title: How do I get my Gmail friends online status
body: <p>I am developing one web application using (PHP JavaScript). 
  I stuck to one point that I wanted to get my Gmail friend(s) online status.</p>
  
  <p>e.g. I would provide one of my Gmail friend IDs i.e. abc@gmail.com as input to the API (if such an API is exist) and ultimately I wanted to track whether he is online or offline through normal script (PHP/JavaScript/jQuery/other).</p>
  
  <p>Please folks provide me your necessary pointer(s) in this case. Does such API/library exist in PHP, Java script, jQuery or any other? How do I achieve this?</p>
