title: How to Parse send push without gcm registration?
body: <p>While implementing push with Parse, I didn't use anything related to Google Cloud Messaging. I didn't open Google dev console and switch on GCM messaging, also I didn't get any sender ID and I didn't register devices to obtain registration ID, however Parse could send push. I wonder Parse uses its own socket? In Parse Android source code, I couldn't catch anything related to this. Now all Parse migrating services need GCM registration ID including with Parse's own open source push backend solution. Can someone give detailed information about this?</p>
