Android Question (solved)I have to restart the application so that the firebasenotifications messages start to arrive

Hi
For some reason in some phone I must restart the application so that the messages of firebasenotifications begin to arrive.
I have other phone that the messages come at once to run the application for the first time, but others I must restart the application and then everything works correctly. which may be?

Thanks for your time

Mostly due to energy saving options (app is stopped then including the fcm service)

The app is expected to start when a message arrives.
What you describe sounds like an OS bug.

When I started with FCM I had similar problems like you. Huawei had a whitelist. Only known apps were allowed to run in the background. Even WhatsApp did not show any notifications. You had to add it (see energy savings) to be allowed to run in the background by default.

What happens: Your app is fully stopped (and the FCM service, too) and can't receive any FCM messages. So add your app to the whitelist (options, energy savings...)

excellent, I'm going to do a review to see if I get it within the options, thanks for your help

May I know is it because we need to subscribe to a topic and this setting will only applied after the app restarted?

I think it is an error of certain phones as Erel says, because in other phones the notifications work immediately.....
