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

Question

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?

Answer 1

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 Other answers seem outdated.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.

I want to trigger heads-up notification but setting priority to PRIORITY_HIGH isn't working for me. – Thalassography

Apps can still take over the top position – Algorithm

priority max is deprecated. – Mazuma

PRIORITY_MAX is deprecated, use NotificationManager.IMPORTANCE_HIGH instead. – Mansfield

Answer 2

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

Answer 4

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);
