NotificationListenerService

public abstract class NotificationListenerService
extends Service

java.lang.Object
↳	android.content.Context
	↳	android.content.ContextWrapper
		↳	android.app.Service
			↳	android.service.notification.NotificationListenerService

A service that receives calls from the system when new notifications are posted or removed, or their ranking changed.

To extend this class, you must declare the service in your manifest file with the BIND_NOTIFICATION_LISTENER_SERVICE permission and include an intent filter with the SERVICE_INTERFACE action. For example:

 <service android:name=".NotificationListener"
          android:label="@string/service_name"
          android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
     <intent-filter>
         <action android:name="android.service.notification.NotificationListenerService" />
     </intent-filter>
 </service>

The service should wait for the onListenerConnected() event before performing any operations. The requestRebind(ComponentName) method is the only one that is safe to call before onListenerConnected() or after onListenerDisconnected().

Public methods

cancelAllNotifications

Added in API level 18

void cancelAllNotifications ()

Inform the notification manager about dismissal of all notifications.

Use this if your listener has a user interface that allows the user to dismiss all notifications, similar to the behavior of Android's status bar and notification panel. It should be called after the user invokes the "dismiss all" function of your UI; upon being informed, the notification manager will actually remove all active notifications and you will get multiple onNotificationRemoved(StatusBarNotification) callbacks.

The service should wait for the onListenerConnected() event before performing this operation.

See also:

cancelNotification(String, String, int)

cancelNotification

Added in API level 18

void cancelNotification (String pkg, 
                String tag, 
                int id)

This method was deprecated in API level 21.
Use cancelNotification(String) instead. Beginning with LOLLIPOP this method will no longer cancel the notification. It will continue to cancel the notification for applications whose targetSdkVersion is earlier than LOLLIPOP.

Inform the notification manager about dismissal of a single notification.

Use this if your listener has a user interface that allows the user to dismiss individual notifications, similar to the behavior of Android's status bar and notification panel. It should be called after the user dismisses a single notification using your UI; upon being informed, the notification manager will actually remove the notification and you will get an onNotificationRemoved(StatusBarNotification) callback.

Note: If your listener allows the user to fire a notification's contentIntent by tapping/clicking/etc., you should call this method at that time if the Notification in question has the FLAG_AUTO_CANCEL flag set.

The service should wait for the onListenerConnected() event before performing this operation.

Parameters
`pkg`	`String`: Package of the notifying app.
`tag`	`String`: Tag of the notification as specified by the notifying app in `notify(String, int, android.app.Notification)`.
`id`	`int`: ID of the notification as specified by the notifying app in `notify(String, int, android.app.Notification)`.

cancelNotification

Added in API level 21

void cancelNotification (String key)

Inform the notification manager about dismissal of a single notification.

The service should wait for the onListenerConnected() event before performing this operation.

Parameters
`key`	`String`: Notification to dismiss from `getKey()`.

cancelNotifications

Added in API level 21

void cancelNotifications (String[] keys)

Inform the notification manager about dismissal of specific notifications.

Use this if your listener has a user interface that allows the user to dismiss multiple notifications at once.

The service should wait for the onListenerConnected() event before performing this operation.

Parameters
`keys`	`String`: Notifications to dismiss, or `null` to dismiss all.

getActiveNotifications

Added in API level 21

StatusBarNotification[] getActiveNotifications (String[] keys)

Request one or more notifications by key. Useful if you have been keeping track of notifications but didn't want to retain the bits, and now need to go back and extract more data out of those notifications.

The service should wait for the onListenerConnected() event before performing this operation.

Parameters
`keys`	`String`: the keys of the notifications to request

Returns
`StatusBarNotification[]`	An array of notifications corresponding to the requested keys, in the same order as the key list.

getActiveNotifications

Added in API level 18

StatusBarNotification[] getActiveNotifications ()

Request the list of outstanding notifications (that is, those that are visible to the current user). Useful when you don't know what's already been posted.

The service should wait for the onListenerConnected() event before performing this operation.

Returns
`StatusBarNotification[]`	An array of active notifications, sorted in natural order.

getCurrentInterruptionFilter

Added in API level 21

int getCurrentInterruptionFilter ()

Gets the current notification interruption filter active on the host.

The interruption filter defines which notifications are allowed to interrupt the user (e.g. via sound & vibration) and is applied globally. Listeners can find out whether a specific notification matched the interruption filter via matchesInterruptionFilter().

The current filter may differ from the previously requested filter if the notification host does not support or refuses to apply the requested filter, or if another component changed the filter in the meantime.

Listen for updates using onInterruptionFilterChanged(int).

The service should wait for the onListenerConnected() event before performing this operation.

Returns
`int`	One of the INTERRUPTION_FILTER_ constants, or INTERRUPTION_FILTER_UNKNOWN when unavailable.

getCurrentListenerHints

Added in API level 21

int getCurrentListenerHints ()

Gets the set of hints representing current state.

The current state may differ from the requested state if the hint represents state shared across all listeners or a feature the notification host does not support or refuses to grant.

The service should wait for the onListenerConnected() event before performing this operation.

Returns
`int`	Zero or more of the HINT_ constants.

getCurrentRanking

Added in API level 21

NotificationListenerService.RankingMap getCurrentRanking ()

Returns current ranking information.

The returned object represents the current ranking snapshot and only applies for currently active notifications.

Generally you should use the RankingMap that is passed with events such as onNotificationPosted(StatusBarNotification, RankingMap), onNotificationRemoved(StatusBarNotification, RankingMap), and so on. This method should only be used when needing access outside of such events, for example to retrieve the RankingMap right after initialization.

The service should wait for the onListenerConnected() event before performing this operation.

Returns
`NotificationListenerService.RankingMap`	A `NotificationListenerService.RankingMap` object providing access to ranking information

onBind

Added in API level 18

IBinder onBind (Intent intent)

This is not the lifecycle event you are looking for.

The service should wait for the onListenerConnected() event before performing any operations.

Parameters

Returns
`IBinder`	Return an IBinder through which clients can call on to the service.

onDestroy

Added in API level 18

void onDestroy ()

Called by the system to notify a Service that it is no longer used and is being removed. The service should clean up any resources it holds (threads, registered receivers, etc) at this point. Upon return, there will be no more calls in to this Service object and it is effectively dead. Do not call this method directly.

onInterruptionFilterChanged

Added in API level 21

void onInterruptionFilterChanged (int interruptionFilter)

Implement this method to be notified when the interruption filter changed.

Parameters
`interruptionFilter`	`int`: The current `interruption filter`.

onListenerConnected

void onListenerHintsChanged (int hints)

Implement this method to be notified when the Listener hints change.

Parameters
`hints`	`int`: The current `listener hints`.

onNotificationPosted

Added in API level 21

void onNotificationPosted (StatusBarNotification sbn, 
                NotificationListenerService.RankingMap rankingMap)

Implement this method to learn about new notifications as they are posted by apps.

Parameters
`sbn`	`StatusBarNotification`: A data structure encapsulating the original `Notification` object as well as its identifying information (tag and id) and source (package name).
`rankingMap`	`NotificationListenerService.RankingMap`: The current ranking map that can be used to retrieve ranking information for active notifications, including the newly posted one.

Parameters
`rankingMap`	`NotificationListenerService.RankingMap`: The current ranking map that can be used to retrieve ranking information for active notifications.

onNotificationRemoved

Added in API level 18

void onNotificationRemoved (StatusBarNotification sbn)

Implement this method to learn when notifications are removed.

This might occur because the user has dismissed the notification using system UI (or another notification listener) or because the app has withdrawn the notification.

NOTE: The StatusBarNotification object you receive will be "light"; that is, the result from getNotification() may be missing some heavyweight fields such as contentView and largeIcon. However, all other fields on StatusBarNotification, sufficient to match this call with a prior call to onNotificationPosted(StatusBarNotification), will be intact.

Parameters
`sbn`	`StatusBarNotification`: A data structure encapsulating at least the original information (tag and id) and source (package name) used to post the `Notification` that was just removed.
