问题
I am using gcm.jar on client side and gcm Zend framework on server side for sending push notification. There are about 100 devices registered for push notification, on firing notification even though I receive successful message, push not getting delivered on some of the devices, May I know what would be the various reasons for failures and how to handle them. Any suggestion will be appreciated,
Thank you in advance.
