Android Notifications Setting Different priorities in notification


Example

 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);

When notification contains image and you want to auto expand image when notification received use "PRIORITY_MAX", you can use other priority levels as per requirments

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.
