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

Added in API level 1

public PendingIntent deleteIntent

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

Added in API level 19

public Bundle extras

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 NotificationListenerService implementations to extract detailed information from notification objects.

flags

Added in API level 1

public int flags

fullScreenIntent

Added in API level 9

public PendingIntent fullScreenIntent

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.

See also:

Notification.Builder.setFullScreenIntent(PendingIntent, boolean)

headsUpContentView

Added in API level 21
Deprecated in API level 24

public RemoteViews headsUpContentView

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

Added in API level 1
Deprecated in API level 23

public int icon

This field was deprecated in API level 23.
Use Builder.setSmallIcon(Icon) instead.

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

iconLevel

Added in API level 1

public int iconLevel

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.

FLAG_SHOW_LIGHTS
flags

ledOffMS

Added in API level 1
Deprecated in API level 26

public int ledOffMS

This field was deprecated in API level 26.
use NotificationChannel.shouldShowLights().

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

See also:

FLAG_SHOW_LIGHTS
flags

ledOnMS

Added in API level 1
Deprecated in API level 26

See also:

FLAG_SHOW_LIGHTS
flags

number

Added in API level 1

public int number

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 Build.VERSION_CODES.O, the number may be displayed as a badge icon in Launchers that support badging.

priority

Added in API level 16
Deprecated in API level 26

public int priority

This field was deprecated in API level 26.
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.

Value is PRIORITY_DEFAULT, PRIORITY_LOW, PRIORITY_MIN, PRIORITY_HIGH, or PRIORITY_MAX

publicVersion

Added in API level 21

public Notification publicVersion

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

Added in API level 1
Deprecated in API level 26

public Uri sound

This field was deprecated in API level 26.
use NotificationChannel.getSound().

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

Added in API level 1

public CharSequence tickerText

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).

See also:

tickerView

tickerView

Added in API level 11
Deprecated in API level 21

No longer displayed in the status bar as of API 21.

vibrate

Added in API level 1
Deprecated in API level 26

public long[] vibrate

This field was deprecated in API level 26.
use NotificationChannel.getVibrationPattern().

The pattern with which to vibrate.

To vibrate the default pattern, see defaults.

See also:

Vibrator.vibrate(long[], int)

visibility

Added in API level 21

public int visibility

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\u2014for example, to redact some portions\u2014see 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 VISIBILITY_PUBLIC, VISIBILITY_PRIVATE, or VISIBILITY_SECRET

when

Added in API level 1

public long when

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.

For apps targeting Build.VERSION_CODES.N and above, this time is not shown anymore by default and must be opted into by using Notification.Builder.setShowWhen(boolean)

Public constructors

Notification

Added in API level 1

public Notification ()

Constructs a Notification object with default values. You should use Builder instead.

Notification

Added in API level 1

public Notification (Parcel parcel)

Unflatten the notification from a parcel.

Parameters
`parcel`	`Parcel`

Notification

Added in API level 1

public Notification (int icon, 
                CharSequence tickerText, 
                long when)

This constructor is deprecated.
Use Builder instead.

Constructs a Notification object with the information needed to have a status bar icon without the standard expanded view.

Parameters
`icon`	`int`: the resource id of the icon to put in the status bar
`tickerText`	`CharSequence`: the text that flows by in the status bar when the notification first activates
`when`	`long`: the time to show in the time field, in the `System.currentTimeMillis` timebase

Public methods

clone

Added in API level 1

public Notification clone ()

Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression:

 x.clone() != x

will be true, and that the expression:

 x.clone().getClass() == x.getClass()

will be true, but these are not absolute requirements. While it is typically the case that:

 x.clone().equals(x)

will be true, this is not an absolute requirement.

By convention, the returned object should be obtained by calling super.clone. If a class and all of its superclasses (except Object) obey this convention, it will be the case that x.clone().getClass() == x.getClass().

By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified.

Returns
`Notification`	a clone of this instance.

describeContents

Added in API level 1

public int describeContents ()
