Firebase RemoteMessage has filled Bundle but getData() is empty

Question

My firbase RemoteMessage has a mBundle with 12 key value pairs, according to debugger, those field were filled .

But when I say: remoteMessage.getData(); the resulting ArrayMap Map<String, String> has size 0 and thus no elements.

How can I access the Map of remoteMessage?

Answer 1

I know this might be late but You can get the data from Notification Object in RemoteMessage

String title = remoteMessage.getNotification().getTitle();
String body = remoteMessage.getNotification().getBody();

hope this helps

I also encountered same problem.
And finally fixed this problem.
In my case, server side's sending FCM payload problem.
like this.

options = {
  priority: 'high',
  notification: {
    title: "title",
    body: "message",
    url: "some_url",
    image_url: "some_image_url"
  }

And I updated like following,

options = {
  priority: 'high',
  notification: {
    title: "title",
    body: "message",
  },
  data: {
    url: "some_url",
    image_url: "some_image_url"
  }

After that, I could get payload values by remoteMessage.getData().
