Re: [android-developers] drawable-xhdpi-v9 ?

There isn't really anything special about xhdpi -- aapt just converts that to the appropriate density value (320 for xhdpi), and the platform since API 4 knows how to pick the best density given any numbers for screen density and resource density.

Do you just mean the density configuration in general?  Surely Donut did not specifically know about xhdpi (which was only introduced in Gingerbread)?

There is no need to here, previous versions of the platform (down to API 4) know about the density configuration and will pick the correct density for you.

My apologies. I misread your question. I thought you were saying that
your minSdkVersion *was* 9, not was *less than* 9. With a
minSdkVersion of less than 9, using -v9 for resources you only want
used on 9 and higher is perfectly reasonable.

Correct.
