Hi
My B4A app has two activities, one of which has a timer, which executes its subroutine every 1 sec. The problem is that when I am in the other activity, the timer does not stop, and every second the program returns to the timer activity and executes its subroutine.
Can everyone know the solution?

- Switch to B4XPages

or

- Stop the time when you reach Activity_Pause. Start the timer in Activity_Resume

B4X: 
Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Activity.LoadLayout("Layout1")
    timer1.Initialize("Timer",1000)
End Sub
Sub Activity_Pause (UserClosed As Boolean)
    timer1.Enabled = False
End Sub
Sub Activity_Resume
    timer1.Enabled = True
End Sub
Sub Timer_Tick
    Log($"Timer-Tick"$)
End Sub

When you switch to second activity the timer ill be stopped. When you come back to actitiy 1 it will be restartet...

How I can replace the service with a b4xpage?

Not at all, because a service is a service and not an activity.
But since 2023 it is recommended to stop using a service and switch to receiver

Receivers and Services in 2023+

In the early days of Android services were simple to use and powerful. They allowed doing all kinds of things in the backgrounds with very few restrictions. That's not the case with newer versions of Android. With a few exceptions (that aren't 100% reliable), the only use case for services is to...
