C2DM confirmation e-mail but no id

I've received a confirmation e-mail after the registration of my Android app on this address http://code.google.com/android/c2dm/signup.html. But i've not the开发者_运维技巧 registration id. How do i get this registration id, if it's not by subscribing on this page ? Or maybe, I have to wait longer ?

Thanks in advance

U wont get any registration id in your mail. U need to do those things in the client application. The registration id will be unique for the device which the google will assign. That may also changes periodically(refreshed by the google). Go through this link C2DM article. So that u can get a clear picture of the C2DM.
