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.

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.

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 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();

You can handle all push events from all difference services (with Firebase). First create YouUniversalFCM extends WakefulBroadcastReceiver

For example:

public class YourUniversalFCM extends WakefulBroadcastReceiver {

    private static final String ACTION_REGISTRATION
        = "com.google.android.c2dm.intent.REGISTRATION";
    private static final String ACTION_RECEIVE
        = "com.google.android.c2dm.intent.RECEIVE";

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        for (String key : intent.getExtras().keySet()) {
            Log.d(
                    "TAG",
                    "{UniversalFCM}->onReceive: key->"
                            + key + ", value->" + intent.getExtras().get(key)
            );
        }
        switch (action) {
            case ACTION_REGISTRATION:
                // TODO: 2016-08-06
                break;

            case ACTION_RECEIVE:
                // TODO: 2016-08-06
                break;

            default:
        }

        abortBroadcast();
    }
}

Next in AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WAKE_LOCK"/>

<application
    ...>

    ...

    <receiver
        android:name=".fcm.receivers.UniversalFCM"
        android:permission="com.google.android.c2dm.permission.SEND">
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE"/>
            <action android:name="com.google.android.c2dm.intent.REGISTRATION"/>
            <category android:name="YOUR_PACKAGE"/>
        </intent-filter>
    </receiver>

</application>

Replace YOUR_PACKAGE by the package of your app. That's all. If you want to subscribe for another push service, you must be add YourTokenService

public class YourTokenService extends FirebaseInstanceIdService {
    @Override
    public void onTokenRefresh() {
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
        L.d(TokenService.class, "onTokenRefresh() Refreshed token: " + refreshedToken);
        // TODO: 2016-08-06
        super.onTokenRefresh();
    }
}

And declared in AndroidManifest.xml

<service android:name="YourTokenService">
    <intent-filter>
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
    </intent-filter>
</service>

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.
