I am trying implementing Push notifications for android mobile with the help of Google Cloud Messaging Service. As a backend, i am using Web API as a server which will connect with my SignalR to get the notifications from my web application. Here, i am able to get the instant notifications to Web API after connecting with SignalR. But, After i send the update to GCM to send notification, some times its sending instantly and most of the times notification is either not sending to mobile and very late while sending.
Please do suggest me on this to solve the issue ans to send messages from Web API to mobile instantly without any delay.
