Code samples

The following code samples show you how to use the Push Service APIs of the BlackBerry 10 Native SDK to do the following:

• Create a PushService object to create a push session and perform push-related operations.
• Check the PushService object connection to the PNS agent running on the device. The PNS agent is a software component that maintains a connection with the PPG, and forwards push notifications that it receives from the PPG to the appropriate application instance.
• Create a push session to establish communication with the PNS agent.
• Start running the application in the background if it isn't already running when a push message arrives.
• Create a push channel to the PPG and subscribe with the Push Initiator. The Push Initiator uses the push channel to send push notifications to our sample application.
• Receive a push message.
• Acknowledge the receipt of a push message.
• Exit the application after processing a push message.
• Handle notifications in the BlackBerry Hub.
• Destroy a push channel and unsubscribe from the Push Initiator.
• Automatically detect a changed SIM card and stop receiving push messages on the device.
• Handle a push transport error and a PPG server error.
