title: Dynamically generated line with glow effective
body: <p>I want to draw line with glow effect like this <br>
  <img src="https://i.stack.imgur.com/U82aJ.jpg" alt="glow line">
  <br>
  The problem - i must generate this line in program in dependence on  user's interaction ( the form of line will be generated in <code>onTouchEvent</code> - <code>ACTION_MOVE</code> ).</p>
  
  <p>Can i generate this effect without xml files or drawing premaid bitmap ?</p>
