Android Retina Display

I was wondering how I am suppose to scale my images for android phones. For example, let’s say I have an image with the dimensions 30 X 15. What do I multiply the image resolution by to use the @1_5x suffix? Also, should I use the @1_5x suffix for android phones and then use the @2x for the tablets?
-Thanks!!

I use only double pixel sized images @2x and re-size them

so no 1.5x image, just the normal and the 2x

I trigger the retina devices from the 1.5 ratio for android devices
I do that using -webkit-min-device-pixel-ratio: 1.5
and then I always resize the background-size to the original dimensions (which means yes all my images are background, sure)

hope it helps
