(iSideMenu is currently available. It is similar to jfeinstein's SlidingMenu library)
B4ADrawer might be added to B4i and B4J. The challenging feature is to properly handle the gesture without consuming it too early and preventing the user from interacting with the views near the left side.
Yes, I've tried that library, and just like jfeinstein's library, it's very easy and nice to work with. But as I'm looking for "drawer over content, with dark background", it's not really an option, as far as I can tell. Just like jfeinstein it pushes the content to the side.
