android - GCM Cloud Connection Server - how to start using it? -

-

i want use gcm cloud connection server. far have read gcm cloud connection server , i'm confused. @ top of page there link form.

my question is:

do need fill , wait response form google saying enabled gcm ccs project, or can start coding without filling form?

if answer need fill form, there restrictions can use it? because did fill sample data (confirmed id of project google console) , got no answer.

you can start coding whenever wish, until google whitelist api project id (the 1 should specify in sign-up form), new features (ccs , user notifications) won't work you.
