Assuming you meant the device's screen sizes (you wrote "of a device", not
the screen size) then the sizes are correct for most of the time.
When the app is running on a device that has no physical buttons or running
on an ICS+ device while being targeted lower (thus causing the menu bar to
show) the screen size is reported sans that bar.
As an example, a galaxy nexus while being 720x1280 (4.65 inches diagonal)
is reported as 720x1184 (4.36 inches diagonal).
