Images are not displayed on devices (both iOS and Android) when sending notifications with FCM. I set the image URL using the Notification Builder.
List<String> fcmTokens = List.of(...); Notification notification = Notification.builder().setTitle("Hello").setBody("world").setImage("https://e-cdns-images.dzcdn.net/images/cover/f2d3db07f3f045a048cdacf53b5cf9dd/250x250-000000-80-0-0.jpg").build(); MulticastMessage message = MulticastMessage.builder() .setNotification(notification) .addAllTokens(fcmTokens).build(); BatchResponse response = FirebaseMessaging.getInstance().sendMulticast(message);
Note that I receive the notification on the devices, only the image is not displayed. I am able to see the image in the notification when sending it using the Firebase Console.
When investigating the issue, I discovered that other SDKs use imageUrl instead of image attribute. For example, for NodeJS: https://firebase.google.com/docs/reference/admin/node/firebase-admin.messaging.notification.md#notificationimageurl
imageUrl
image
The Java SDK still uses the image key instead of imageUrl: https://github.com/firebase/firebase-admin-java/blob/master/src/main/java/com/google/firebase/messaging/Notification.java#L33
I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
Getting similar error. Images sometimes gets displayed and sometimes not. Any solution??
