Developing for multiple devices

onemorechance

I am interested to know of techniques that people use to accommodate the various types of Android devices, mostly with regard to screen size and pixel density.

I am going down the line of using one drawables folder with (xml) shapes. Size values are taken from multiple values folders.

Also multiple layout folders.

When creating the multiple layout and values folders, I go for:

orientation_screensize_pixeldensity.

Do ye think that screen size and pixel density is enough?

Or should one accomodate significant differences in say a large screen size which in theory can be 4 - 7 inches, and have any pixel density?

I would be most interested in solutions which don't use fragments in Android 3.0 (API level 11).
