NotificationListenerService Example

NotificationListenerService-Example

##Introduction NotificationListenerService is introduced in Android 4.3 (API 18). It allows an application to receive information about notifications as it creates or removes. NotificationListenerService class is derived from the Service class. It has two abstract methods namely 1. onNotificationPosted 2. onNotificationRemoved.
To use NotificationListenerService, we need to create a java file which extends NotificationListenerService and implement two callback methods. Both methods have a parameter named "sbn", which is an object of StatusBarNotification class. StatusBarNotification provides necessary information about Notifications. NotificationListenerService provides facility to fetch active notifications using getActiveNotifications and also provides a feature to remove notifications using cancelAllNotifications.

##Useful Methods

1. NotificationListenerService
   • onNotificationPosted
   • onNotificationRemoved
2. StatusBarNotification
   • getId
   • getNotification
   • getPackageName
   • getPostTime
   • isClearable
   • isOngoing

##Note User require to enable notification permission from "Settings > Security > Notification access".

Hi, I cannot seems to get it work in marshmallow (Don't have any other version of android) and in emulator is not working as well (7.0)

How to know if user clicked on the notification (opening the related app) or simply deleted it

Hi, I'm working with notifications generated by every app (not only mine) on my Android device (android 5.1.1). By extending NotificationListenerService I'm able to know when a push notification is posted (overriding the "onNotificationPosted" method) and when a notification is removed (overriding the "onNotificationRemoved" method).

The problem is that I would like to know how the notification was removed: a) by clicking it (so opening the app) or b) by swyping it (so it is only removed) ?

Is it possible to know it? Thank you in advance!

Exclude file "local.properties" from version control

Please exclude the file "local.properties" from version control, it prevents the project from building on systems with a different sdk path. By removing this file manually after cloning the repository, I was able to build the project just fine in Android Studio.

Btw, thanks for the example code, it was just what I was looking for!

Typo

public void onNotificationRemoved(StatusBarNotification sbn) {
Log.i(TAG,"********** onNOtificationRemoved");
seems like the "O" is uppercase by mistake

Service stopped on user swicthed

I have two users on a tablet and created a class extending NotificationListenerService, which listens to notioficatiuons. Now when I switch user this service is getting killed. Is it the expected behaviour ? As i want to catch those notifications as well when I am not in this user. Please help..

Question: is it possible to hide heads-up notifications?

So that each notification that any app shows, will show only an icon instead of heads-up notification ?
I've asked about it here:
