FCM push message not receiving in Oreo

Question

I have implemented FCM. The messages are receiving in Android N and lower devices.

dependency

implementation "com.google.firebase:firebase-messaging:17.1.0"

I have tried sending messages from firebase console. It showing in Android N but not in Android O.

I have tried sending data notification from the server. Didn't got any call on onMessageReceived() in Android O.

Added channel while showing notification

 val notificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager

    // Since android Oreo notification channel is needed.
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        val channel = NotificationChannel(channelId,
                "CRW notification channel",
                NotificationManager.IMPORTANCE_HIGH)
        notificationManager.createNotificationChannel(channel)
    }

    notificationManager.notify(0 /* ID of notification */, notificationBuilder.build())

I have checked this in Samsung S2 and One plus 6.

Do I need to do anything extra for Android O other than setting notification channel on showing the notification?

have u check this **[Notification not showing in Oreo](https://stackoverflow.com/questions/43093260/notification-not-showing-in-oreo)** — AskNilesh, Jul 25 '18 at 06:44

Did you set your FCM to high-priority.

Add this to your message body:

{
  ...
  "priority":"high"
  ...
}

High priority. FCM attempts to deliver high priority messages immediately, allowing the FCM service to wake a sleeping device when necessary and to run some limited processing (including very limited network access). High priority messages generally should result in user interaction with your app. If FCM detects a pattern in which they don't, your messages may be de-prioritized.

Ref: https://firebase.google.com/docs/cloud-messaging/concept-options#setting-the-priority-of-a-message

Check this on server side the push message is sent as Data Payload or Notification For android version greater than M it requires to send notification in Data Payload By passing send Data (on server side). Also works when app is running in background.

The notification sent as Data payload. This is working as expected (both background and foreground) in Android L, M, and N. – Suneesh Ambatt Jul 25 '18 at 06:52
Check if this issue only the case in background – LadyEinstien Jul 25 '18 at 06:59
I suggest you to send both notification and data payload { "message":{ "token":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...", "notification":{ "title":"Portugal vs. Denmark", "body":"great match!" }, "data" : { "Nick" : "Mario", "Room" : "PortugalVSDenmark" } } } – LadyEinstien Jul 25 '18 at 07:01
