  <p>I am new to Android and I was trying out <a href="http://developer.android.com/resources/tutorials/views/hello-listview.html" rel="noreferrer">this tutorial</a></p>
  
  <p>In that tutorial, they used the unit "sp" for textSize attribute and "dp" for other attributes.</p>
  
  <p>Please tell me how sp differs from dp?</p>
