Android 13: move my foreground notification back up?

I have an app which has a foreground task, and posts an ongoing notification.
Earlier until version 12, it was displayed at the topmost place on the notification drawer.
Android 13 changes this, making it appear down below:
As you can see, messenger is preceding my application.
Can I somehow post the ongoing notification to appear at the top?
I'm using it a lot so would be much more comfortable if I can have it on top (where now the messenger is).
Notification is created with basic builder:
Notification.Builder b;
Notification notification = b.setTicker(ticker)
.setSmallIcon(smallicon)
.setContentTitle(title)
.setContentText(text)
.setContentIntent(contentIntent)
.setWhen(0)
.setAutoCancel(false)
.setOngoing(true)
.build();
Can I somehow force it to the first place?

You can try to set priority height in your code. And also avoid setting messenger app superposition on other apps. I think it will help.

Android update app badge count without push notification Android Oreo+

I want to update app icon badge count without push notifications(eg. Silent push). I simply want to update app badge count after reading any notifications inside the app similar to linkedIn, where its updating the count on app badge when am reading any notification. Currently I've implemented the solution where I am having payload from FCM with badge count and updating it with android notification builder with silent push notification channel configured.
var notificationBuilder = NotificationCompat.Builder(this#MainActivity, CHANNEL_ID)
.setContentTitle("New Messages")
.setContentText("You've received 3 new messages.")
.setSmallIcon(R.drawable.ic_notify_status)
.setNumber(messageCount)
.build()
but that is not gonna work for me as I also need to update the count once I've read any notification inside the app. If I clear the notification from notification tray then count is also disappearing from app badge, is there any way that I can set that count without push notification within the app? Thanks in advance.

So after working around badge count update feature so long, I've come to conclusion that Android do not provide any api to update badge count on app icon without notification. In android we can internally send notification and with the help of this we can update badge count.
So we need to notify the device for updating badge count, without notifying we can't update it. If we are sending count to Notification Builder then we just need to take care to update badge count to keep the notification id same every time if we want to update the badge count otherwise it will add count to its previous notification. Just keep notification id same and create a separate channel with silent push to update badge count.
public static int NOTIFICATION_ID = 1001;
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(NOTIFICATION_ID, notificationBuilder.build());
that solution will override previous count.

Adding push notifications to a group when their count is more than one

Currently I have created group key for my android app so that the push notifications can be grouped together. My minimum target api level is 24 so I do not need to create any Summary Notification. What I am doing is something like this:
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context, channelID)
.setSmallIcon(R.drawable.applogo)
.setContentTitle(sourceName)
.setContentText(messageTitle)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setSound(defaultSoundUri)
.setAutoCancel(true)
.setContentIntent(contentIntent)
.setGroup(GROUPID)
Thus I am creating the NotificationCompat Builder. The problem what I am facing is Notifications are being grouped together after the 4th one. The first three notifications are being displayed separately in the notification tray. When the fourth one is coming, they are grouped together. What I want to know is that is this the default behavior and if so then how can I change it like notifications will be grouped together when the 2nd one comes?

Notifications will be grouped after 4, this is the default behaviour since 24. And to trigger group notification less than 4 you need to create group summary notification.

Foreground Service's Notification Only says "xxx is running ... Tap for more information..."

I wanted to implement a foreground service with an ongoing notification. So far I just want some proper title and some text, but even that doesn't work. Android only shows
"AppXXX is running
Tap for more information or stop app"
The code of making the notification is as followed:
Notification notification =
new Notification.Builder(this, CHANNEL_ID)
.setContentTitle("title")
.setTicker("ticker")
.setContentIntent(pendingIntent)
.build();

setSmallIcon(...) is required for the notification to show properly. According to the anatomy of an android notification here:
Small icon: This is required and set with setSmallIcon()

Android: How can I put my notification on top of notification area?

I'm trying to put my notification on top of notification area.
A solution is to set the parameter "when" to my notification object with a future time like:
notification.when = System.currentTimeMills()*2;
The code that I'm using in this:
long timeNotification = System.currentTimeMillis()*2;
Notification notification = new Notification(statusIcon,c.getResources().getString(R.string.app_name),timeNotification);
notification.flags = Notification.FLAG_ONGOING_EVENT | Notification.FLAG_NO_CLEAR;
notification.when = timeNotification;
notification.priority = Notification.PRIORITY_MAX;
but some apps (like Facebook) are able to put a simple notification with their current time over mine.
If I refresh my notification it remains under these ones.
What parameters I have to set to put my Notification to the top of the notifications area?

You should do this. Other answers seem outdated.
NotificationCompat.Builder mBuilder =
(NotificationCompat.Builder) new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.some_small_icon)
.setContentTitle("Title")
.setContentText("This is a test notification with MAX priority")
.setPriority(Notification.PRIORITY_MAX);
setPriority(Notification.PRIORITY_MAX) is important. It can also be replaced with any of the following as per requirement.
Different Priority Levels Info:
PRIORITY_MAX --
Use for critical and urgent notifications that alert the user to a condition that is time-critical or needs to be resolved before they can continue with a particular task.
PRIORITY_HIGH --
Use primarily for important communication, such as message or chat events with content that is particularly interesting for the user. High-priority notifications trigger the heads-up notification display.
PRIORITY_DEFAULT --
Use for all notifications that don't fall into any of the other priorities described here.
PRIORITY_LOW --
Use for notifications that you want the user to be informed about, but that are less urgent. Low-priority notifications tend to show up at the bottom of the list, which makes them a good choice for things like public or undirected social updates: The user has asked to be notified about them, but these notifications should never take precedence over urgent or direct communication.
PRIORITY_MIN --
Use for contextual or background information such as weather information or contextual location information. Minimum-priority notifications do not appear in the status bar. The user discovers them on expanding the notification shade.

You can make your notification Ongoing, when it will appear higher then other usual notification. But in this case user would not be able to clear it manually.
In order to do this set flags to your Notification object:
notif.flags = Notification.FLAG_ONGOING_EVENT | Notification.FLAG_NO_CLEAR

Try setting priority of the notification to high
documentation > Notification Priority
Also check this question may it could help you Pin Notification to top of notification area

Please note that if you want a "heads-up" notification i.e., one that displays over the top of the current user window you must have the following set in your builder:
setDefaults(NotificationCompat.DEFAULT_VIBRATE)
The reference is in the javadoc:
A notification that vibrates is more likely to be presented as a heads-up notification, on some platforms.
Complete example for a heads-up notification:
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.some_small_icon)
.setContentTitle("Title")
.setContentText("This is a test notification with MAX priority")
.setPriority(Notification.PRIORITY_MAX)
.setDefaults(NotificationCompat.DEFAULT_VIBRATE);
