Is There Limit Of Android Gcm Push Notification

Is there is any limit of android gcm push notification ? Actually I am getting message that your GCM subscription expired with device ID: .............. I have send just 1000 messa

Solution 1:

No there is no limit as @Pals pointed out but there is a limit on the number of recipients per message. You can send out a message to 1000 users at a time, so if you have more users you'll have to send the message multiple times from your server but to different users each time.

Solution 2:

Your first question: There is no limits.

Your seconds question: Unlike IOS, in android the registration_id will expire for certain reason. (e.g. re-install the app) To be safe, you should update the id to your push server everytime the app starts.
