1) going over the MessageHandler interface ([1]), am I right that the "onError()" and "onDeleteMessage()" methods are only relevant for the "device to cloud" case ?
2) I know it's early work, but I was wondering if we should (later) rename the 'AGPushMessageReceiver' class ([2]).
Not sure on a better name, but the AG prefix seems a little odd :) Perhaps:
* AeroGearPushMessageReceiver
* GCMMessageReceiver (since this is really "only" GCM based push messaging)
* AeroGearGCMMessageReceiver
If folks agree on a later rename, I'd create a JIRA to track this ;-)
