I am trying to fire a HTTPC post request from Erlang:
httpc:request(post, {"https://android.googleapis.com/gcm/send",[{"Authorization","key=api_key_generated_at_googleaccount"}],[{"Content-Type","application/json"}],Body},[],[])
But every time I fire this request my Erlang shell hangs. Is there any problem in the request?

I think you mixed up the arguments to http:request/4 a bit, in the manual for httpc:
request(Method, Request, HTTPOptions, Options)
Request = request()
request() = {url(), headers()} |
{url(), headers(), content_type(), body()}
content_type() = string()
Above you can see content_type() should be a string() and not [{string(),string()}].
It is easier if to read if you put the whole request() into a variable:
10> inets:start().
ok
11> ssl:start().
ok
12> Body = "some cool json",
12> Request = {"https://android.googleapis.com/gcm/send", [{"Authorization","key=blabla"}], "application/json", Body},
12> httpc:request(post, Request, [], []).
{ok,{{"HTTP/1.1",401,"Unauthorized"},
