title: How to create ImageView pulse effect using nine old androids animation
body: <p>I wonder how I should create a pulse effect using nine olad androids framework animation.</p>
  
  <p>To understand better lets say you have an ImageView and want to have a "pulse" effect like
  make the image little smaller and then back to original size, scaling will be centered.</p>
  
  <p>I use nine olad androids for backward compatibility.</p>
  
  <p>Any other option is welcome.</p>
  
  <p>Thank you.</p>
