title: Push notification does not happening when app is not running - android
body: <p>I am using Urban Airship for Push notification. Its works like a charm but just found that its did not sending push notification when application is not running.</p>
  
  <p>How to handle this? I am sure its a common scenario and there will be a solution.</p>
  
  <p>I checked many posts in stack overflow but most of them are for iOS. I want for Android</p>
  
  <pre><code>AirshipConfigOptions options = AirshipConfigOptions.loadDefaultOptions(this);
  
    UAirship.takeOff(this, options);
  Logger.logLevel = Log.VERBOSE;
  
  
  PushManager.shared().setIntentReceiver(IntentReceiver.class);
  PushManager.enablePush();
  </code></pre>
  
  <p>I have below code in Manifest Fie</p>
  
  <pre><code>   &lt;!-- REQUIRED for Urban Airship GCM--&gt;
