I am using LAMP stack in my server and I want to send data from the server to the android device. The android device should not make a request to the server for getting the data , the server will send the data on its own and the android device should receive it using a background service. What should I do?
P.S -> I know GCM and parse.com do this using push notifications but is there any other way?
In General I can see only three options,
I would like to recommend you GCM way. I haven't use Signal R in android native mobile applications but i have use it in web application development. I have added some links above, hope it will help you.
