Question

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?

Answer 1

You need to make sure that the value of the ‘collapse_key’ field in each message is different
