firebase-cloud-messaging

问题 I am implementing Firebase messaging in my app. While I am testing the app sends the refreshed_token to my database, but in live production environment (Play store) it returns 'BLACKLISTED' as push_token. Does someone know why this happen? Or what I can do to fix this problem. Can't find others with the same problem. I use the code from the Firebase documentation. @Override public void onTokenRefresh() { super.onTokenRefresh(); String refreshedToken = FirebaseInstanceId.getInstance().getToken

问题 When do FCM tokens expire? Is it at 6 months? 回答1: It doesn't expire though. It renews itself if one of the following happens. According to https://firebase.google.com/docs/cloud-messaging/android/client: -The app deletes Instance ID -The app is restored on a new device -The user uninstalls/reinstall the app -The user clears app data. Monitor token generation The onTokenRefreshcallback fires whenever a new token is generated, so calling getToken in its context ensures that you are accessing a

问题 After I tested the push notifications are working with Postman I'd like to send a push request to FCM when I am sending a message in my app. The function called is going to my Java server and call a function like : @POST @Consumes(MediaType.APPLICATION_JSON) public Response sendMsg(Message m) throws ExceptionFacade { ... } So each time I call this function I'd like to send a POST request to https://fcm.googleapis.com/fcm/send with a json. I want to know if there is already a code ready for a

问题 I still new with firebase and android notifications. I want to be able to send notifications to a single user based on some rules. What I've been reading so far is that a token can be generated with: FirebaseInstanceId.getInstance().getToken() Then, the token will need to be refreshed at some point when it expires. How to I set expiry for these tokens, if at all possible? If there are a thousand users having their tokens refreshed around the same time then I will need to do a thousand writes

问题 I am aware that I can supply registration_ids to the JSON request to send to multiple devices in the form of string arrays. However, I have a unique token that I want to send to each of those registration_ids . How can I achieve that without simply looping the send request for the number of devices I wish to send to: registration_ids: [1,2,3,4,5] data: { //if id==1, include the necessary token I wish to include. } 回答1: Unfortunately, if you are attempting to send something unique to each user

问题 I was trying to write an application using Firebase Cloud Messaging as per the guidelines given here, but I'm struck in adding the dependency for implementing FCM (com.google.firebase:firebase-core:9.0.2). Every time I try to add it via project structure, it won't list the dependency in the search results. When I try to add it in app level gradle, it gives me an error that the dependency cannot be resolved. I don't know where I'm going wrong but please help me out with this. 回答1: Download

问题 ![enter image description here][1] If I send push message by selecting a package from Firebase console, the push goes to all devices, but during sending to individual device, it displays the error: Invalid reg token,please check token format Error Snapshot: [ ][1] 回答1: UserID in console is not the registration token for Firebase messaging. By Firebase docs: on initial startup of your app, the FCM SDK generates a registration token for the client app instance. If you want to target single
