title: How mdpi, hdpi, xhdpi folder works?
body: <p>Extract from Android Developer Guide link above:</p>
  
  <blockquote>
    <p>320dp: a typical phone screen (240x320 ldpi, 320x480 mdpi, 480x800 hdpi, etc).<br>
    480dp: a tweener tablet like the Streak (480x800 mdpi).<br>
    600dp: a 7” tablet (600x1024 mdpi).<br>
    720dp: a 10” tablet (720x1280 mdpi, 800x1280 mdpi, etc)</p>
