I'm trying to implement push notification with Aerogear unified push server and phonegap plugin(phonegap-plugin-push). 

One the application is installed and lauched , it registers with GCM and the devicetoken is registered with Aerogear UPS using the RESTful api.

I was able to send push notification from Aerogear admin console to the mobile application if any one criteria ( variant/alias/devicetype) is provided.

If none of the criteria is being set then the notifications are not being received. 

Any inputs on this would be really helpful.

Regards,

Nixad
