AKA GCM
http://developer.android.com/google/gcm/index.html
Overview
My understanding is this
- Mobile client sends message to GCM via XMPP
- GCM forwards message to 3rd party server (that's me).
- 3rd party server can send messages to clients via GCM server.
Advantages
- Google server can do store and forward so neither mobile nor my server need be online 100% of the time.
- Saves battery by using only one connection for all services with phone.
It is unclear to me the relationship between "GCM" and "GCM Cloud Connection Server" http://developer.android.com/google/gcm/ccs.html CCS is XMPP based. I am coming to the game late, seems like the old way was just HTTP based? Enlighten me please.
It looks like I should be able to use an XMPP client to talk to CCS from my server. Then Google handles the interaction with my phone.
Python - There is a sample on the Google page. http://developer.android.com/google/gcm/ccs.html
It also looks like there are many hoops to jump through and at the moment I don't need this. XMPP for me.
Sample gcm server
Web App that runs in Tomcat
Sends a message to any registered Android devices that says "You got a message".
WebContent/
index.jsp just loads home via webmapping /home
WEB-INF/
lib/
- gcm-server.jar -- sources are at the root level in the gcm code
- json_simple-1.1.jar -- probably a json parser
Servlets
- RegisterServlet -- accepts connections
- UnregisterServlet --
- SendAllMessagesServlet -- sends a message to all registered devices
- HomeServlet - displays existing messages and allows sending a new one
