I am working in react native project where I required to have push notification from server to be implemented in my app. I tried to use firebase as the notification provider. For that, I used react-native-firebase package. I tried this example link Its working fine when the app is running. But notification failed to come when the app is closed. So how can I achieve this

Not For Only Firebase
some Android devices cannot receive push notifications when the app is closed. The app can receive push notifications when it is running, either in the foreground or in the background.
Cause
On these devices most of the apps are not permitted by default to be awaken in the background. This way the app cannot process the received push notification when it is not running.
Currently, this behavior is identified only on devices from the following manufacturers:
- Huawei
- Xiaomi
- Asus
Solution
You need to modify certain settings on your device.
Huawei devices
Open Settings → Protected Apps
Place your application in the list
Xiaomi devices
On the app screen tap on the Security app Select Permissions → Autostart Locate your app in the list and enable "Autostart" Restart the device
Asus devices
Locate the Auto-start Manager as noted here Locate your app in the list and enable "Allow"

Hi @Anuj there are two types of notification in firebase, notification and data payload . If you send as Notification it will work only when app is in foreground , ask backend team to send notification as data payload you have to set notification payload as null Check Here
