Notification shown each time I open the app

Hi everyone, I’m using code presented by Jen looper to recieve FCM messaging. in android each time I open the app, an empty dialog.alert jumps even though there is not FCM message sent by Firebase, any idea please ?

here is a snapshut of the code, thanks in advanced:

setTimeout(function () {
  let firebase = require("nativescript-plugin-firebase");
  firebase.init({
    onPushTokenReceivedCallback: function (token) {
      console.log("Firebase push token: " + token);
    },
    onMessageReceivedCallback: function (message) {
      dialogs.alert({
        title: "Push message: " + (message.title !== undefined ? message.title : ""),
        message: JSON.stringify(message),
        okButtonText: "W00t!"
      });
    },
    //persist should be set to false as otherwise numbers aren't returned during livesync
    persist: false,
    //storageBucket: 'gs://yowwlr.appspot.com',
    onAuthStateChanged: (data: any) => {
      console.log(JSON.stringify(data));
      if (data.loggedIn) {
        BackendService.token = data.user.uid;
      }
      else {
        BackendService.token = "";
      }
    }
  }).then(
      function (instance) {
        console.log("firebase.init done");
      },
      function (error) {
        console.log("firebase.init error: " + error);
      }
  );
}, 3000);

Hi @rkhayyat , I’ve noticed in our app that the event ‘onMessageReceivedCallback’ is called each time app returns from background, so in your code should show alert each time. Simple workaround for us in the meantime was to look and the message data structure which is different than an actual push notification in our system, so if not in correct structure ignoring.

Hope this helps, Thanks
