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.

How to handle this? I am sure its a common scenario and there will be a solution.

I checked many posts in stack overflow but most of them are for iOS. I want for Android

AirshipConfigOptions options = AirshipConfigOptions.loadDefaultOptions(this);

  UAirship.takeOff(this, options);
Logger.logLevel = Log.VERBOSE;


PushManager.shared().setIntentReceiver(IntentReceiver.class);
PushManager.enablePush();
