Using FirebaseAdmin

After adding channelid in server code, push message popup in foreground.

Before

var message = new Message()
{
    Token = deviceToken,
    Notification = new Notification
    {
        Body = body,
    },
};

After

var message = new Message()
{
    Token = deviceToken,
    Android = new AndroidConfig
    {
        Notification = new AndroidNotification
        {
            ChannelId = "my-channel",
            Body = body,
        },
    },
};

In react native APP, pass "notification.payload" back to postLocalNotification function. It is "notification.payload". Not "notification".

Notifications.events().registerNotificationReceivedForeground((notification, completion) => {
  if (Platform.OS == 'android') {
    Notifications.postLocalNotification(notification.payload);
  }

  completion({alert: true, sound: true, badge: false});
});

The channel ID is set by setNotificationChannel

Notifications.setNotificationChannel({
  channelId: 'my-channel',
  name: 'My Channel',
  importance: 5,
  description: 'My Description',
  enableLights: true,
  enableVibration: true,
  groupId: 'my-group', // optional
  groupName: 'My Group', // optional, will be presented in Android OS notification permission
  showBadge: true,
});
