Android Question How to solve the delay of the timer?

[Kedrick164]

Hi good day, i'm making a personalized stopwatch, but this have a delay.

I made a test, i start the stopwatch of the w10 app at the same time of my app in the phone. In sixty seconds of the w10 app, the app of the phone have a delay of two seconds, why does this happen and how can i solve it?, thanks in advance

This is the code

Sub Process_Globals

    Dim Timer1 As Timer

End Sub

Sub Globals
  
    Dim lblTime As Label
  
    Dim Time As Double

End Sub

Sub Activity_Create(FirstTime As Boolean)

    Activity.LoadLayout("Start")
    Timer1.Initialize("Timer1", 100)
    Timer1.Enabled = False

    Time = 0

End Sub

Sub Timer1_Tick
  
    Time = Time + 0.1
    lblTime.Text = Round2(Time, 2)

End Sub

I tested this code on my pc (b4j) and on my android and after 360 seconds the phone was 0.5 second faster. Do tests with others w10 applications.

Timers are not 100% exact. You shouldn't track the time like this.

Store the current system time when you start: DateTime.Now.

Tip: Never use Round2.

Sub Timer1_Tick
  
    Dim time As Int = DateTime.Now - GlobalTimeSetWhenStopperWasStarted
    lblTime.Text = $"Time: $0.2{time}"$

End Sub
