Delacy in GCM Message Recieving

[Pratibha Verma]

Hi all,

I am creating Chrome Extension. I am facing problem in GCM Message recieving. If i am online than message deliver instantly. But as soon as i went offline and opens my chrome again. I do not get message instantly. SomeTimes It takes even  more than an hour to recieve message. When i use

{ "name": "GCM Notifications", "description": "Chrome platform app.", "manifest_version": 2, "version": "0.1", "app": { "background": { "scripts": ["background.js"] } }, "permissions": ["gcm", "storage", "notifications"], "icons": { "128": "gcm_128.png" } }

 it works  perfect But as soon as i write it like 

{
	"name": "GCM Notifications",
	"description": "Chrome platform app.",
	"manifest_version": 2,
	"version": "0.1",
	"background": {
	"scripts": ["background.js"]
	},
	"permissions": ["gcm", "storage", "notifications"],
	"icons": { "128": "gcm_128.png" }
	}

it runs late.. Please tell me how to come out of this problem.

Hi, Pratibha,

When you are altering the manifest file like that you are switching from being app to extension. I think you should try to use additional key in the second manifest: "persistent": false, which would turn your background.js into an event page.

https://developer.chrome.com/apps/manifest  (chrome app manifest)

https://developer.chrome.com/extensions/manifest (chrome extensions manifest)

https://developer.chrome.com/extensions/event_pages (Extension event pages - explaining the persistent flag)

https://developer.chrome.com/extensions/background_pages (Explanation of what else you could do for extension's background page, like adding the "background" permission)

thanks.
