Android Question FLP, speed never return to zero

[Mostez]

I use this FLP code for tracking, it seems that it works ok, but speed never return to zero when vehicle stopped, I always get the last updated speed say 20, and it never changed unless the vehicle move again, any ideas to fix that?

TIA

Private Sub flp_LocationChanged (Location1 As Location)
    CallSubDelayed2(Home,"Update",Location1)
    If DateTime.Now > LastUpdateTime + 20 * DateTime.TicksPerSecond Then
        Dim GPStext As String = "Location: " & $"$2.5{Location1.Latitude},$2.5{Location1.Longitude}"$ & " Speed kmh: " & (Location1.Speed * 3.6)
        MyLocation.Info.RefNumber = St.GetRandomID
        MyLocation.Info.Latitude = Location1.Latitude
        MyLocation.Info.Longitude = Location1.Longitude
        MyLocation.Info.Speed = Location1.Speed 'never return to zero if vehicle stopped
        MyLocation.Info.DeviceID = Di
        MyLocation.Info.PhoneNumber = ""
        Wait For (MyLocation.Save) complete (Saved As Boolean)
        
        If Not(Saved) Then
            MyLocation.LogEvent(GPStext)
        End If
        Dim n As Notification = CreateNotification(GPStext)
        n.Notify(nid)
        LastUpdateTime = DateTime.Now
    End If
End Sub

Private Sub CreateLocationRequest() As LocationRequest
    Dim lr As LocationRequest
    lr.Initialize
    lr.SetSmallestDisplacement(10) '10 meters
    lr.SetInterval(1000)
    lr.SetFastestInterval(lr.GetInterval / 2)
    lr.SetPriority(lr.Priority.PRIORITY_HIGH_ACCURACY)
    Return lr
End Sub

You are probably skipping that important update as you are only checking updates every 20 seconds.

You need to change the logic.

test:

not use or set to zero

lr.SetSmallestDisplacement(0) '10 meters

• SetSmallestDisplacement

  (SmallestDisplacementMeters As Float) As LocationRequest
  Set the minimum displacement between location updates in meters.
  By default this is 0.
