To declare different layouts and bitmaps you'd like to use for the different screens, you must place these alternative resources in separate directories/folders.

MyProject/ res/ drawable-xhdpi/ awesomeimage.png drawable-hdpi/ awesomeimage.png drawable-mdpi/ awesomeimage.png drawable-ldpi/ awesomeimage.png
Any time you reference
@drawable/awesomeimage, the system selects the appropriate bitmap based on the screen's density.
