Answer 1

If you are doing anything in Android you should use dip or dp. dip is for pixel density. px is for pixels.

Since the number of pixels is different on every device, you should go ahead with dip.

Answer 2

px
Pixels - corresponds to actual pixels on the screen.

dp or dip
Density-independent Pixels - an abstract unit that is based on the physical density of the screen. These units are relative to a 160 dpi screen, so one dp is one pixel on a 160 dpi screen. The ratio of dp-to-pixel will change with the screen density, but not necessarily in direct proportion. Note: The compiler accepts both "dip" and "dp", though "dp" is more consistent with "sp".

sp
Scale-independent Pixels - this is like the dp unit, but it is also scaled by the user's font size preference. It is recommend you use this unit when specifying font sizes, so they will be adjusted for both the screen density and user's preference.
