Android Question Is there a way to invert a clip path?

Sub Activity_Create(FirstTime As Boolean)
   Dim cvs As Canvas
   cvs.Initialize(Activity)
   Dim circle As Path
   circle.Initialize(50%x, 50%y)
   Dim radius As Float = 100dip
   PathAddCircle(circle, 50%x, 50%y, radius)
   Dim fullScreen As Path
   fullScreen.Initialize(0, 0)
   fullScreen.LineTo(100%x, 0)
   fullScreen.LineTo(100%x, 100%y)
   fullScreen.LineTo(0, 100%y)
   Dim p As Path = OpPath(fullScreen, circle, "DIFFERENCE")
   cvs.ClipPath(p)
   
   Dim dest As Rect
   dest.Initialize(0, 0, 100%x, 100%y)
   cvs.DrawBitmap(LoadBitmap(File.DirAssets, "b4a.png"), Null, dest)
End Sub

Sub OpPath(p1 As Path, p2 As Path, Op As String) As Path
   Dim jo As JavaObject = p1
   Dim success As Boolean = jo.RunMethod("op", Array(p2, Op))
   Log($"Success: ${success}"$)
   Return p1   
End Sub

Sub PathAddCircle(path As Path, x As Float, y As Float, radius As Float)
  Dim jo As JavaObject = path
  jo.RunMethod("addCircle", Array(x, y, radius, "CW"))
End Sub
