[Android] How to remove NativeGraphicsView from memory

I have implemented my custom view with NativeGraphicsView. 

public partial class MyViewHandler : ViewHandler<IMyView, NativeGraphicsView>
{

protected override NativeGraphicsView CreateNativeView()
{
return new NativeGraphicsView(Context, VirtualView);
}

public void Invalidate()
{
this.NativeView?.Invalidate();
}


}

I have checked my view in navigation page. All are working fine. When I come back from my view page. Still NativeGraphicsView holding in memory. I have ensured this in android studio. Please find the android snap in attachment.
