android - Using different screen layouts -


i have app different versions screens (small, normal, largue, , extralargue xml files) each xml designed each type, found huawei phone screen 3.5" hvga 320x480.

my question is, should not ui of android use small configuration screen? app when running on phone uses normal configuration if nexus4 4.7" 768x1280 change that?

i tried create various types of screen (create other) multiple configurations without optimal result.

assuming 3.5" measurement on diagonal, works out 165 dpi falls mdpi (or normal screen size) bucket according android's supporting multiple screens guide.

dpi = sqrt(w^2 + h^2) / d    w width of display in pixels h height of display in pixels d physical diagonal measurement of display in inches
