Hi, in api register method
https://developer.chrome.com/apps/gcm#method-register told that the same registerid will returned each time i call to register method
"Registers the application with GCM. The registration ID will be returned by the callback. If register is called again with the same list of senderIds, the same registration ID will be returned."
Is this true? has some condition for be the same? (not restart chrome, x days lifetime, etc)
Thanks
