android - Notification received but not showing -

i'm adding urban airship push notifications android app. custom broadcastreceiver receiving notifications when send test push. here's onreceive() method.

public class intentreceiver extends broadcastreceiver {      @override     public void onreceive(context context, intent intent) {         if(intent == null)             return;      string action = intent.getaction();      if (action.equals(pushmanager.action_push_received)) {         int id = intent.getintextra(pushmanager.extra_notification_id, 0); //breakpoint here          log.w("my app", "received push notification. alert: "                 + intent.getstringextra(pushmanager.extra_alert)                 + " [notificationid="+id+"]");          logpushextras(intent);      } else if (action.equals(pushmanager.action_notification_opened)) {         //other stuff here     } 

execution stops @ breakpoint (position shown in comment) , details logged.

no notification shown in notification area though. in other app ua push notifications, think did, doesn't seem working time.

i suspect i've done wrong in manifest file or i've forgotten implement class somewhere.

any ideas?

extra info

extended application:

public class extendedapplication extends application {      public void oncreate(){         airshipconfigoptions options = airshipconfigoptions.loaddefaultoptions(this);         uairship.takeoff(this, options);         pushmanager.enablepush();          pushpreferences prefs = pushmanager.shared().getpreferences();         log.e("my app", "my application oncreate - app apid: " + prefs.getpushid());          pushmanager.shared().setintentreceiver(intentreceiver.class);     } } 

edit

i've tried adding

pushmanager.shared().setnotificationbuilder(new basicpushnotificationbuilder()); 

to extendedapplication suggested in this post.

i sending test push blank "alert" field ua site. tried text in there , works. don't know why, don't think that's should fail silently.

moral of story: don't leave alert field blank.
