To change the unread count we need to call setNumber and use the NotificationManager to show the notification and update the badge count.
https://developer.android.com/reference/android/app/Notification.Builder.html#setNumber(int)
How do we update the count without showing the notification, I know its possible as whatsapp does it without showing the messages after some messages have been read from the app?
You can set the importance of a notification to be lower. At IMPORTANCE_NONE, it won't show up in the notification shade.
Although if you do that, how would the user ever see the new unread count?

I am working on android application on which I need to show count on app icon when ever I receive value from api. I am able to update badge value on app icon through notification, but I am unable to update badge count on app icon without notification.
so my question is, do we always need a notification to update count on app icon?
I checked what's app and found that the count on app icon increased through notification but they have clearly mention on their site that Badge count is a notification functionality provided by your launcher and is not a function of WhatsApp. If you continue to experience issues, please contact your phone's manufacturer.
so again my question is how the count is getting decreased after reading the message, suppose the count is 59 and after reading one message count goes to 58?
Yes. We can do it.
By default, you can create a onGoing Notification builder and notify with priority is LOW, and at the same time, you display by ShortcutBadger.
Make sure the notification is silent mode.
I want to add the count of unread notification at my app icon
I tried this link but this was not helpful
Take a look this might work and can make your Android App showing the count of unread messages as a badge on your App shortcut

I am able to show total push notifications count on top bar but still looking for displaying each notification on top bar. Currently, it shows total count and last notification received. I want to show all notifications like total SMS count and each SMS displayed in Android. Immediate response will be highly appreciated. Thanks
You have to setup somehow a counter that will be your notification ID. If the id is different on each notification, you'll be able to show it all on the notification bar. More on Notifications here and here
I have a custom launcher, and I'm showing a custom notification icon
If user clicks on the notification icon he gets to see the notification. This part is working as expected. I can expand the notification list.
But now my requirement is, since I'm using a custom Notification icon I wish to show the notification count(if there are any notification, or if there are 10 notifications). I wish to show the number of unread/unchecked notification user has.
How to get the number(count) of unchecked notification?
I have gone through couple of examples and link like:
Link 1
Link 2
But all these links show how to create notifications, or how to expand notification list. How to get the notification count?
Any piece of code or example is highly appreciable.
Thanks
I would like to share my strategy on how to get the notification count. As I read the documentation, I have not seen any way to store and retrieve the notification count. I am doing a Note Reminder and this reminder alarms at a particular date. Given I have many reminders, sending notification to each of them simply replaces the one on the notification list. This is not nice. Neither my receiver has any way to know the nth time the notification was called. The notification is lack-luster in this case in my opinion.
So, one strategy I saw is to defer the counting responsibility directly to the database. I have to provide a method which returns the number of lapsed reminders I have on the database, tuck it in as an extra on the intent inside the pending intent which launch my receiver. From there I can unpack the extras and set the notification accordingly. This way, I got the information I need and I can model the notification content as such showing the number of reminders that are left untouched. Adding a count badge right next to the icon does not seem possible given the default android but is possible using third-party solutions or using well known android UI like TouchWiz in Samsung, or the one in Xperia. Searching the web, it seems making it so is another different story. I preferred not to do it and simply show through the content I have n count of lapsed reminders.
I hope this help people who are having similar problem regarding retrieving or storing notification count given a unique-per-application notification id.
Hope this helps!
you can use this exemple it work for me
Notification notification = new Notification(R.drawable.direction, "Cool Notification",
System.currentTimeMillis());
/********LIKE THIS*********/
notification.number = notificationCount++;
/********LIKE THIS*********/
notification.setLatestEventInfo(context, "Cool Notification Title",
"updated notificaiton message", null);
NotificationManager nm = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);
nm.notify(R.id.my_motification, notification);
So you can increment the notification.number every time you display a notification.
If you're targeting API level 18+, then you're in luck, as you can provide a NotificationListenerService to access the current notifications and/or be alerted whenever they are created or dismissed.
Otherwise, you can use the old trick of registering an AccessbilityService and listening on AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED events. This is a good example of this approach.
In my app I am applying push notifications and making them using the notificationCompat class.
I am assigning each notification a unique ID therefore, each one is visible seperately in the notification bar.
When the user clicks on a notification, using a pending intent, I am directing the user towards a certain activity, where he can see all the previous notifications. ( I read them from mysql db ).
question 1 : I want all the notifications in the status bar get cleared if the user clicks only on one of them. Can be a any random one (given it is from my app). the setAutoCancel() method, only removes the one pressed, and I cant seem to know where I would implement the cancelAll() method.
Answer :
#Override
protected void onResume()
{
super.onResume();
NotificationManager notificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.cancelAll();
}
question 2 : Since each notification has unique ID, sending several notifications from an individual app, and in case of not checking from the user, might result in several icons to appear in the notification bar. Android, starts collecting them and showing badge numbers on them once they start taking too much space and the system realizes there is no enough space for them.
Is there any method to combine them all from the beginning ? That is, whenever I send a notification, and it is not checked, the second one should be added and a single icon should appear on the bar with the number 2 or + , whatever the system uses.
I'd like to combine question 1 and 2 into a single answer: Do not show multiple notifications! Show one notification and update it when you have more than one unchecked notification. As a user I would get really annoyed if my notification bar was spammed with notifications from a single app. Think of the GMail app and it's notifications if you would get one per incoming e-mail.
On pre 4.1 devices you'll have to make do with the Normal View. If you have only one unchecked message you could show the contents of the message immediately in the notification, and if you have more than one you could do something like the GMail notification and show something like "5 unchecked messages".
On 4.1+ devices you can use the Big View to show all of them at once.
