Answer 1

Daniel - Dude there is an issue with the GCM documentation ! Use Browser key as the authorization key at the place of Server API key . It will work.

Answer 2

OK, i am just shooting in the dark here. Take a look at this line:

Request.Headers.Add(HttpRequestHeader.Authorization, "Authorization: key=AIzaSyCEygavdzrNM3pWNPtvaJXpvW66CKnjH_Y");

Shouldn't it be:

Request.Headers.Add(HttpRequestHeader.Authorization, "key=AIzaSyCEygavdzrNM3pWNPtvaJXpvW66CKnjH_Y");

Since you're telling it this is a Authorization header, there's no need to add 'Authorization: ' again, does it?

Also, make sure the string constant 'HttpRequestHeader.Authorization' is 'Authorization'.
