I'm developing an app for android devices, but i have some problems with the variety of screen sizes and different densities. So I see that before android 3.2 the solution was to create 4 folders: Small, Medium, Large and xlarge, now this method is deprecated. The problem is though running the application in similar devices the layout looks different. Which and how much folders should i do?
This is what I did for supporting all screen sizes, it can be a lot of work:
Directories:
layout-sw320dp
layout-sw320dp-land (smallest phones, 3.7" and smaller)
layout-sw360dp
layout-sw360dp-land (approximately 4-4.7")
layout-sw400dp
layout-sw400dp-land (most phones right now, 5-6")
layout-sw600dp
layout-sw600dp-land (7-8" tablets)
layout-sw720dp
layout-sw720dp-land (9" tablets)
layout-sw800dp
layout-sw800dp-land (10" tablets)
The same applies to directory names for drawables:
drawable-sw320dp
drawable-sw320dp-land
etc etc .. that's the general idea
Google's docs mentions sw720dp for 10" tablets but if you want separate layouts for 9" and 10" I discovered sw720dp is 9" and sw800dp is 10"
