Android Question calculate the area of a polygon

[hanslieb]

Hello,

hope someone can point me in the right direction.

For my App i need to have a function that calculates the area that is drawn by each single point by customes touch on the screen.

The area is drawn in a canvas object by using :

MyCanvas.drawpath(Path, Colors.white, True, 5dip)
MyCanvas.ClipPath(Path)

I have a reference messaerment for a line.
i need to have the result in square mllimeters.

Any help would be nice.

Thanks in advance
