I want to publish two .apks of my application on the android market so I can support a smaller apk for older devices. I understood that I have to use different filters in my AndroidManifest file. I have two versions of my program, one for screens 480 x 320 and smaller (320 x 240), and one for any other screen bigger than 480 x 320. But I'm a little confused, what's the best filter to use: screen density or screen size. And what is the size of 480 x 320? Maybe android:normalScreens, but I'm not quite sure. Thanks in advance!

If you have resources for all the screen densities in their respective folders, you don't need to set the density filter, size filter will do.

Yes.
