FYI Android developers:
following C2DM deprecation by Google we have scheduled an update to QuickBlox infrastructure supporting GCM push notifications for Android. The release (along with other features and updates) is planned for 24th of July.
You should be able to use C2DM in your apps for a while unless you have registered after C2DM has been deprecated.
Please contact us if you want to join beta testers team to test GCM support before we officially release it.
