Push notification not working on Android 7.0 (FCM) with release-apk

Question

My android app is live on the store and its push notification stopped working suddenly on > 7.0 android os.

Dependencies :

'com.google.firebase:firebase-core:10.2.0'    
'com.google.firebase:firebase-messaging:10.2.0'

Notification builder code :

NOTIFICATION MANAGER :

   public void createNotificationManager(){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

            notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
            String id = "projectname";
            // The user-visible name of the channel.
            CharSequence name = "projectname";
            // The user-visible description of the channel.
            int importance = NotificationManager.IMPORTANCE_MAX;
            NotificationChannel mChannel = new NotificationChannel(id, name, importance);
            // Configure the notification channel.
            mChannel.enableLights(true);
            mChannel.setLightColor(Color.RED);
            notificationManager.createNotificationChannel(mChannel);

        }else{
            notificationManager =
                    (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        }
    }

NOTIFICATION BUILDER :

                NotificationCompat.Builder notificationBuilder = new
                        NotificationCompat.Builder(this);
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                    notificationBuilder.setSmallIcon(R.drawable.ic_launcher_transparent);
                } else {
                    notificationBuilder.setSmallIcon(R.mipmap.ic_launcher);
                }
                notificationBuilder
                        .setContentTitle("Projectname")
                        .setStyle(new NotificationCompat.BigTextStyle()
                                .bigText(intent.getStringExtra("gcm.notification.body")))
                        .setContentText(intent.getStringExtra("gcm.notification.body"))
                        .setAutoCancel(true).setDefaults(Notification.DEFAULT_SOUND).setSound(soundUri)
                        .setContentIntent(pendingIntent).setVisibility(NotificationCompat.VISIBILITY_PUBLIC);

createNotificationManager();
notificationManager.notify(id, notificationBuilder.build());

In debug apk it is working i checked but with the production (release_apk) it is not showing notification.

Please help in this.

it is the issue of notification Chanel . you have to create notification Chanel to retrieve notifications — Jay Thummar, May 31 '18 at 09:28
Jay Thummar , I have already created the notification Chanel for the Oreo (8.0) version. But for 7.0 it is not needed right. also in the debug build it is working fine. Still it could be the issue ? — Parvindra Singh, May 31 '18 at 09:33
share your notification builder code and service that you have written. — Aniruddha K.M, May 31 '18 at 09:34

@ParvindraSingh the issue is because you have not passed the channel in the notification builder — Aniruddha K.M, May 31 '18 at 10:02
@war_Hero this code is working in the debug build , not working in the release build. I think it is not code issue. Still it might be ? — Parvindra Singh, May 31 '18 at 10:11

Ensure that you have added the SHA1 of your release certificate into the Project Settings/General page for your Firebase project.

For each app you can add multiple SHA1's and you should include both your debug and release certificates.

Try to replace:

'com.google.firebase:firebase-core:10.2.0'    
'com.google.firebase:firebase-messaging:10.2.0'

With latest update (based on this url):

implementation 'com.google.firebase:firebase-core:16.0.0'
implementation 'com.google.firebase:firebase-messaging:17.0.0'

And make sure that you are using google play services in latest version too:

classpath 'com.google.gms:google-services:4.0.1'

From the code it is evident that the NotificationChannel that you have created is not passed into the NotificationCompat.Builder hence you are facing this issue, you can read about it from the docs here. Here is an example of the notification given by google. If you want to read more about this refer the docs.

Hi war_hero , i have another problem that if app is killed state then notifcation not recieving in android 8.0 (Oreo) – Parvindra Singh Jun 08 '18 at 08:42
oh, 1)in onMessageReceived have you put any condition checking for login state. 2)are you deleting the device token by any chance – Aniruddha K.M Jun 08 '18 at 08:48
Yes, it is working fine in < 8.0 if app i killed , I have found that it is not possible to use FCM notifications if app is killed in 8.0 check the link : https://github.com/firebase/quickstart-android/issues/378 – Parvindra Singh Jun 08 '18 at 09:24
how i can share you the service code , you need full code ? or which part you need ? I am still not find an solution for 8.0 android kill state notifications. – Parvindra Singh Jun 18 '18 at 11:09
