My goal is to create 6 images of different densities that are the same size across the 6 generalized Android screen densities.
From reading Android's documentation on supporting multiple screen sizes I understand the dpi unit (dots per inch) really represents physical pixels per inch.
In my understanding, this means an image that is 160 pixels by 320 pixels on a 160 dpi screen will show up the same as an image that is 640 pixels by 1280 pixels on a 640 dpi screen. And both images will appear to be about 1 inch by 2 inches on their respective screen configurations. Is my understanding correct here?
