Notification message not shown when app is in the background

Hi, I have a problem using this plugin, could use some help here…

I’m using curl to post a notification message to Firebase, like so:

Headers:

Content-Type:application/json
Authorization:key=[MY_AUTH_KEY]

JSON:

{
    "to" : "[MY_FIREBASE_KEY]",
    "content_available": true,
    "notification" : {
        "body" : "great match!",
        "title" : "Portugal vs. Denmark",
        "click_action": "helloworld",
        "icon": "notification_default",
        "sound" : "default",
	"priority": "high",
	"badge": 1
    }
}

Using the app sample code downloaded from Firebase, this works… So I know that my Firebase key and my authorization key are correct (and also my Apple certificate). When the app is in the background, I receive a sound and a notification in the notification centre on iOS.

Now I’m trying to use my own sample code, with the following result: When the app is in the foreground, an event is triggered and I receive the data, so that works perfectly! Now when the app is in the background, I would expect that (as in the sample above), iOS will play a sound, show a badge and display a notification in the notification centre…but it does not! Nothing happens…

Is something wrong with the plugin? Can anybody point me in the right direction?

Source code (main.ts) below:

// this import should be first in order to load some required settings (like globals and reflect-metadata)
import { platformNativeScriptDynamic } from "nativescript-angular/platform";

import { AppModule } from "./app.module";

import firebase = require("nativescript-plugin-firebase");

firebase.init({
  // Optionally pass in properties for database, authentication and cloud messaging,
  // see their respective docs and 'iOSEmulatorFlush' to flush token before init.
  iOSEmulatorFlush: true,
  onPushTokenReceivedCallback: function(token) {
      console.log("Firebase push token: " + token);
  },
  onMessageReceivedCallback: function(message) {
      console.dump(message);
      console.log("Title: " + message.title);
      console.log("Body: " + message.body);
      // if your server passed a custom property called 'foo', then do this:
//      console.log("Value of 'foo': " + message.foo);
    }
}).then(
  (instance) => {
    console.log("firebase.init done");
  },
  (error) => {
    console.log("firebase.init error: " + error);
  }
);

platformNativeScriptDynamic().bootstrapModule(AppModule);

@sudhanshu-15 I’m looking at this later today with the demo app.

@simonettoa You’re doing everything right, except you need to remove <key>FirebaseAppDelegateProxyEnabled</key><false/> from app/app_resources/ios/xx.plist
