Activity Indicator not getting rendered in Absolute Layout

I am trying to show an Activity Indicator in my App for which I have written the following code but the indicator is not getting rendered on the screen. Can somebody please suggest what has gone wrong?

private ActivityIndicator indicator = new ActivityIndicator
{
    HorizontalOptions = LayoutOptions.CenterAndExpand,
    Color = Color.Black,

    IsVisible = false
};



StackLayout stack = new StackLayout
                {
                    VerticalOptions=LayoutOptions.FillAndExpand,
                    HorizontalOptions=LayoutOptions.FillAndExpand,
                    Padding=0,
                    Spacing=0,
                };

                AbsoluteLayout absolute = new AbsoluteLayout
                {
                    VerticalOptions = LayoutOptions.FillAndExpand,
                    HorizontalOptions = LayoutOptions.FillAndExpand,
                };


  stack.Children.Add(map);
  stack.Children.Add(browser);

AbsoluteLayout.SetLayoutFlags(stack, AbsoluteLayoutFlags.PositionProportional);
AbsoluteLayout.SetLayoutBounds(stack, new Rectangle(0f, 0f, AbsoluteLayout.AutoSize, AbsoluteLayout.AutoSize));

AbsoluteLayout.SetLayoutFlags(indicator, AbsoluteLayoutFlags.PositionProportional);
AbsoluteLayout.SetLayoutBounds(indicator, new Rectangle(0.5f, 0.5f, AbsoluteLayout.AutoSize, AbsoluteLayout.AutoSize));


  absolute.Children.Add(indicator);
  absolute.Children.Add(stack);



*//When Some activity occurs.....Indicator is shown like this*

 indicator.SetBinding(ActivityIndicator.IsVisibleProperty, "IsBusy", BindingMode.OneWay);
            indicator.SetBinding(ActivityIndicator.IsRunningProperty, "IsBusy", BindingMode.OneWay);
            indicator.IsRunning = true;
            indicator.IsVisible = true;

Try this

AbsoluteLayout.SetLayoutBounds(stack, new Rectangle(0f, 0f, 1f, 1f));
AbsoluteLayout.SetLayoutBounds(indicator, new Rectangle(0.5f, 0.5f, -1f, -1f));
AbsoluteLayout.SetLayoutFlags(stack, AbsoluteLayoutFlags.All);

Add the indicator after the stack. absolute.Children.Add(indicator) after absolute.Children.Add(stack);

Check If your IsVisible is true.
