Push notifications

I have been unable to make push notifications work for my android device. What am I missing? I have followed all of the steps on this video https://www.youtube.com/watch?v=bN0Xpu0AmW0
a few times with no luck. I send the notification out but nothing shows up on my phone.

I am testing it on a galaxy s5 and the app is not in the app store yet but rather on the phonegap build site. Is this an issue?
