How many layout resource folders do i really need to cover all android devices -

-

i have found many questions , answers on topic , have read through developer guidelines many different device sizes out , no doubt more new sizes in future, best practice cover of these? have seen people mention using layout-small layout-normal layout-large layout-xlarge, enough cover majority of devices out! have seen others not use them deprecated , instead should use layouts smallest width i.e layout-sw380dp layout-sw480dp , forth. in mind find self mixing layouts , honest gets confusing! take @ picture example i have many layouts, need of these? experienced android developers ask, how many , layout resource folders use target huge range of devices out there? usually keep auto-generated directories because "default" structure can create application many devices. if want create app uses more graphical details, should use created directory in screenshot edit: default structure = auto-generated directories new project android studio :)
