Hey Michi,
I realized that the code I pointed you to could be a bit confusing and also
contains a small bug.

I wrote this gist based on the quickstart example. Basically we register to
2 channels : mail and news, we store the channelID and map that with a
String containing the service name, then in the onNotification we check
which service to call :

Hope this example will make more sense !

Seb
