id say ideal would be to use the highest screen density so the app will scale it down for lower screen resolutions that way you wont loose quality on bigger screens, heres the chart i got off of here

xlarge screens are at least 960dp x 720dp
large screens are at least 640dp x 480dp
normal screens are at least 470dp x 320dp
small screens are at least 426dp x 320dp
Generalised Dpi values for screens:

ldpi Resources for low-density (ldpi) screens (~120dpi)
mdpi Resources for medium-density (mdpi) screens (~160dpi). (This is the baseline     density.)
hdpi Resources for high-density (hdpi) screens (~240dpi).
xhdpi Resources for extra high-density (xhdpi) screens (~320dpi).
Therefore generalised size of your resources (assuming they are full screen):

ldpi
Vertical = 426 * 120 / 160 = 319.5px
Horizontal = 320 * 120 / 160 = 240px
mdpi
Vertical = 470 * 160 / 160 = 470px
Horizontal = 320 * 160 / 160 = 320px
hdpi
Vertical = 640 * 240 / 160 = 960px
Horizontal = 480 * 240 / 160 = 720px
xhdpi
Vertical = 960 * 320 / 160 = 1920px
Horizontal = 720 * 320 / 160 = 1440px

px = dp*dpi/160
