title: How to communicate between two different android apps
body: <p>I have a Notification started in the system bar by one application(Notification Manager), how can i remove/stop it from another application ? Can i use a broadcast receiver ? Will that work ?</p>
  
  <p><strong>Description:</strong>
  Application A and B is installed. Application B is installed without the launcher option, so it is visible only in settings/apps (so the app is not started). Now App A has to start a service in App B.. Is this possible?</p>
