title: eliminate duplicates in Android drawable folders
body: <p>I want to have two different layouts (in layout and layout-land), one that is landscape and one that is portrait.  Both these layouts will use some of the same images, eg,. drawable-hdpi and drawable-land-hdpi currently have copies of the same image 'horn.png' and same is for drawable-xhdpi and drawable-land-xhdpi, etc... Is there a way to not duplicate the images everywhere?</p>
