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 Other answers seem outdated.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.
