the usecases you want
• we can promise forwards-compatibility (good quality API, and being careful with the implementation to avoid exposing internal implementation details etc)
• it's well documented as to how to use it, and how to use it well

I kicked off some discussion earlier today about how we prioritize exposing new API. I imagine we'll want to offer up some kind of voting mechanism to store developers, but there's nothing clearly decided there yet.

I'm not at all knowledgable on the Android front of things, so I can't answer you directly. I'll try remember to ask around and get back to this.
