When you target Android O, you must implement one or more 105notification channels to display notifications to your users. 106 107You can create a notification channel for each distinct type of notification you need 108to send. You can also create notification channels to reflect choices made by users of 109your app. For example, you might setup separate notification channels for each 110conversation group created by a user in a messaging app. 111 112To create a channel, call `[NotificationManager.createNotificationChannels()][1]`. You 113can then use `[Notification.Builder.setChannel()][2]` to assign your notification to that 114channel. 115 116Users can now manage most of the settings associated with notifications using a 117consistent system UI. All notifications posted to a notification channel behave the 118same. To access the settings screen, use the `ACTION_CHANNEL_NOTIFICATION_SETTINGS` 119intent: 120 121``` 122Intent intent = new Intent(Settings.ACTION_CHANNEL_NOTIFICATION_SETTINGS); 123intent.putExtra(Settings.EXTRA_CHANNEL_ID, mChannel.getId()); 124intent.putExtra(Settings.EXTRA_APP_PACKAGE, getPackageName()); 125startActivity(intent); 126``` 127 128 129[1]: https://developer.android.com/reference/android/app/NotificationManager.html#createNotificationChannels(java.util.List<android.app.NotificationChannel>) 130[2]: https://android-dot-devsite.googleplex.com/reference/android/app/Notification.Builder.html#setChannel(java.lang.String) 131 ]]> 132 </intro> 133 </metadata> 134</sample> 135
