1. Run the attached app

3. Click createChannel and wait for the callback response
4. Send a push notification to the app from this page: http://pushsdk16-vmyyz.labyyz.testnet.rim.net/sample-push-initiator/Push
After the "invoked" notification is displayed in the app, the app cannot be minimized or closed by swiping.
Closing the app using blackberry.app.exit() works.
