I am confused a little for which API key should I use for the GCM server. In the documentation it says use android api key, which did not work with me and always gives unauthorized. http://developer.android.com/google/gcm/gs.html I used server key which worked for me, but I am wondering why the documentation says that? Am I doing something wrong?
I saw this post also, but I could not get an answer. GCM Push Server side, which API Key to use?
Thanks for advance.
