How to change Android Notification using Accessibility API -

i able intercept notifications using accessablity service. block events seen :

   @override public void onaccessibilityevent(accessibilityevent event) {     log.d(tag, "inside onaccessibilityevent");     if (event.geteventtype() ==           accessibilityevent.type_notification_state_changed){         sqldb db = new sqldb(this);         notificationobject no = new notificationobject();         no.setnoficationpackage(string.valueof(event.getpackagename()));         no.setnotificationtext(string.valueof(event.gettext().tostring()));         no.setnotificationdtm(new date());         db.addnotification(no);         log.d(tag, "saved event");     } } 

what want change notification not considered missed call event. possible on os 4.0+?

thanks.

another application's notification read-only. so, code "notification.a = b; "cause permission problem.

public void onaccessibilityevent(accessibilityevent event) {         // todo auto-generated method stub         if (event.geteventtype() == accessibilityevent.type_notification_state_changed) {             //do something, eg getting packagename             final string packagename = string.valueof(event.getpackagename());             final string text = string.valueof(event.gettext());              if(target_package.equals(packagename)){                 notification n = (notification) event.getparcelabledata();         } }
