title: How to get current free RAM available in android device
body: <p>In a device when we go in <code>Manage apps</code>-><code>running tab</code> then at bottom we see the used memory &amp; free memory live changing their value.</p>
  
  <p>How can we code it to my app to display just the same statistics ?</p>
  
  <p>Thanks</p>
