Android: How do I find Id/modify/dismiss a notification from FCM loud push

Question

We're trying to migrate from silent FCM pushes to loud ones (i.e. from "data":{} managed by the app, to those that "notification": {} causes). With loud push, FCM client framework automatically creates a notification. Therefore:

• I don't have its ID so I can modify it
• I can't control its channel ID (which is important starting Oreo).
• Not sure if there is a way for my server to request a specific notification sound for it (the same way they do in iOS). Actually, I can do that from onRemoteMessage() but the auto generated notification plays the default beep, which will cause a funny playing of both sounds.

How can I solve those issues?

Thanks

In case of notification payload when FCM client framework automatically creates a notification using notification payload data. Notification payload contains a key for sound so you have to set it from server side.

For Example :

{
    "to" : "yourToken",

    "notification" : {
      "body" : "Notification Body",
      "title" : "Notification Title",
      "sound" : "/res/raw/yourSoundResourceFile"
    }
  }   

As per as firebase documentation sound is a Optional string

Supports "default" or the filename of a sound resource bundled in the app. Sound files must reside in /res/raw/.
