I want to send the "We miss you" notification to the users who haven't user my app in more than 5 days. Can this be done with Firebase notifications?
I haven't noticed any options when creating a new notification that can see if the app wasn't used or anything similar, so I'm wondering is it possible to retrieve the timestamp of when the app was last accessed and schedule a notification (maybe locally?) using the said timestamp?
You can use implement ActivityLifecycleCallbacks.To know how to implement refer -Automatically log Android lifecycle events using ActivityLifecycleCallbacks?
Once you implement ActivityLifecycleCallbacks you will get callback whenever any of the activity is interacted by the user.
You can send this timestamp to the server everytime user interacts with your app.
The server can maintain 5 min timeout logice and send a push notification to the device.
On receiving the push notification your app can show notification to the user.

I am developing an android app which is about meal subsciption.
I update the entire menu(breakfast, lunch , dinner) for each day in the morning( I am using firebase).
Now i want to send scheduled notification to users that is, i want to notify a user at 1pm that this is the coming menu for the lunch similarly i want to notify the user at around 8pm that this is the coming menu of dinner.
What should i use to get this scheduled notification?
I had an idea in mind that when i update the database in the morning. I will send a data payload with the required scheduling time using cloud messanging and schedule the notification on the device itself.
Will this work?
Yes, it will work, I recommend using Worker to schedule notification and take into account receiving notifications while the app is in the background, because your app should have that feature I guess.
I am using firebase for notification. I want to send notification to the group of users... If any one of them press accept notification action button then, the same notification must be remove from the other users device. Is it possible to do using firebase.
Ex. I want to send notification to 5 delivery boys for collecting parcel from XYZ place, if any of them accept the collecting parcel order notification then the same notification must be remove from other 4 delivery boys autometically.
I study and practically done an example of https://firebase.google.com/docs/cloud-messaging/android/device-group Notification send to all 5 del. boys but notification still there after accepting the collecting order.
Please, help.
Firebase Cloud Messaging has two distinct types of messages:
Notification messages that are handled and displayed by the OS when the app is not active, and handled by your application code when the app is active.
Data messages that are always handled by your application code, which can then choose to display or update UI notifications as needed.
What you're describing sounds like you want to use data messages only, and then use Android's notification UI/API to display, update, or hide a notification.
I'm building a newspaper-like app and I would like to know how many people received the article's push notification vs how many actually read it.
I was thinking to implement a way in which when the notification is received the app wakes up and send a request to the server saying "Hi I'm _____, I've received the notification of the article ____" and store it in the database. Then afterwards if the user click on the notification and goes to read the article I send another request saying "Hi I'm ____ and I've read the article _____" and I also store it on the database. Afterwards with some queries I'm able to understand the percentage read/received.
I don't understand if it's even possible to wake up the app even if it was not opened by the user in a while and send a request to the server (for background is meant that the application is not launched or that is in the cache ?).
I would like to achieve what they did with Whatsapp:
I receive a new message on Whatsapp
I don't open the app
I go to WhatsApp Web
I open the conversation on WhatsApp Web
The badge and the notification on the phone goes away because I read it somewhere else
I think that that feature is achieved with silent push notifications that just update the app badge and clear the read notification.
Thats a very nice question on how to implement such silent notifications. There are few variables here that we need to consider and deal them in a different way.
Push notifications sent to the users - Some of them would have received it, Some may not have received it at all.
Pushing multiple notifications to the same user in a small amount of time - It becomes difficult here to track the exact notification user opened the app. Because user might have read all the news that received notifications in a single attempt.
The actual content displayed to the user in the app - User might have opened the app because of notifications. Some times he might have seen the notifications and then opened the app directly without interacting with the notifications.
So this is how the implementation can be.
Implement push notifications for the app
User receives the push notifications and the notification badge shows Number (1).
Now when the user views the same news story in any other medium (Your own Mac App or PC app). Server is notified of the users action and the news he/she/whoever just read.
Now the server knows it has sent a notification and it is not read. When you receive the read notification, you can send a remote notification that can be handled by the app in background and update the badge.
Check out this link for more details on how to handle notifications in various modes.
Apple documentation also can be referred here for background mode - remote-notification.
So you will be making your app run in background with certain settings to respond to silent notifications and update the badge just like WhatsApp. I hope this helps.
I've already implemented such thing in one of my app, and it's actually tricky.
You'll have a lot of use cases to handle.
First thing (but you seem to already know it): Apple does not provide
any callback to say : "this notification was sent"
Second thing : when your app is killed (not even in background), nothing at all can be done with your notification, meaning your app won't be able to wake up and read the notification, and therefor do something. The only thing you can do is changing the badge number, even if your app is killed.
Third thing : when your app is in background, you can wake up your app during 30sec. During that time you can send a request to the server, but if it takes too long, the process will be killed by the OS.
Saying that, here is a quick explanation of how you could implement the system:
You'll need on the server side to save in your data base any notifications that were sent. As soon as they are sent, save them as "pending"
On the app side: if your app is in background, as soon as the notification is received, you can wake up your app to send a request to the server. Then in your data base, your notification status will change to "receive" or "notified". If your app was killed, when the user launch your app, send a request to the server to ask for all notification in "pending" state, that way your app will be up to date, as well as your badge number.
If the user click on the notification, this will open your app directly on the article, that way you'll be able to send a request and say to your server that the article was received and read.
If the user read your article on the web side, send a notification. Set the notification badge number with the number of actual "pending" notification in your data base.
Hope this will help you in addition of the answer of #Prav :)
try this Notification Listner service https://github.com/kpbird/NotificationListenerService-Example.

Hello Matteo,
Thank you for contacting Apple Developer Technical Support (DTS). Our engineers have reviewed your request and have concluded that there is no supported way to achieve the desired functionality given the currently shipping system configurations.
So at the end of the games IT'S NOT POSSIBLE
You want to sync your app with web app or website than once you send notification to application than set notification to particular ID.If user read that message from your web then send push notification again with different message and handle in service or broadcast receiver after that cancel notification if received message contains different message.you can also use Notification Listener.Refer thislink
Refer this link for ios.
Hi #Smile Applications after reading your question I would suggest you see OneSignal website. OneSignal will allow you to send notifications to your subscribed users. It will also show you how many users are using your app and how many of them have received your notifications. If you want to send notifications and track them from the app itself you can use their API. It is easy and I have implemented this in Android and soon will be implementing in IOS.
Now the second part of your question about knowing how to track how many users have read/opened your notification and on which activity they are on you can use Google Analytics. It will allow you to see from which part of the world your users are using your app and which activities of your app are being opened most. It is also easy and I have implemented this also in Android and soon will be implementing in IOS too.
I am trying to figure out how Facebook / Twitter sends push notifications like "You have 20 new followers"I don't know how to call it but i want to learn the underlying algorithm of this in Android. Please help, Thanks !
On Android you can execute your code before actually showing a push notification. They could simply send a push notification to all devices with an identifier, then the app can make a request to the server and get the needed information in order to show the push notification.
They can also send one push notification per device, as they can associate the push notification key with the user login, and the server would fire a push notification every time there is an event that demands a push notification.
But there are also other ways of doing this, for example, they can, for example run locally in background and create a local notification when the app decides it is necessary.
I'm using my application GCM push notification. I can send a message to the user via php. But I want to make a push notification can operate on its own. So in practice the day if not used, the application was not used today because you get a push message. If you send me the following hours or user himself he put option is sending messages to alert the user that hour. How do I do this?
Edited:
is can be local notification ? maybe i wrote wrong ? :)
i added this project in my app.but i need more :)
I would get the application to store the last used time somewhere, such as a database table.
Then create a PendingIntent and BroadcastReceiver to fire at the desired time. The broadcast receiver checks the last used time, and creates a standard Notification if the app was not used for that day.
