Documentation clearly says that mm and in are screen size dependent.
mm
Millimeters - Based on the physical size of the screen.in
Inches - Based on the physical size of the screen.
But when I use them, Lint says:
Avoid using "mm" as units (it does not work accurately on all devices); use "dp" instead
Is documentation wrong? And why Lint doesn't warn when using pt?
pt
Points - 1/72 of an inch based on the physical size of the screen.
