When I have used Local Notifications on Android in my Unity3D projects, I was able to turn on flags to enable the default vibration and light blinks in java plugin doing something like this:
Notification note = new Notification();
…
note.defaults |= Notification.DEFAULT_VIBRATE;
note.defaults |= Notification.DEFAULT_LIGHTS;
note.flags |= Notification.FLAG_SHOW_LIGHTS;
When testing Local Notifications with Corona, I only see an option for sound, but no vibrate or lights. Anything I I am missing?
