There's no documentation just yet, but it is coming.
Fortunately, there's nothing special that you need to do for the Android application. As long as your intent-filter will support android.intent.action.SEND and support the right mimeType for your data, it will show up in the share menu.
Hope this helps

If you've registered an intent-filter with android.intent.action.SEND, you should be able to see it with bb.action.SHARE, from a native application.
I believe there's a minor bug open for custom mime-types though.
