[android-developers] Re: NEED HELP!! - Food Menu Order/List Application
Hi,
If you want to maintain small amount of data say settings then go for
preferences and better go for SQlite database to hold the items .and load
the list from data based on SQLite database.

[android-developers] how to optimize reliability of gcm messages on 2G network?
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.
