title: Push Notifications in Android Platform
body: <p>I am looking to write an app that receives pushed alerts from a server. I found a couple of methods to do this.  </p>
  
  <ol>
  <li>SMS - Intercept the incoming SMS and initiate a pull from the server</li>
  <li>Poll the server periodically</li>
  </ol>
  
  <p>Each has its own limitations. SMS- no guarantee on arrival time. Poll may drain the battery.</p>
  
  <p>Do you have a better suggestion please? Thanks very much.</p>
