Firebase cloud messaging notification not received by device

Question

I am having an issue with FireBase Cloud Messaging in which I get the Token from the device and send the notification test through the Google Firebase notification console however, the notification is never logged nor pushed to the android virtual device. The documentation for FCM is almost exactly the code that I have below and little else in the way of what else you would have to do to get push notifications working with firebase. I have gone through all of the setup information (build.gradle additions, Installing google play services, etc...) as specified in the documentation but still do not have messages generating. I do receive a one-time error immediately after pushing the notification that states "I/FA: Tag Manager is not found and thus will not be used" but that is the only data that is output and I did not find anything related to Tag Manager requirements and FCM on the googles. What is wrong with the code that I am not receiving my push notifications to the logcat or the device? Please let me know any further information that would be helpful. Thanks.

NotificationGenie.java

public class NotificationGenie extends FirebaseMessagingService {

private static final String TAG = "Firebase_MSG";

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    // TODO(developer): Handle FCM messages here.
    // If the application is in the foreground handle both data and notification messages here.
    // Also if you intend on generating your own notifications as a result of a received FCM
    // message, here is where that should be initiated. See sendNotification method below.
    sendNotification(remoteMessage.getNotification().getBody());
    Log.d(TAG, "From: " + remoteMessage.getFrom());
    Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
}

private void sendNotification(String messageBody) {
    Intent intent = new Intent(this, PostLoginActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);

    Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.tf2spyprofile)
            .setContentTitle("FCM Message")
            .setContentText(messageBody)
            .setAutoCancel(true)
            .setSound(defaultSoundUri)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

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

}

"You must also keep in mind that to receive Messages sent from Firebase Console, App must be in background, not started neither hidden." --- According to @Laurent Russier's comment.

I never got any message from Firebase, until i put my app in the background.

This is true only on usb connection for emulator you get notification in foreground as well

No, you need to make sure your app is on background to get a Notification message from console – Tosin Onikute Oct 24 '16 at 07:21
You can test using http://pushtry.com easier than Firebase console. You can also send custom JSON. – Arvind Dec 29 '16 at 11:13
Thanks @HtmlTosin! It worked for me too on the App that I am migrating from GCM to FCM.

You have placed your service outside the application tag. Change bottom to this.

<service

    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT"/>

This worked for me. Actually, I was finding that I was only receiving notifications when my app was running. If I restarted the phone, notifications wouldn't come through. But after setting the `enabled` and `exported` attributes, the push notifications come through fine now. Thanks, Hoby! :-) – ban-geoengineering Sep 05 '16 at 21:51

I think it would probably be a good idea to add the same two attributes to your `MyInstanceIDListenerService` service, too. – ban-geoengineering Sep 05 '16 at 21:53

Not necessary. Tried Firebase Sample Messaging Project - with and without "enabled" and "exported" - it's excessive. Helped running and hiding app to see notification at topbar - see Html Tosin's answer. – Zon Jul 12 '17 at 06:04

As per android docs enabled is `true` by default and exported means if service can be invoked by components external to the app. Not sure why this is necessary here. https://developer.android.com/guide/topics/manifest/service-element#exported – Adi Oct 06 '19 at 06:54
Worked for me too! Tutorial I watched had "exported=false", it worked when I changed to true :) – Sam Chahine Jul 31 '22 at 10:42

I faced the same issue of Firebase cloud messaging not received by device.

In my case package name defined on Firebase Console Project was diferent than that the one defined on Manifest & Gradle of my Android Project.

As a result I received token correctly but no messages at all.

To sumarize, it's mandatory that Firebase Console package name and Manifest & Gradle matchs.

You must also keep in mind that to receive Messages sent from Firebase Console, App must be in background, not started neither hidden.

What do you mean when you say "not started neither hidden"? – Gilbert Apr 27 '20 at 14:02
That's a typo. That app has to be running but in the background. If you have the app currently open when the push notification comes in the OS will not display it. – d512 Apr 26 '23 at 01:53

In my case, I noticed mergedmanifest was missing the receiver. So I had to include:

 <receiver
            android:name="com.google.firebase.iid.FirebaseInstanceIdReceiver"
            android:exported="true"
            android:permission="com.google.android.c2dm.permission.SEND" >

I had a similar problem, but in my case I was missing the google-services plugin from my Gradle build (I was adding Firebase to an existing project).

I added the following to my root build.gradle:

classpath 'com.google.gms:google-services:3.1.0'

and the following to the end of my app-level build.gradle:

apply plugin: 'com.google.gms.google-services'

I then had to download the google-services.json file from the Firebase Console (having originally imported an existing Google Cloud project) and copy it to my app directory`.

If you have just added FCM to an existing app, onTokenRefresh() will NOT be called. I got it to run by uninstalling the app and installing it again.

After spending hours on this issue I finally realised the problem when I intentionally corrupted the format of the "google-services.json" and my build still succeeded. My IDE(AndroidStudio) does not notice the changes in this file. I tried many things, "reload from disk", gradle task "cleanBuildCache", new virtual device, uninstalling/reinstalling the app etc but none worked.

For me the solution was in AndroidStudio -> Build -> Clean Project and Build -> Rebuild Project

PS: Also make sure "google-services.json" is in the "app" folder.

As if you want your app to run in > 24 versions too, follow these:

1.Add this in your strings.xml

< string name="default_notification_channel_id" translatable="false"> fcm_default_channel

Add this meta-data in your manifest file:

< meta-data android:name="com.google.firebase.messaging.default_notification_channel_id" android:value="@string/default_notification_channel_id" />

3.for creating notifications (with images) use this method where you are handling notifications, if directly then add in the firebasemessaging service or if you are using some util class then add in that util class :

   @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN)
    public static void createBigNotification(Bitmap bitmap, int icon, String message, Uri alarmSound) {
        final int NOTIFY_ID = 0; // ID of notification
        NotificationManager notificationManager = (NotificationManager) mContext.getSystemService(NOTIFICATION_SERVICE);
        String id = mContext.getString(R.string.default_notification_channel_id); // default_channel_id
        String title = mContext.getString(R.string.app_name);
        Intent intent;
        NotificationCompat.Builder builder;
        if (notificationManager == null) {
            notificationManager = (NotificationManager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);
        }
        PendingIntent resultPendingIntent;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            int importance = NotificationManager.IMPORTANCE_HIGH;
            NotificationChannel mChannel = notificationManager.getNotificationChannel(id);
            if (mChannel == null) {
                mChannel = new NotificationChannel(id, title, importance);
                mChannel.enableVibration(true);
                mChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
                notificationManager.createNotificationChannel(mChannel);
            }
            builder = new NotificationCompat.Builder(mContext, id);
            intent = new Intent(mContext, MainActivity.class);
            intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
            resultPendingIntent = PendingIntent.getActivity(mContext, 0, intent, 0);
            NotificationCompat.BigPictureStyle bigPictureStyle = new NotificationCompat.BigPictureStyle();
            bigPictureStyle.setBigContentTitle(title);
            bigPictureStyle.setSummaryText(Html.fromHtml(message).toString());
            bigPictureStyle.bigPicture(bitmap);

            builder.setContentTitle(title)        // required
                    .setSmallIcon(R.drawable.app_icon)   // required
                    .setContentText(message) // required
                    .setDefaults(Notification.DEFAULT_ALL)
                    .setAutoCancel(true)
                    .setSound(alarmSound)

        }
        Notification notification = builder.build();
        notificationManager.notify(NOTIFY_ID, notification);
    }

Follow these steps and your notification will come in the notification tray.

Where do you put the createBigNotification method from and where do you call it from? — Gilbert, Apr 27 '20 at 15:38
@Ssenyonjo you can add it in your broadcast receiver or the Activity/Fragment file which you will access globally in the app. — amit pandya, Apr 28 '20 at 06:08

In my case, I manually killed some google play services and forgot about it.

Later, I have to restart the device, after that I can receive notification without any problem.

2 mistakes that I had to correct, after which the issue was resolved.

Referring to the official documentation gave this nice snippet which helped confirm the Subscription status.

 Firebase.messaging.subscribeToTopic(TOPIC)
                    .addOnCompleteListener { task ->
                        var topicSubscriptionStatus = "Subscribed"
                        if (!task.isSuccessful) {
                            topicSubscriptionStatus = "Subscribe failed"
                        }
                        Log.d(TAG, topicSubscriptionStatus)
                        Toast.makeText(baseContext, topicSubscriptionStatus, Toast.LENGTH_SHORT).show()
                    }

my topic name had a typo "/topic/" instead of the correct one "/topics/". Right after correcting this the service started receiving the messages
I had to add the flag "FLAG_IMMUTABLE" on the PendingIntent (error in logcat mentioned this is needed from S)

I followed all the steps according to the firebase website to set up sending notifications for Android APPs. I tried many times but I can't received the notifications no matter on virtue device or physical device. After I changed some settings(those settings about receiving notifications in the SETTING section ) in virtue device and physical device, both virtual and physical devices started receiving notifications.
