Push Notification in Blackberry
The BlackBerry Push Service is an essential component of the real-time,
always-on experience of BlackBerry smartphones. It offers an
efficient and reliable way of sending information to your users. It also
lets your application process information in the background
and notify users when their attention is required.
Refer this - developer.blackberry.com
First register for push Credentials. (See the above link).
Use Alternate Entry Point Application. The Background app will listen for the push notifications. The UI Application is used to register the device for getting the push notification. You need to activate the BIS(Blackberry Internet Service) on your device.
Client app will be given upon requests (rincethomas33@gmail.com)
