问题 Does Firebase not work behind proxies? I am making an Android app for the students of my institute. The app does not receive the notification when it is connected to the internet through the proxy servers. But as soon as I turn on the mobile data, notifications are received.

See here; https://github.com/firebase/firebase-tools/issues/36 and here; https://groups.google.com

问题 I have successfully implemented push notifications in my two related apps via FCM and while trying to implement some logic to increment badge number on receiving the notification.

问题 I have been tryong to add FCM to my android application for almost 48 hours now. I am keep on failing with these two errors on Android Studio. I have tried all the solutions in this post.

问题 According to Firebase cloud messaging documentation, for subscribing a user to a topic I need to call FirebaseMessaging.getInstance().subscribeToTopic("news"); In my application, I need all users to be subscribed to my cloud messaging topic. Since return value is void , the question is how can I understand that subscription was successful? Is it a bad practice to call subscribeToTopic each time my application starts? 回答1: 1. How can I understand that subscription was successful? Edit: You

问题 I use Firebase as a backend. I also use FCM as one of the provided features from Firebase. FCM worked well in iOS 10, but after switching to iOS 11, push notifications stopped coming to user devices, and I myself did not receive any push notifications sent from the cloud functions or the Notification section in the Firebase Console. How to fix this problem? Update: I sent several push notifications from Firebase Notifcations, but they do not come. // MARK: - Push notification extension

问题 I'm new using the Firebase Cloud Message. I built an IOS app to receive push notifications. The app works fine. I send messages from the Firebase console and they're displayed correctly.

问题 I am using Firebase for our messaging service in our Android app. I have researched Firebase quite a bit and I understand that whether the app if running in the foreground or now will change the type of data received in the onMessageReceived method. What I am trying to accomplish is to parse the incoming data from the Remotemessage and do something different with it depending on custom tag. IE, if the Data Map contains a field called, "My_Custom_Tag", I want to completely override the
