How to set custom layout for those notifications which will be shown when app is in background?

Question

I implemented the firebase cloud messaging (FCM) service in my app and I get notifications with my custom layout but just when the app is in the foreground and the reason is clear, It is because of existing setCustomContentView(myContentView) in onMessageReceived and we all know that onMessageReceived handle notification just when the app is in the foreground.

Now, I'm going to know is there a way to set the same custom layout for the notifications which will be shown when the app is in the background?

Use data payload instead of notification payload which works for both foreground and background. — Piyush

FCM has two messages types: when your app is in the background.

Notification message:
Data message:
1. Notification message: the notification is delivered to the device’s system tray, not onMessageReceived
2. Data message: always, the notification is delivered to onMessageReceived

so, You should send a format is Data Message to handle notification in onMessageReceived when the app is background or foreground

I would advise to modify server code to receive data onMessageReceived in both foreground and background and ask sender to send only data payload without notification.

Here I have removed notification payload.

{"to":"[add your token]","data":{"title":"Working Good","body":"[add your message]"},"priority":"high"}
