title: Custom sound in Firebase push notification
body: <p>I am sending push notification from Firebase to my Android application, but it is only playing the default sound when the notification is recieved.</p>
  
  <p>I have set the custom sound param <code>{“sound”:”notificationsound.mp3”}</code> in the fcm notification object and the file is present in the res/raw folder according to (<a href="https://firebase.google.com/docs/cloud-messaging/http-server-ref" rel="nofollow noreferrer">https://firebase.google.com/docs/cloud-messaging/http-server-ref</a>)
  But It’s still playing the default sound on all app states (background, foreground and killed).
  This is my request body for sending the notification on Android :</p>
  
  <pre><code>{
  "to" : “some id”,
  "notification": {
  "title":"asdasd",
  "body":"sdsad",
  "click_action" : "MAIN",
  "sound":"notificationsound.mp3"
  },
  "data": {
  "title" : "Something",
  "body" : "Important",
  "type" : "message"
  },
  "priority": "high"
  }
  </code></pre>
  
  <p>What I can do to play the custom notification sound.</p>
