I want to write a program in which user can have something like chat in it. Actually we have a forum in which user can ask questian and if someone answers this question we want to send notification for questioner! Http Request seems good but I think this is not good if we have many users(50K for example) and every 30 sec we send http request to server from online users. I don't want the project to take a long time so I don't want to implement and write socket between android app and server myself. I find GCM but it only works when user have logged in Google account as far as I know. I also saw 'Parse.com' but I don't know if we can use this push notification service as push notification in Parse.com ; As far as I know Parse.com is manual and this is not feasible.

You can use Service and you can run it in background after define intervals.
For help how to run service forever in background look at this link:Need code example on how to run an Android service forever in the background even when device sleeping, like Whatsapp?

  • I know! I think you don't understand my question because of my bad description! i want library or service like GCM. the main problem is with server! and I want write a MVP so i don't want spent too much time on it. – Siavash Abdoli Sep 09 '15 at 06:55
  • httprequest must write on background too. but this is not good if 5k device every 30 sec ask from server: "what's up?"!!! so i think we need socket and i know we must write it on background. do you know any open source server or client? – Siavash Abdoli Sep 09 '15 at 07:00

For android Device some good options are GCM, Amazon SNS , Urban Airship.

Till yet Parse was the best option for me but they are discontinuing their service in 2017, so its not a good option.
