    }

i am using this code to show the notification...but it shows only one notification content...but icon shows no of notification...

Answer 1

Remember that if you want show multiple notify for different objects, you have to assign a different Notification ID for each one.

For example, if you have 2 different objects, you have to call

mNotificationManager.notify(0, notifyDetails);

and

mNotificationManager.notify(1, notifyDetails);

If you don't do that, Notification will be always one and will be always updated.

Answer 2

Each icon corresponds to one notification; you cannot associate multiple notifications with one instance of an item on the notification bar.

You can, however, overlay a number on top of your icon (e.g. to show the number of events that icon represents) like some SMS and email applications do.

This is done with the number instance variable of Notification, as you have in your code snippet above.

Edit:
To be more clear: If you want multiple notifications, you need to create multiple Notification objects and call NotificationManager.notify() multiple times.

Each Notification can only produce one icon, can have one piece of content inside the notification area, and can have one Intent associated with it.
