Android Question Scale & Layout

[imgsimonebiliato]

Hello,
using GetDeviceLayout, the result for my phone is: 720x1280 = 2.0(320dip).
I read all posts of layout but I didn't understand all.
So please, what are the correct dimension to use (for button, label, image...) both for 4'' and 7'' and 10'' devices?

I can not.. I do not understand.. Please, can someone give me an example of a designer script clean and ready?
