Remarks

Helper class to add wearable extensions to notifications. <p class="note"> See Creating Notifications for Android Wear for more information on how to use this class.

To create a notification with wearable extensions: <ol> <li>Create a android.app.Notification.Builder, setting any desired properties. <li>Create a android.app.Notification.WearableExtender. <li>Set wearable-specific properties using the add and set methods of android.app.Notification.WearableExtender. <li>Call android.app.Notification.Builder#extend to apply the extensions to a notification. <li>Post the notification to the notification system with the NotificationManager.notify(...) methods. </ol>

Notification notif = new Notification.Builder(mContext)
                    .setContentTitle(&quot;New mail from &quot; + sender.toString())
                    .setContentText(subject)
                    .setSmallIcon(R.drawable.new_mail)
                    .extend(new Notification.WearableExtender()
                            .setContentIcon(R.drawable.new_mail))
                    .build();
            NotificationManager notificationManger =
                    (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
            notificationManger.notify(0, notif);

Wearable extensions can be accessed on an existing notification by using the WearableExtender(Notification) constructor, and then using the get methods to access values.

Notification.WearableExtender wearableExtender = new Notification.WearableExtender(
                    notification);
            List&lt;Notification&gt; pages = wearableExtender.getPages();

Constructors

Notification.WearableExtender()	Create a `android.app.Notification.WearableExtender` with default options.
Notification.WearableExtender(Notification)

Fields

ScreenTimeoutLong	Sentinel value for use with `#setHintScreenTimeout` to keep the screen on for a longer amount of time when this notification is displayed on the screen.
ScreenTimeoutShort	Sentinel value for use with `#setHintScreenTimeout` to keep the screen on for a short amount of time when this notification is displayed on the screen.
UnsetActionIndex	Sentinel value for an action index that is unset.

Properties

Actions	Get the wearable actions present on this notification.
Background	Get a background image to be displayed behind the notification content.
BridgeTag	Returns the bridge tag of the notification.
Class	Returns the runtime class of this `Object`. (Inherited from Object)
ContentAction	Get the index of the notification action, if any, that was specified as the primary action.
ContentIcon	Get an icon that goes with the content of this notification.
ContentIconGravity	Get the gravity that the content icon should have within the notification display.
ContentIntentAvailableOffline	Get whether the content intent is available when the wearable device is not connected to a companion device.
CustomContentHeight	Get the custom height in pixels for the display of this notification's content.
CustomSizePreset	Get the custom size preset for the display of this notification out of the available presets found in `android.app.Notification.WearableExtender`, e.
DismissalId	Returns the dismissal id of the notification.
DisplayIntent	Get the intent to launch inside of an activity view when displaying this notification.
Gravity	Get the gravity that this notification should have within the available viewport space.
Handle	The handle to the underlying Android instance. (Inherited from Object)
HintAmbientBigPicture	Get a hint that this notification's `BigPictureStyle` (if present) should be converted to low-bit and displayed in ambient mode, especially useful for barcodes and qr codes, as well as other simple black-and-white tickets.
HintAvoidBackgroundClipping	Get a hint that this notification's background should not be clipped if possible, and should instead be resized to fully display on the screen, retaining the aspect ratio of the image.
HintContentIntentLaunchesActivity	Get a hint that this notification's content intent will launch an `Activity` directly, telling the platform that it can generate the appropriate transitions
HintHideIcon	Get a hint that this notification's icon should not be displayed.
HintScreenTimeout	Get the duration, in milliseconds, that the screen should remain on for when this notification is displayed.
HintShowBackgroundOnly	Get a visual hint that only the background image of this notification should be displayed, and other semantic content should be hidden.
JniIdentityHashCode	(Inherited from Object)
JniPeerMembers
Pages	Get the array of additional pages of content for displaying this notification.
PeerReference	(Inherited from Object)
StartScrollBottom	Get whether the scrolling position for the contents of this notification should start at the bottom of the contents instead of the top when the contents are too long to display within the screen.
ThresholdClass	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code. (Inherited from Object)
ThresholdType	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code. (Inherited from Object)
