android - Why do we have to provide images for all device screen sizes (mobile development)? -

why have provide images screen sizes when developing mobile applications? wouldn't more efficient have 1 big image each unique image , scale image downwards whenever app beingness run on smaller device? create game's file size much smaller.

in lots of cases, wouldn't good.

if find set of designed icons, you'll see they've been independently designed each resolution: smaller ones deliberately have less detail in, because downscaling doesn't produce results.

here 2 gnome icons, same thing, 1 @ 256x256 , 1 @ 48x48. can see 48x48 1 has less detail in writing on letter, writing designed rather differently: on 256x256 1 looks middle page of document, , on 48x48 1 looks opening of letter, address @ top.
