nativescript-local-notifications: Everything is fine... But Notification doesn't show up.

I installed the plugin for Nativescript 2.4 (Android). So far I used the demo code and everything seemed fine.

I also got the console.log, that the Notification is scheduled. But there is no Notification showing up… And I don’t get any errors…

Someone experiencing the same problem? Is there a solution?

  LocalNotifications.schedule([{
    id: 1,
    title: 'The title',
    body: 'Recurs every minute until cancelled',
  }]).then(
      function() {
        console.log("Notification scheduled");
      },
      function(error) {
        console.log("scheduling error: " + error);
      }
  )
