Firebase Expandable Notification Show image when app is in background

Question

I am implementing FCM notifications in Android, but how does notifications differ depending on the app status (background vs. foreground)?

Answer 1

'Data' key needs to be there in Push Notification bundle.

In addition to above answers, If you are testing push notifications using FCM console, 'data' key and object is not added to Push Notification bundle. So you will not receive detailed push notification when App is background or killed.

In this case you have to opt for your back end admin console to test App background scenario.

Here, you will have added 'data' key to your push bundle. so, detailed push will be shown as expected. Hope this helps few.
