Stale Google Nearby notifications - android-notifications

I had a Beacon registered to Google Nearby and then created a new notification. I got these notifications just fine. Later, I deleted the old notification and created a newer notification for the same beacon. However, I still keep getting the same old notification (that doesn't exist anymore for the beacon) in addition to the new notification. I verified this again and again on the Google Beacon Dashboard that the old notification does not exist for the beacon. Where is this stale data coming from even though I see no evidence of the old notification's existence in the Beacon dashboard? Is this a known bug in Google Nearby Notifications?

There's a bug for on device caching that previously saw the attachment from that beacon. Other devices nearby that haven't seen the old attachments will not see them.
The bug is already fixed in our dev environment and will roll out in a later release.

Detect Huawei app is uninstalled from phone

I'm having difficulty figuring out if the user has deleted my app from their Huawei phone when sending a Push.
I'm looking at the push docs, I do not see any error code for this case. Also, looking at the sample app that Huawei has given, I can't see it there either.
Does anyone know exactly what I need to look for when sending a push to Huawei to detect if an app is deleted from the phone?
One gets posted a receipt state with value 2, when the app isn't installed anymore.
If the app does not exist after the message is successfully sent to the device, the app has been uninstalled.
My ReceiptStatus.php would feature these values, but not yet implemented.

Firebase sends push notifications every day without active campaigns

A week ago I experimented with FCM console and sent push messages to my Android device. But after that many (thousands) of users started to receive pushes every day in 23 h. I suppose, this is because of time zone difference. When I look at Cloud Messaging Reports, I see it really sends data notifications. But I even don't have active campaigns (including planned campaigns). How can it be?
UPDATE
I've got answers from Firebase and AppMetrica (an alternative analytics service) support. They say it is possible the app is not able to handle the data message (silent notification) sent.
I saw charts in FCM Reports, showing that every day it delivers data messages. Every day it's count slowly raised.
I've got answers from Firebase and AppMetrica (https://appmetrica.yandex.ru/docs/). Firebase support didn't find a problem, but suspected silent push messages. AppMetrica support found a problem. AppMetrica uses FCM to send push messages. I wrote a code for integration of AppMetrica and FCM incorrectly, so silent pushes haven't been handled right. After I unselected a checkbox in settings that updated tokens via silent push messages, Firebase charts dropped to zero.

Web Push. fetching web pushes sent while offline?

I am coding a vue.js app using web pushes with Firebase Cloud Messaging and I wondered if it was possible to send a web push to a user and in case the user was offline, to somehow store it for later display when the user opens the app again. Is there a principled approach to this problem, i.e. managing web pushes when the end user is offline?
The reason I am asking this is that, so far, all the web push notifications I've committed to FCM server with tokens of offline clients (i.e. desktop browsers) went into oblivion. To be sure, FCM didn't try pushing the notification again when the clients went back online.
For this reason I am considering coding a self-made dispatcher to manage web push for offline clients, but I need to make sure my efforts are worth it.
updated: I am now able to display notifications sent to an offline client after coming back online using appropriate time_to_live values. However, only the latest notification is displayed. How is there any specific reason why?
FCM's default behavior is exactly like that. From the docs:
If the device is not connected to FCM, the message is stored until a connection is established (again respecting the collapse key rules). When a connection is established, FCM delivers all pending messages to the device.

Does Ionic 2 support private & public Firebase notifications?

I'm thinking to work on firebase notifications in the last few days but I want to some answers for this few questions:
Does Ionic2 support firebase notifications ?
Will notification show in the top of screen when my application closed or it should be work in the background ?
Is firebase notification sent on time or it may take long time ?
If I assumed Ionic 2 can send private notifications (to my device only), so can I send public notification for all application users ?
If the answer of all questions "yes", wish you give me any useful links that may help me (if you have a time)
In addition to Gabriel's answer:
The default behavior for notifications is for it to show on the top part of the screen. I haven't worked on Ionic before, but AFAIK, the behavior should compared to Android.
With that said, you should refer to the Handling Messages part of the FCM docs.
There are factors to consider that may affect the time it takes for the device to receive a message, but as FCM's behavior, it would try it's best to send the message, as soon as feasible (see my answer here).
Gonna itemize this further:
Specific device only - Yup. When sending the message, just specify the registration token(s) that should recieve that message.
All devices - Yup. You could use the Firebase Notifications Console. But if you intend to send the message by using the REST API, you have to make sure that the devices are subscribed accordingly to your custom global topic.
About the device-to-device Gabriel mentioned, I think it should be worded as server to specific device(s).
Yes it does, and it works fine with FCM (Firebase Cloud Messaging, aka GCM - Google Cloud Messaging). It supports subscribing to topics and device-to-device notification via HTTP client. The topics subscriptions and device-to-device both require FCM plugin.
Yes, they'll appear on top of your device screen as any push notification, you'll just need to code how it'll behave after receiving it, like execute something if the notification is tapped, or do something if it's received and the app is already open (foreground), it's all up to you.
It's sent on time, i've never had delay problems, the longer it took to send the notification and i receive in my device was 10 seconds. But as far as i know it "stores" your notification for 24 hours, so if the servers go down or something happen the notification has a life time of 24 hours to be sent.
You can, as said in first answer, subscribe your users to topics. Let's say you want a topic to sent message so all users can receive, you can have an all topic, or have one only for logged users, one only for users who bought products, you can even get all users tokens and send one by one, but it's much better having them subscribe to topics.
Topics notifications can be sent via the Firebase project console. Device-to-device is sent by your app code.
To send device-to-device you'll need a token, it's provided by the FCM plugin (link above) and you'll need to store this token somewhere, like in your user node on Firebase. I usualy use the user device ID provided by the Device plugin to have his token, since the user can have multiple devices and log in all then, this'll prevent token overriding.
I don't know good tutorials about configuring FCM with Firebase, if i find something i'll edit the question and add it for you, but stick to the ionic native link and the FCM plugin github page.
Hope this helps.

How to View Firebase Notification Delivery Reports?

We use Firebase to send push notifications to both Android and iOS devices. We use Http (not XMPP).
How to get delivery reports for push notifications? We want to check if a push is delivered to devices (both Android and iOS).
I cannot see any stats or reports in Firebase console.
Please help.
As seen in the Possible Duplicate Post I linked, there is currently no available reports for FCM, other than what can be seen in the Firebase Console (if you sent the message using the console) and using the Diagnostics/Statistics tool in your Play Dev Console.
There is no API that retrieves these FCM log details as of the moment. However, there's been a recent improvement in the Firebase Notifications console where stats (sent count only for now) for messages sent using the FCM API is included in the Firebase Notification console stats. From my answer in the similar post:
As of August 2018, stats for messages sent using the FCM API are now visible from the console. From the Cloud Messaging section, click on the Reports tab. From there, you will be able to filter by message type (notification, data, and all)
It would seem that the Impressions and Opens are still only available for messages sent using the console. But Sends for sure now counts the messages sent using the FCM API.
Reference: https://firebase.googleblog.com/2018/08/in-app-messaging-crashlytics.html
Our findings: In order to view statistics for Data messages, the data messages will need to include an analytics label. Check to make sure that these are included. It is just a label, https://firebase.google.com/docs/cloud-messaging/understand-delivery#adding-analytics-labels-to-messages so even without the analytics label, the message should still be sent. It just won't be tracked by their reporting. Data messages do not automatically generate a notification though. Different app states and message types will have different message receiving behavior. A data message should be received in onMessage or setBackgroundMessageHandler for JavaScript clients. Try checking these callbacks to see if the message is received there. I'd highly recommend checking out the quickstart, which should be working fine. You can use it as a base to build off or reference to compare with your app to identify potential problem areas. So our understanding is that it needs to be handled properly on the mobile end, https://firebase.google.com/docs/cloud-messaging/js/receive (though this is the javascript client, it will still apply to mobile).
You can rather go to the Google cloud console to check messages sent.
Select period from available options on top right of the page.

The delivery report added to the FCM:
Received (available only on Android devices) — The data message or notification message has been received by the app. This data is available when the receiving Android device has FCM SDK 18.0.1 or higher installed.
