I think you need NotificationCompat
from the Support library, you can use this code to generate a notification, adapt it as you need
NotificationManager notificationManager = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(icon)
.setContentTitle(context.getString(R.string.app_name))
.setContentText(message)
.setDeleteIntent(PendingIntent);
mBuilder.setWhen(when);
Intent notificationIntent = new Intent(context, YOURCLASS.class);
notificationIntent.putExtra("url", url);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent intent = PendingIntent.getActivity(context, random, notificationIntent, PendingIntent.FLAG_ONE_SHOT);
mBuilder.setContentIntent(intent);
Notification notification = mBuilder.build();
notification.flags |= Notification.FLAG_AUTO_CANCEL;
// Play default notification sound
notification.defaults |= Notification.DEFAULT_SOUND;
// Vibrate if vibrate is enabled
notification.defaults |= Notification.DEFAULT_VIBRATE;
notificationManager.notify(random, notification);
