• The user uninstalls/reinstall the app
• The user clears app data.

1-According to google


so don't expect that your token will change frequently
I use FirebaseMessaging service Create to get the token every time the application starts

B4X:

Sub Service_Create
    fm.Initialize("fm")
    fmt=fm.Token
End Sub

2-where you put this code?

Sub Service_Create
    fm.Initialize("fm")
    If fm.Token.Length = 0  Then
        StopService(Me)
        StartServiceAt(Me,DateTime.Now + 200, False)
    End If
End Sub

Why do you need the token? This is not needed in most cases.

There are rare cases when you don't get a token at once. I've added a sleep(0) after fm.initialize which did the trick for me.
