Initialize FirebaseApp for FCM after Permissions granted

[AlleSchonWeg]

Hi,
i read the docs and added RegisterFirebaseServices

		private static MauiAppBuilder RegisterFirebaseServices(this MauiAppBuilder builder) {

			builder.ConfigureLifecycleEvents(events => {
#if ANDROID
				events.AddAndroid(android => android.OnCreate((activity, _) =>
					CrossFirebase.Initialize(activity, () => Platform.CurrentActivity)));
#elif IOS
				events.AddiOS(iOS => iOS.FinishedLaunching((_, __) => {
					CrossFirebase.Initialize();
					FirebaseCloudMessagingImplementation.Initialize();
					return false;
				}));
#endif
			});

			builder.Services.AddSingleton(_ => CrossFirebaseCloudMessaging.Current);
			return builder;
		}

to the app lifecycle.
I assume CrossFirebase.Initialize register the app at Firebase by calling FirebaseApp.InitializeApp(...). If this is correct then the app registers at Firebase before the user has granted the permissions.
In my case i display a rationale page to inform the user why the permissions are needed. After the user read the informations i call Permissions.RequestAsync<Permissions.PostNotifications>() to display the android dialog and i want only register at Firebase
when the user granted the permission. Is that possible?
Thank you.

If your concern is that a permissions dialog will display 'too soon', then I don't think you need to change anything. Simply initializing Firebase at startup doesn't do that.

If you have some other reason to not want FCM to automatically initialize, then you can follow the documentation at https://firebase.google.com/docs/cloud-messaging/android/get-started#prevent-auto-initialization

Hi,
requesting a fcm token without user approval is not GDPR-compliant. That's the reason. This is a European Data Protection Regulation.
FCM tokens (device identifiers) are considered personal data under GDPR.
An app which is available in EU countries should/must receive user approval before request the token.
