I don't understand how to use AlarmManager to post notifications. I think that all notifications is managered by NotificationManager but not AlarmManager, although they are started and canceled according with alarms life cycle.In fact, The behavior of notifications were right, no the problem, before I changed some thing in my code. If need, I can write these difference code snippet to here.

Are you using AlarmManager to post these notifications? Is so, have you set a repeating alarm? Is so, are you canceling your alarm registered with AlarmManager when the notification is canceled?On Sun, Feb 6, 2011 at 7:21 AM, San Zhang <dahua007.zs@gmail.com> wrote:
The results are same: The notification can be deleted from status bar, but it would be displayed twice (and only twice) when another alarm notification (with different value of noti_id) be displayed. I don't understand what is happened. I have searched internet by google but not answer for this.
