Sub Activity_Resume

timerInter.Enabled=True

1. Please use [code]code here...[/code] tags when posting code.
2. I guess that the timer was not initialized or initialized with an interval of 0.

timer is initialized in Activity_Create

I don't know if this is the cause of this error, however it is a mistake to initialize the timer when FirstTime is not true. It will result in multiple timers being created.

powerino · Aug 13, 2018

ok, and what do you advise me to do to solve the problem? thank you

As Erel already wrote, you should only initialize the timers if FirstTime is true.

B4X:

if FirstTime then
    '1000 = 1 secondo
    timer1.Initialize("timer1", 1000)

    'per reclame interstitial
    timerInter.Initialize("timerInter",5000)
end if

Obviously you are doing something wrong. You can upload your project, or better a small project that demonstrates the problem.

You are still initializing one of your timer multiple times.

Try to initialize both timers only ones

B4X:

If FirstTime Then
        timer1.Initialize("timer1", 1000)
        'per reclame interstitial
        timerInter.Initialize("timerInter", 5000)
End If

timer1 I use it for other things, it's not for the banner

You can upload your project, or better a small project that demonstrates the problem.

You should not post your code but upload your project as a zip file.

powerino · Aug 13, 2018

file is too large
sorry

DonManfred · Aug 13, 2018

Upload it at dropbox/drive/whereever and post a downloadlink here
