问题 In my MainActivity in my log, I can see the token using FirebaseInstanceId.getInstance().getToken() and it display the generated token. But it seems like in my MyFirebaseInstanceIDService where it is extends to FirebaseInstanceIdService , the onTokenRefresh() is not called, where in this function it was said that the token is initially generated here. I needed to call sendRegistrationToServer() that\'s why I\'m trying to know why it doesn\'t go in the onTokenRefresh() . Here is my code public

问题 I\'m attempting to send out a notification to all app users (on Android), essentially duplicating what happens when a notification is sent via the Firebase admin console. Here is the CURL command I begin with: curl --insecure --header \"Authorization: key=AIzaSyBidmyauthkeyisfineL-6NcJxj-1JUvEM\" --header \"Content-Type:application/json\" -d \"{\\\"notification\\\":{\\\"title\\\":\\\"note-Title\\\",\\\"body\\\":\\\"note-Body\\\"}}\" https://fcm.googleapis.com/fcm/send Here\'s that JSON parsed

问题 I have working with FCM console to send push notification and it has an option to schedule the delivery date. But in the references, this API is not documented as an option.

问题 I want to open application automatically when notification is received, is this possible with Firebase and new FCM notifications? I know I can set click_action but that\'s only for customizing which activity will start on notification click, I need something that will start automatically when notification is received. I tried the quick start messaging firebase sample and there is a onMessageReceived() method but it only works if the app is in foreground. Is there something that will execute

What is it exactly and how can I get that token? 回答1: What is it exactly? An FCM Token, or much commonly known as a registrationToken like in google-cloud-messaging. As described in the GCM FCM docs: An ID issued by the GCM connection servers to the client app that allows it to receive messages. Note that registration tokens

问题 I have read a similar question on SO, however, I was not able to get the correct answer from it. I have a system wherein we send notification to around 500 devices. Unfortunately, many of these devices are not receiving the notification. I have found that OPPO F1 series phones are particularly not getting the notification. I have observed that this occurs if the app is stopped from multi-task tray. How do I resolve this? Update: I have observed that when I close the app from task-tray, my app
