NotificationManager

public class NotificationManager
extends Object

java.lang.Object
   ↳ 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.

The name and description should only be changed if the locale changes or in response to the user renaming this channel. 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.
