Image overlap issue over Frame in Xamarin Android

I am trying to build following layout in XAML for Xamarin forms app.

Here is my code

<AbsoluteLayout
        HorizontalOptions="FillAndExpand"
        HeightRequest="350">
        <Frame
            AbsoluteLayout.LayoutFlags="SizeProportional"
            AbsoluteLayout.LayoutBounds="0,0,1,1"
            BackgroundColor="White"
            HasShadow="true"
            CornerRadius="10"
            Margin="20,25,20,25">
            <StackLayout>
            </StackLayout>
        </Frame>
        <Image
            AbsoluteLayout.LayoutFlags="PositionProportional"
            AbsoluteLayout.LayoutBounds="0.5,1,50,50"
            Source=“icon.png”/>
    </AbsoluteLayout>

It works good on IOS but icon image is not shown correctly in android.
Please look at following screenshot.

Please help me to fix!
