I'm working on a project which receive notification from GCM server.
I've got the registration ID from GCM server and i send it to my server application which save it in the database.
My device receive the message but when I try to send another one, the precedent is replaced.
I know that we've 2 types of message:
- Collapsible "send to sync"
- Non-Collapsible
So without changing the name of the message, how can I get two message send at different time?
UPDATE 1:
When my device is offline (for example airport mode activated), I try to send for example 2 messages from my application server to Google server (I read that Google stores all the messages). But when I desactivate this mode, I receive only the last message sent.
I use different collapse_key for different message and I receive all of them (of course when the device online).
Is anybody knows how can I fix this?
