Which screen size qualifiers should I choose?

Question

I'm currently developing an application that should support different screen size (phones and tablets) as well as different screen orientations. Should I use smallest width (layout-sw320dp for phones and so on) and port/land (layout-sw320dp-land ...) qualifiers to determine how many views I can fit on the screen or is there any better way to go about it?

I could also use small, normal, large, xlarge qualifiers but I read
(here http://developer.android.com/guide/practices/screens_support.html)
that those were deprecated with API level 13, which brings me to my next question.

Does API level 8, which is my minimum API level, support smallest width qualifiers?

Answer 1

No, it won't support smallest width qualifiers. (Supported only in Android 3.2+) You'll have to use the "old school" way of supporting multiple devices.
