How to make onNotificationOpenedApp() work with custom FirebaseMessagingService?

[rgbedin]

First of, thanks for dedicating code to our community.

In my application I implement a custom FirebaseMessagingService -- all messages that are sent via push to the client are encrypted. Therefore I need to intercept all pushes to be able to decrypt the notification body and title. Everything works fine: I am able to receive the message on the onMessageReceived() method. I then decrypt and create a new local notification:

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    if (remoteMessage.getData().size() > 0) {
        try {
            JSONObject jsonObject = new JSONObject(remoteMessage.getData());
            displayCustomNotification(jsonObject.getString("title"), jsonObject.getString("body"));
        } catch (JSONException err) {
            err.printStackTrace();
        }
    }
}

@RequiresApi(api = Build.VERSION_CODES.N)
public void displayCustomNotification(String title, String body) {
    boolean isOnForeground = foregrounded();

    if (isOnForeground) {
        return;
    }

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

    Long tsLong = System.currentTimeMillis()/1000;
    int timestamp = Math.toIntExact(tsLong);

    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    Intent intent = new Intent(this, MainActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 1251, intent, PendingIntent.FLAG_ONE_SHOT);
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    int importance = NotificationManager.IMPORTANCE_HIGH;
    String channel = "channel";

    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, channel);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        if (mChannel == null) {
            mChannel = new NotificationChannel(tauriaChannel, title, importance);
            mChannel.setDescription(body);
            mChannel.enableVibration(true);
            notificationManager.createNotificationChannel(mChannel);
        }

        notificationBuilder
            .setContentTitle(title)
            .setSmallIcon(R.drawable.ic_tauria_notification)
            .setContentText(bodyWithKey)
            .setDefaults(Notification.DEFAULT_ALL)
            .setAutoCancel(true)
            .setContentIntent(pendingIntent)
            .setSound(defaultSoundUri);

        notificationManager.notify(timestamp, notificationBuilder.build());
    } else {
        notificationBuilder
            .setContentTitle(title)
            .setContentText(bodyWithKey)
            .setAutoCancel(true)
            .setColor(ContextCompat.getColor(getBaseContext(), R.color.black))
            .setSound(defaultSoundUri)
            .setSmallIcon(R.drawable.ic_tauria_notification)
            .setContentIntent(pendingIntent)
            .setStyle(new NotificationCompat.BigTextStyle().setBigContentTitle(title).bigText(body));

        notificationManager.notify(timestamp, notificationBuilder.build());
    }
}

The notification is successfully displayed to the user, even if the app is on dead state. I also receive the callback from messaging().setBackgroundMessageHandler() just fine. My issue is that I am trying to detect if the user tapped the notification to open the app, but neither the onNotificationOpenedApp() or messaging().getInitialNotification() is triggered.

Moreover, these listeners do work fine if I just send a notification with a "notification": { "title": "test" }"; however that makes the OS to not pass that through my custom FirebaseMessagingService and display rightaway to the user.

I tried digging into the source code and I realized that maybe my custom FirebaseMessagingService was not setting some expected properties inside the intent that I am creating. Therefore I tried adding the following code, but with no success as well:

intent.putExtra("launchedFromNotification", "true");
intent.putExtra("messageId", "0:2615498316804087%40f8bc8040f8bc80");
intent.putExtra("message_id", "0:2615498316804087%40f8bc8040f8bc80");
intent.putExtra("collapseKey", "com.myapp.mobileapp");
intent.putExtra("from", "329957935616");
intent.putExtra("sentTime", "1615499164445");
intent.putExtra("google.message_id", "0:3615498316804087%40f8bc8040f8bc80");
intent.putExtra("gcm.n.e", "1");
intent.putExtra("gcm.notification.e", "1");

Does anyone have any insight on how I can make my custom created notification being able to be detected by the onNotificationOpenedApp() callback?

Thank you!

An I am still facing the same issue. Any help is appreciated!
