As stated by Deadshot, please use the Question Tags to state the name and full version number of the story format you are using, as answers can vary based on that information.
Push notification technologies (like the ones mentioned here) require a number of things to work:
1. That you have a access to a server running the relavent services needed to send the messages.
2. That you have implemented the required functionallity on the client-end to recieve and handle the messages being sent, in your example that would require adding code to the APK wrapper application. (or possibly to the story HTML file itself)
3. That you have implemented functionallity within your story project that knows what to do with the messages recieved by the APK wrapper application.
None of the above are trivial things to do.
Do you have access to the server mentioned in point 1?
Do you have access to a programmer (either yourself or another person) to implement the required code?
