Firebase on Android - I want to disable firebase notifications on Android client

Question

I'm using Firebase console to send notifications to users. However I want to let users disable notifications. How can I disable them?

I am able to handle (and stop) notifications through FirebaseMessagingService only when the app is in foreground. But I cannot stop notifications when the app is in background.

Answer 1

Not sure why this happens to you (code snippet maybe?), but there is a heavy weight ultimate solution: define your own c2dm receiver in the manifest and set the priority high (>0) then stop the notification from processing.

GCM messages are processed as ordered broadcasts, so you can stop the processing chain by calling this method:

https://developer.android.com/reference/android/content/BroadcastReceiver.html#abortBroadcast()

If you don't do anything in your receiver then the next receiver will do the processing, which will be the Firebase receiver.

Please note: Firebase is sending push notification for Remote Config changes. So, if you use Remote Config then it is not advisable to suppress any data push.

I couldn't comment yet, but racs' comment helped me a lot.

Actually, Firebase docs recommend to use data push instead of notifications if you want to have complete control over how it is handled: firebase.google.com/docs/cloud-messaging/… - quote: "Use notifications when you want FCM to handle displaying a notification on your client app's behalf. Use data messages when you want your app to handle the display or process the messages on your Android client app..."

So basically, I changed the body for the push notification request from:

{
   "data": {
       "type" : "mytype"
    },
    "notification": {
        "title": "My Title",
        "body": "My Notification Message"
    },
    "to": "/topics/all"
}

To:

{
   "data": {
       "type" : "mytype",
       "title": "My Title",
       "body": "My Notification Message"
    },
    "to": "/topics/all"
}

Now my app calls onMessageReceived() everytime even in background, and I just changed the methods to use the obtained notification title and message in the push data.

I meet the same question. I use subscribeToTopic API to subscribe the notification.

FirebaseMessaging.getInstance().subscribeToTopic("APP");

And I find the other API unsubscribeFromTopic to unsubscribe.

FirebaseMessaging.getInstance().unsubscribeFromTopic("APP");

Maybe it would be useful for APP using topic notification. It would not receive notification in foreground and background.

I had this problem.and solved by use below code:

Enable Firebase Notifications:

FirebaseInstanceId.getInstance().getToken();

Disable Firebase Notifications: deleteInstanceId() is a blocking call. It cannot be called on the main thread.

FirebaseInstanceId.getInstance().deleteInstanceId();
