i am working on photos options in my app.

Intent for selecting wallpaper with wallpaper region highlighting

I would like to know if it's possible to create an Intent that makes the gallery cropper show wallpaper highlighting. This feature has been introduced in Honeycomb. To get an idea of what I'm looking for have a look at the tablet on the image (the three blue rectangles).
