FCM Message and data

[chengqw]

I've encountered a few issues during development and would appreciate your confirmation:

1. When an FCM notification is triggered, it launches the application process. Is this normal? Launching the application in data mode is understandable.

2. Does the notification mode have a higher priority than data mode for push notifications? What is the general strategy here? Is it possible that the notification mode is more reliable?

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

To add to the previous question: In notification mode, if starting the FCM service fails, can GMS still call the system interface to create notification pop-ups to ensure a high reach rate?

Could you please confirm if this mechanism is in place? Does it require configuration fields?
