NotificationListenerService

Kotlin |Java

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 Manifest.permission.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:exported="false"
          android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
     <intent-filter>
         <action android:name="android.service.notification.NotificationListenerService" />
     </intent-filter>
     <meta-data
               android:name="android.service.notification.default_filter_types"
               android:value="conversations|alerting">
           </meta-data>
     <meta-data
               android:name="android.service.notification.disabled_filter_types"
               android:value="ongoing|silent">
           </meta-data>
 </service>

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

Notification listeners cannot get notification access or be bound by the system on low-RAM devices running Android Q (and below). The system also ignores notification listeners running in a work profile. A DevicePolicyManager might block notifications originating from a work profile.

From Build.VERSION_CODES#N onward all callbacks are called on the main thread. Prior to N, there is no guarantee on what thread the callback will happen.

Inherited constants

From class android.app.Service

`int`	`START_CONTINUATION_MASK` Bits returned by `onStartCommand(Intent, int, int)` describing how to continue the service if it is killed.
`int`	`START_FLAG_REDELIVERY` This flag is set in `onStartCommand(Intent, int, int)` if the Intent is a re-delivery of a previously delivered intent, because the service had previously returned `START_REDELIVER_INTENT` but had been killed before calling `stopSelf(int)` for that Intent.
`int`	`START_FLAG_RETRY` This flag is set in `onStartCommand(Intent, int, int)` if the Intent is a retry because the original attempt never got to or returned from `onStartCommand(android.content.Intent, int, int)`.
`int`	`START_NOT_STICKY` Constant to return from `onStartCommand(Intent, int, int)`: if this service's process is killed while it is started (after returning from `onStartCommand(Intent, int, int)`), and there are no new start intents to deliver to it, then take the service out of the started state and don't recreate until a future explicit call to `Context.startService(Intent)`.
`int`	`START_REDELIVER_INTENT` Constant to return from `onStartCommand(Intent, int, int)`: if this service's process is killed while it is started (after returning from `onStartCommand(Intent, int, int)`), then it will be scheduled for a restart and the last delivered Intent re-delivered to it again via `onStartCommand(Intent, int, int)`.
`int`	`START_STICKY` Constant to return from `onStartCommand(Intent, int, int)`: if this service's process is killed while it is started (after returning from `onStartCommand(Intent, int, int)`), then leave it in the started state but don't retain this delivered intent.
`int`	`START_STICKY_COMPATIBILITY` Constant to return from `onStartCommand(Intent, int, int)`: compatibility version of `START_STICKY` that does not guarantee that `onStartCommand(Intent, int, int)` will be called again after being killed.
`int`	`STOP_FOREGROUND_DETACH` Selector for `stopForeground(int)`: if set, the notification previously supplied to `startForeground(int, Notification)` will be detached from the service's lifecycle.
`int`	`STOP_FOREGROUND_LEGACY` This constant was deprecated in API level 33. Use `STOP_FOREGROUND_DETACH` instead. The legacy behavior was inconsistent, leading to bugs around unpredictable results.
`int`	`STOP_FOREGROUND_REMOVE` Selector for `stopForeground(int)`: if supplied, the notification previously supplied to `startForeground(int, Notification)` will be cancelled and removed from display.

cancelAllNotifications

Added in API level 18

public final 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(android.service.notification.StatusBarNotification) callbacks.

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

cancelNotification(String, String, int)

cancelNotification

Added in API level 18
Deprecated in API level 21

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

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

Note: If your listener allows the user to fire a notification's Notification.contentIntent by tapping/clicking/etc., you should call this method at that time if the Notification in question has the Notification.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 `NotificationManager.notify(String, int, android.app.Notification)`.
`id`	`int`: ID of the notification as specified by the notifying app in `NotificationManager.notify(String, int, android.app.Notification)`.
