I am using 2g network for Instant messaging .with payload less than 2kb.. In 3g network success rate of receiving gcm messages is 10/10 with out queueing of messages in gcm messaged in GCM server.
In 2G network " here Is the problem" 5/10 messages are received instantly other 5 goes in to queue I n GCM server .. My question is As Google queue messages on gcm server When phone is idle. 1 is there a callback to device when gcm message is queue in server. 2 is there way to optimize gcm messages on 2g network 3 when does gcm expire. 4 or is there better way of handling gcm message for 2G -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
