Not receving Firebase Cloud Messaging When App Is Completely Closed(Killed mode)

[SK Suman]

it's regarding android push notifications.
It's working fine for the Android version lower than oreo(API level 26 ). But above oreo (API level 26 ), the push notifications are not coming when the app is closed. 

I've followed the steps given in the firebase documentations:--

https://firebase.google.com/docs/cloud-messaging/android/first-message

PFA the code used by me for your reference.

Please help with a solution to this issue, provide documentation if available.

Looking forward to hearing from you soon.

Thanks & Regards,

SK SUMAN

You need to assign the notifications to a notifications channel:

> Starting in Android 8.0 (API level 26), all notifications must be assigned to a channel or it will not appear.

Furthermore, have a look at the notification importance settings: https://developer.android.com/guide/topics/ui/notifiers/notifications.html#importance
