title: Android: what is the difference between resolution and density?
body: <p>According to Android definitions, I've found that:</p>
  <ul>
  <li><p>Resolution: The total number of physical pixels on a screen</p>
  </li>
  <li><p>Density: Based on the screen resolution, the spread of pixels across the physical width and height of the screen.</p>
  </li>
  </ul>
  <p>How can I understand better the differences between the two definitions?</p>
