Did you follow step 2?

2. Add a Service named FirebaseMessaging to your app (must be this name)

Hi An chi,

I got it thank you very much.

This is my problem now, each devices that will install my app will have defferent unique tokens which is i used to send a message using PHP.

Do you have any suggestions or samples how can i store all devices unique tokens and send them all message at once? or devices will automatically subscribe then automatically when i send message via php all of the devices will receive?

Thanks
