  <pre><code>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
