问题 This question already has an answer here : Schedule a push notification with Firebase Cloud Messaging [duplicate] (1 answer) Closed 2 years ago . I have read every piece of documentation I could find but still do not know if this is possible. Can I schedule push notifications for a specific time if I am a user?

问题 Update: Google Bug Report Description (as suggested by google dev advocate in comments on answer 1, filed a bug report; updating the content here since it more succinctly and precisely describes the problem) I do not need or want to show any notifications to my user. And many users are not willing to give notifications permission because they assume they will start seeing notifications. But I wish to push data to my web page from the server.

问题 In Test app, I have implemented FCM for sending notification messages using https://github.com/firebase/quickstart-android/tree/master/messaging For testing I sent the message( 8:42 PM ) from firebase console using the "New Message" under Notification.

问题 I want to enable Firebase Cloud Messaging for push notifications for my Android app. In the google-services.json file needed for push notifications there's a field called "api_key". Right now I have "api_key": [{ "current_key": "" }] Should I put the Web API Key I see on my Firebase Console? 回答1: The api_key value in google-services.json is not used by FCM. (it is used by other Firebase libraries) Generally speaking do not touch the google-services.json that is provided by the Firebase

问题 How can I eliminate the opportunity of an app user to call FirebaseMessaging.subscribeToTopic(String) in order to handle topic management only server side? 回答1: Firebase Cloud Messaging topics are public.

问题 As per the Firebase Notification docs: Notification messages are always collapsible. I was trying to figure out if they have some intrinsic collapse_key . And if so, does that count towards the collapse_key limit of 4 per device? 回答1: You are correct. All the notifications sent from the Web Console are collapsible. Which means they have an implicit collapse_key If a device has a pending-to-be-delivered messages from the Web Console, this implicit collapse_key counts towards the limit of 4 per

问题 We are about to switch to Firebase notifiaction API from Parse.com (that are retiring their service in jan 2017) to send push notification to our android and iOS Apps. My question now is that I can't see any statistics about counts of successful deliveries and opens in the Firebase Console for a specific message ?

问题 I've searched a lot about notifications when the app is in the background or closed. I'm using Firebase Cloud Messaging by the way. It won't work for me.
