Can't access notification data when the app is in background or killed

Hi!

First of all, great work with this library!

react-native@0.48.0
react-native-fcm@10.0.2
OS: Android - Emulator - 7.0.2

When my app is in foreground, its working perfectly, I receive the data in this function

FCM.on(FCMEvent.Notification, async (notif) => {

And I can handle everything

But when the app is in background, the notification is received, but when I tap the banner, the app goes foreground, the same function is triggered, but the notif object is different, and don’t contains my data.

When the app is killed, also the notification is received, but when I tap the banner, the app starts, the FCM.getInitialNotification() is triggered, and my notif object doen’t also contain the data, the same behaviour than in background

I am testing the format of the messages using node-gcm library, of firebase web interface, but nothing works.

This is a sample of my message:

let message = new gcm.Message({
	priority: 'high',
	content_available: true,
	timeToLive: 3,
	data: {
		key1: 'message1',
		key2: 'message2'
	},
	notification: {
		title: "Hello, World",
		icon: "ic_launcher",
		body: "This is a notification that will be displayed if your app is in the background."
	},
	custom_notification: {
		key1: 'message1',
		key2: 'message2'
	}
	
});

How should I proceed to send and receive data in those cases? Because is driving me crazy.

If you need more data, ask for it 😃

Thanks!!

EDIT:

I have two activities in my native part, as I am handling a splash screen in the native way. can this be causing this effect?

This is my manifest.xml. I don’t want to handle local notifications, only remotes

issue 2: try remove the notification part and add "content_available": true. See if the notification gets delivered. issue 3: App should wake up after reboot or system kill because of memory shortage. Swiping away in task center will prevent app waking up. System behavior.

I would not rely on notification and sync data with server on launch for both Android and iOS because user can turned off notification.
