The limited documentation is at 
Glad to hear that Elanor might be working on some more documentation. This 
feature (like push notifications and mobile camera) are difficult to test since 
the emulator either doesn’t work or has extremely limited functionality.

I found this code snippet in an old project where I was taking a screenshot of 
part of the screen and trying to share to Facebook or Twitter.
