Is it possible send push notifications from a JEE application to Android app instead of from QuickBlox admin panel? We are using Spring Framework on our application. So I need some suggestion WRT spring only.
Yes, you can able to send the push notification to your mobile users by using QuickBlox Rest API. Its a restfull solution provided by QuickBlox guys which you just consumes the services and use accordingly. And you mentioned that your application is using spring framework so its quite easy to consume the resources through Spring RestFull and use. Please refer to the following official link given by QuickBlox team about push notification and all.
