A large-format version of contentView, giving the Notification an opportunity to show more detail. The system UI may choose to show this instead of the normal content view at its discretion. As of N, this field may be null. The expanded notification view is determined by the inputs to Notification.Builder; a custom RemoteViews can optionally be supplied with Notification.Builder.setCustomBigContentView(RemoteViews).

category

var category: String!

One of the predefined notification categories (see the CATEGORY_* constants) that best describes this Notification. May be used by the system for ranking and filtering.

color

var color: Int

Accent color (an ARGB integer like the constants in android.graphics.Color) to be applied by the standard Style templates when presenting this notification. The current template design constructs a colorful header image by overlaying the icon image (stenciled in white) atop a field of this color. Alpha components are ignored.

contentIntent

var contentIntent: PendingIntent!

The intent to execute when the expanded status entry is clicked. If this is an activity, it must include the android.content.Intent#FLAG_ACTIVITY_NEW_TASK flag, which requires that you take care of task management as described in the Tasks and Back Stack document. In particular, make sure to read the Start an Activity from a Notification page for the correct ways to launch an application from a notification.

contentView

var contentView: RemoteViews!

Deprecated: Deprecated in Java.

The view that will represent this notification in the notification list (which is pulled down from the status bar). As of N, this field may be null. The notification view is determined by the inputs to Notification.Builder; a custom RemoteViews can optionally be supplied with Notification.Builder.setCustomContentView(RemoteViews).

defaults

var defaults: Int

Deprecated: use NotificationChannel.getSound() and NotificationChannel.shouldShowLights() and NotificationChannel.shouldVibrate().

Specifies which values should be taken from the defaults.

To set, OR the desired from DEFAULT_SOUND, DEFAULT_VIBRATE, DEFAULT_LIGHTS. For all default values, use DEFAULT_ALL.

deleteIntent

var deleteIntent: PendingIntent!

The intent to execute when the notification is explicitly dismissed by the user, either with the "Clear All" button or by swiping it away individually. This probably shouldn't be launching an activity since several of those will be sent at the same time.

extras

var extras: Bundle!

Additional semantic data to be carried around with this Notification.

The extras keys defined here are intended to capture the original inputs to Builder APIs, and are intended to be used by android.service.notification.NotificationListenerService implementations to extract detailed information from notification objects.

flags

var flags: Int

fullScreenIntent

var fullScreenIntent: PendingIntent!

An intent to launch instead of posting the notification to the status bar.

The system UI may choose to display a heads-up notification, instead of launching this intent, while the user is using the device.

headsUpContentView

var headsUpContentView: RemoteViews!

Deprecated: Deprecated in Java.

A medium-format version of contentView, providing the Notification an opportunity to add action buttons to contentView. At its discretion, the system UI may choose to show this as a heads-up notification, which will pop up so the user can see it without leaving their current activity. As of N, this field may be null. The heads-up notification view is determined by the inputs to Notification.Builder; a custom RemoteViews can optionally be supplied with Notification.Builder.setCustomHeadsUpContentView(RemoteViews).

icon

var icon: Int

Deprecated: Use Builder.setSmallIcon(Icon) instead.

The resource id of a drawable to use as the icon in the status bar.

iconLevel

var iconLevel: Int

If the icon in the status bar is to have more than one level, you can set this. Otherwise, leave it at its default value of 0.

largeIcon

var largeIcon: Bitmap!

Deprecated: Use Builder.setLargeIcon(Icon) instead.

A large bitmap to be shown in the notification content area.

ledARGB

var ledARGB: Int

Deprecated: use NotificationChannel.shouldShowLights().

The color of the led. The hardware will do its best approximation.

ledOffMS

var ledOffMS: Int

Deprecated: use NotificationChannel.shouldShowLights().

The number of milliseconds for the LED to be off while it's flashing. The hardware will do its best approximation.

ledOnMS

var ledOnMS: Int

Deprecated: use NotificationChannel.shouldShowLights().

The number of milliseconds for the LED to be on while it's flashing. The hardware will do its best approximation.

number

var number: Int

The number of events that this notification represents. For example, in a new mail notification, this could be the number of unread messages. The system may or may not use this field to modify the appearance of the notification. Starting with android.os.Build.VERSION_CODES#O, the number may be displayed as a badge icon in Launchers that support badging.

priority

var priority: Int

Deprecated: use NotificationChannel.getImportance() instead.

Relative priority for this notification. Priority is an indication of how much of the user's valuable attention should be consumed by this notification. Low-priority notifications may be hidden from the user in certain situations, while the user might be interrupted for a higher-priority notification. The system will make a determination about how to interpret this priority when presenting the notification.

A notification that is at least PRIORITY_HIGH is more likely to be presented as a heads-up notification.

publicVersion

var publicVersion: Notification!

Replacement version of this notification whose content will be shown in an insecure context such as atop a secure keyguard. See visibility and VISIBILITY_PUBLIC.

sound

var sound: Uri!

Deprecated: use NotificationChannel.getSound().

The sound to play.

A notification that is noisy is more likely to be presented as a heads-up notification.

To play the default notification sound, see defaults.

tickerText

var tickerText: CharSequence!

Text that summarizes this notification for accessibility services. As of the L release, this text is no longer shown on screen, but it is still useful to accessibility services (where it serves as an audible announcement of the notification's appearance).

tickerView

var tickerView: RemoteViews!

Deprecated: Deprecated in Java.

Formerly, a view showing the tickerText. No longer displayed in the status bar as of API 21.

vibrate

var vibrate: LongArray!

Deprecated: use NotificationChannel.getVibrationPattern().

The pattern with which to vibrate.

To vibrate the default pattern, see defaults.

visibility

var visibility: Int

Sphere of visibility of this notification, which affects how and when the SystemUI reveals the notification's presence and contents in untrusted situations (namely, on the secure lockscreen and during screen sharing). The default level, VISIBILITY_PRIVATE, behaves exactly as notifications have always done on Android: The notification's icon and tickerText (if available) are shown in all situations, but the contents are only available if the device is unlocked for the appropriate user and there is no active screen sharing session. A more permissive policy can be expressed by VISIBILITY_PUBLIC; such a notification can be read even in an "insecure" context (that is, above a secure lockscreen or while screen sharing with a remote viewer). To modify the public version of this notification—for example, to redact some portions—see Builder.setPublicVersion(Notification). Finally, a notification can be made VISIBILITY_SECRET, which will suppress its icon and ticker until the user has bypassed the lockscreen.
Value is android.app.Notification#VISIBILITY_PUBLIC, android.app.Notification#VISIBILITY_PRIVATE, or android.app.Notification#VISIBILITY_SECRET

when

var when: Long

A timestamp related to this notification, in milliseconds since the epoch. Default value: Now. Choose a timestamp that will be most relevant to the user. For most finite events, this corresponds to the time the event happened (or will happen, in the case of events that have yet to occur but about which the user is being informed). Indefinite events should be timestamped according to when the activity began. Some examples:

• Notification of a new chat message should be stamped when the message was received.
• Notification of an ongoing file download (with a progress bar, for example) should be stamped when the download started.
• Notification of a completed file download should be stamped when the download finished.
• Notification of an upcoming meeting should be stamped with the time the meeting will begin (that is, in the future).
• Notification of an ongoing stopwatch (increasing timer) should be stamped with the watch's start time.
• Notification of an ongoing countdown timer should be stamped with the timer's end time.
