Again, depending what these images are used for, you may want to use 9-patch png files. Also have a look at Supporting Multiple Screens topic at Android DevGuide

For best quality, use different size images for all devices.

Another way is to scale down images to whatever the size the device is using. If you are doing this on the device, it might take a lot of time, or there may be scaling artifacts.

Yet another way is to not use bitmap images, rather one kind or another of vector based graphics.
