Did you have a look at the ABExtDrawing library?
It includes the entire Android Canvas functionalities.

The canvas libraries will not give you the undo function.
if you want to be able to go back many steps then save each drawing bitmap as a file with a number before drawing:
When going back load the previous file and reduce the count:

Sub Globals
    Private canvas1 As Canvas
    Private count As Int = 0
End Sub

....
' draw, save the bitmap before drawing

' go back when you need using sub back_draw

....
Sub save_drawing
    Dim Out As OutputStream
    Out = File.OpenOutput(File.DirRootExternal, "save" & count & .png", False)
    canvas1.Bitmap.WriteToStream(Out, 100, "PNG")
    Out.Close
    count = count + 1
End Sub

Sub back_draw
    count = Max(count - 1, 0)
    canvas1.Bitmap.Initialize(File.DirRootExternal, "save" & count & ".png")
End Sub
