NotificationManager

open class NotificationManager
kotlin.Any
   ↳ android.app.NotificationManager

Class to notify the user of events that happen. This is how you tell the user that something has happened in the background.

Notifications can take different forms:

  • A persistent icon that goes in the status bar and is accessible through the launcher, (when the user selects it, a designated Intent can be launched),
  • Turning on or flashing LEDs on the device, or
  • Alerting the user by flashing the backlight, playing a sound, or vibrating.

Each of the notify methods takes an int id parameter and optionally a String tag parameter, which may be null. These parameters are used to form a pair (tag, id), or (null, id) if tag is unspecified. This pair identifies this notification from your app to the system, so that pair should be unique within your app. If you call one of the notify methods with a (tag, id) pair that is currently active and a new set of notification parameters, it will be updated. For example, if you pass a new status bar icon, the old icon in the status bar will be replaced with the new one. This is also the same tag and id you pass to the cancel(int) or cancel(java.lang.String,int) method to clear this notification.

For example, if a user has a channel named 'Messages' and the user changes their locale, this channel's name should be updated with the translation of 'Messages' in the new locale.

The importance of an existing channel will only be changed if the new importance is lower than the current value and the user has not altered any settings on this channel.

The group an existing channel will only be changed if the channel does not already belong to a group. All other fields are ignored for channels that already exist.

Checks whether the user has approved a given android.service.notification.NotificationListenerService.

The listener service must belong to the calling app.

Apps can request notification listener access by sending the user to the activity that matches the system intent action android.provider.Settings#ACTION_NOTIFICATION_LISTENER_SETTINGS.

Added in API level 23
open fun isNotificationPolicyAccessGranted(): Boolean

Checks the ability to modify notification do not disturb policy for the calling package.

Returns true if the calling package can modify notification policy.

matchesCallFilter

Added in API level 33
open fun matchesCallFilter(uri: Uri): Boolean

Returns whether a call from the provided URI is permitted to notify the user.

A true return value indicates one of the following: Do Not Disturb is not currently active; or the caller is a repeat caller and the current policy allows interruptions from repeat callers; or the caller is in the user's set of contacts whose calls are allowed to interrupt Do Not Disturb.

If Do Not Disturb is enabled and either no interruptions or only alarms are allowed, this method will return false regardless of input.

The provided URI should be a tel: or mailto: schema URI indicating the source of the call. For an accurate answer regarding whether the caller matches the user's permitted contacts, the path part of the URI must match an entry the Contacts database in the appropriate column.

Passing in a android.provider.ContactsContract.Contacts#CONTENT_LOOKUP_URI is also permissible, but should only be used for priority contact interruptions and may not provide accurate results in the case of repeat callers.

See also Person.Builder#setUri and android.provider.ContactsContract.Contacts#CONTENT_LOOKUP_URI for more information.

Callers of this method must have notification listener access, permission to read contacts, or have system permissions.

NOTE: This method calls into Contacts, which may take some time, and should not be called on the main thread.


This method may take several seconds to complete, so it should only be called from a worker thread.
Parameters
uri Uri: A URI representing a caller. Must not be null.
Return
Boolean A boolean indicating whether a call from the URI provided would be allowed to interrupt the user given the current filter.
