Hide notification from Foreground Service on click notification Action

I have an Alarm App that have foreground service with a Heads-Up Notification and that notification have two actions where one send an intent to the Service and can open an activity depending on the app configuration.
The problem is that when i click on a action that sends the intent to the service the notification doesn't hide. This not seems to occur when the intent opens a Activity
I don't want a foreground service without a Notification, i just want it to hide it back to the Notification Drawer when the intent is sent to the service
Here is the code:
NotificationCompat.Builder(mAlarmApplication, CHANNEL_ID)
.setSmallIcon(R.drawable.ic_notification_alarm)
.setAutoCancel(false)
.setOngoing(true)
.setVibrate(LongArray(0))
.setContentTitle("Title")
.setContentText("Content")
.addAction(0, dismissActionText, dismissPendingIntent)
.setCategory(NotificationCompat.CATEGORY_ALARM)
.setPriority(NotificationCompat.PRIORITY_MAX)
.setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
.setContentIntent(alarmScreenPendingIntent)
.setFullScreenIntent(alarmScreenPendingIntent, true)
Here is the link of the app https://play.google.com/store/apps/details?id=com.garageapp.alarmchallenges.
The problem occurs when alarm start and my current solution is to update the old heads up notification with a new one that is not a heads up but the UX is not a good because on Android 8+ the notification new notification pops up aging

Seems like your Notification is bonded with your Service. If so, then you have to kill the notification in Service
Did you try?
public static void cancelNotification(Context ctx, int notifyId) {
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager nMgr = (NotificationManager) ctx.getSystemService(ns);
nMgr.cancel(notifyId);
}

You are using .setOngoing(true) which should not be removed while service is working.
.setAutoCancel(true) will also not working with .setOngoing(true).
You have to use .setOngoing(false) to dismiss the notification.

If you or user remove your foreground notification your service will go to background, I think that best work is to not using heads up notification for foreground by not setting its priority to MAX
Use two notifications at same time one in drawer and another heads up:
-The first notification with priority DEFAULT for starting foreground ( auto cancel set to false and ongoing set to true) show this one with startForground()
-The Second notification (Heads up (Priority MAX) auto cancel set to true and on going set to false) for your actions show this with notifyManager.notify()
These two notifications must have different IDs
another solution:
If you want to use one heads up notification with actions for foreground service you may do this:
use a heads up notification with your action buttons for foreground service when the user clicks actions this action must call the foreground service and then the foreground service could call startForeground (with same id) with a new notification with priority set to default, if your notification could not be updated you may need to call stopForeground(true) or notificationManager.cancel(id) first before calling startForeground with new notification. both of these two notifications should has on going set to true and auto cancel set to false
In my opinion the first solution is better than the second because the notification may not update in second solution.

As the documentation says :
A started service can use the startForeground(int, Notification) API to put the service in a foreground state, where the system considers it to be something the user is actively aware of ...
android system does not allow you to have a foreground service without notification or a hidden notification. and that's because of user awareness of what is happening in his/her system.
also killing the notification will stop your foreground service.
so you never can have both of the options (foreground service and hidden notification)
a not clear solution for your problem:
when you call action that sends the intent to the service, do this with a mediator activity i mean first open an activity and in the activity send intent to the service.
I hope this solve your problem as you told :
The problem is that when i click on a action that sends the intent to the service the notification doesn't hide. This not seems to occur when the intent opens a Activity

Android update ticker text of Foreground Service

I have service that I've used startForeground() method with a Notification.
i'm saving an instance of my Notification in order to update it easily.
there was no problem updating any of the field in it, but when i'm updating the ticker text and notifying the NotifcationManager about the change - it doesn't show my new ticker.
Is it event possible to update the Notification's ticker text of a foreground Service's Notification ?
Is so - any idea why isn't it updating and showing the new ticker on screen ?

I found a solution that feels funny.
I can call Service.stopForeground(true);
followed by Service.startForeground(myNotificationId, myNotification) with the notification with the new ticker and it does the trick but it doesn't make sense..

Switching Android notification from FLAG_ONGOING_EVENT to cancelable

I have an ongoing task and after it finishes, I want the notification to become cancelable.
For that, I create a new notification with notification.flags as zero, but the notification keeps being un-cancelable.

Apparently, FLAG_FOREGROUND_SERVICE prevented the notification from turning into cancelable, even after reseting the flags.
After removing FLAG_FOREGROUND_SERVICE and using only 0 or FLAG_ONGOING_EVENT, the notification could be made cancelable or un-cancelable - respectively.

Please take a look here : Android update notification
In short what you will do is this:
Create your notification first time and assign a notification ID to it.
Once your service is done executing create a new cancelable notification with the same id
fire that notification, it should make the previous notification cancelable .

Android - jelly bean notification dismiss button

The google play music app has a little 'X' in the top right corner, instead of displaying the time and a miniature notification icon in that location. Tapping the button kills the player and closes the notification. Great!
I'd like to do the same with my app - Is this only possible by inflating remote views and associating a custom button with an intent to destroy the service, or is there some notification builder methods that I'm overlooking which do that job?

There are no notification builder methods which achieve this. The only solution is to create a custom button with a pending intent to perform the action required.

Status bar Notification in android

I want to set a onClickListner for a status bar Notification. How it is possible ? Please help. Now i can load a Activity by using the pending intent. I like to set a onClickListner for the notificatioin.

It is not possible to set an OnClickListener for a notification. Because of the way notifications are handled/displayed there is no way to guarantee that the process that created the notification will be running at the time the notification is clicked. This means that any code you wrote to provide click handling may not be running.
If you need click listener style behavior you will have to do it using the PendingIntent: set it to start a Service that runs the logic or to use an Intent that is received by a BroadcastReceiver. This will let you perform activity without requiring a UI.
