If you are at all serious about developing an Android app for more than one type of device, you should have read the screens support development document at least once. You should always use dp units whenĭefining your application's UI, to ensure proper display of your UI on

The conversion of dp units to screen pixels isĮquals 1.5 physical pixels. At runtime, the system transparently handlesĪny scaling of the dp units, as necessary, based on the actual density The density-independent pixel is equivalent to one physical pixel on a 160ĭpi screen, which is the baseline density assumed by the system for a Layout dimensions or position in a density-independent way. Pixel unit that you should use when defining UI layout, to express Only with screen size and density, as specified by the generalized Not work directly with resolution applications should be concerned When adding support for multiple screens, applications do Resolution The total number of physical pixels onĪ screen. Only do different devices operate in different orientations byĭefault, but the orientation can change at runtime when the user This is either landscape or portrait, meaning that the screen'sĪspect ratio is either wide or tall, respectively. Orientation The orientation of the screen from the user's point of For simplicity,Īndroid groups all actual screen densities into six generalizedĭensities: low, medium, high, extra-high, extra-extra-high, and 'low' density screen has fewer pixels within a given physical area,Ĭompared to a 'normal' or 'high' density screen. Screen usually referred to as dpi (dots per inch). The number of pixels within a physical area of the Generalized sizes: small, normal, large, and extra-large.

Pretty much everything about this and how to achieve the best support for multiple screens of different sizes and densities is very well documented here:Īctual physical size, measured as the screen's diagonal.įor simplicity, Android groups all actual screen sizes into four Note, the Android documentation is inconsistent on what sp actually stands for, one doc says 'scale-independent pixels', the other says 'scaleable pixels'.įrom Understanding Density Independence In Android: Use this unit when specifying font sizes, so they will be adjustedįor both the screen density and the user's preference. > Scaleable Pixels OR scale-independent pixels - this is like the dp unit, but it is also scaled by the user's font size preference. Note: The compiler accepts both 'dip' and 'dp', though 'dp' is more consistent with 'sp'. The ratio of dp-to-pixel will change with the screen density, but not necessarily in direct proportion. These units are relative to a 160ĭpi screen, so one dp is one pixel on a 160 dpi screen. > Density-independent Pixels - an abstract unit that is based on the physical density of the screen. > Points - 1/72 of an inch based on the physical size of the screen. > Millimeters - based on the physical size of the screen. Inches - based on the physical size of the screen. Pixels - corresponds to actual pixels on the screen. From the Android Developer Documentation:
