问题
Situation is that I sent a notification from my server to 1 million users. Request is in queue at GCM. After triggering the notification from server I found that notification is not correct and it should not be sent. I want to stop it. At that point of time how I can clear/delete GCM queue?
Any suggestion would be really helpful.
