Android Question Firebase push messages: first is auto-cancelled

[peacemaker]

HI, All

I know the pre-history that app in "STOPPED" stated cannot receive any pushes.
If app is started - pushes are received OK, any next.

But if to close it in the recent apps list - it's not fully stopped, event "fm_MessageArrived (Message As RemoteMessage)" is fired (and it makes a Notification), but the sound is momentally interrupted and the Notification is removed.

Second push message is the same arrived, but no problem with Notification - it exists and after tapping the needed activity is open OK.

Who also found ? Why and how to solve ?

it's not fully stopped

The service starts automatically when a message arrives

is fired (and it makes a Notification), but the sound is momentally interrupted and the Notification is removed.

Without seeing your code: It looks like the app crashes at the time. Please check the logs (unfiltered) and see if there's a exception. If so, debug where it happens.

Maybe you refer an uninitialized object. The first time notification crashes, you init object and then the next notification is succesful. You should be sure everytime you execute the sub that every object is fully initialized. I had this issue in my last APP.
Ciao!

It looks like the app crashes at the time. Please check the logs (unfiltered).

Seems, you are right. There is some error in the unfiltered log, but i cannot catch it - the log is very fastly overloaded and first log lines are cleared.

Ha, solved: there was another place where Notification with id=1 was cancelled.
But another trouble is found.
