Two properties that effect the way your application looks:
Screen size: the number of horizontal and vertical pixels on a screen.
Pixel Density:the abstracted number of pixels in an inch square.
different images for different pixel densities
hdpi: high pixel density (around 240 DPI)
mdpi: medium (around 160 DPI)
ldpi: low (around 120 DPI)
Real size is the whole reason for the pixel density groupings.
