Oval shape clipped when created programmatically

I found the solution on this page: http://www.betaful.com/2012/01/programmatic-shapes-in-android/

In Android, when you draw with a stroke, it draws the center of the stroke at the boundaries of the shape you are drawing. As you can see, the stroke is getting cropped by the boundaries of the image. Luckily, you can perform transformations on a canvas. What we want to do is transform our stroke shape to be slightly smaller than the boundary – and there’s a Matrix operation for that!

matrix.setRectToRect(new RectF(0, 0, canvas.getClipBounds().right, canvas.getClipBounds().bottom),
new RectF(strokeWidth/2, strokeWidth/2, canvas.getClipBounds().right - strokeWidth/2,
    canvas.getClipBounds().bottom - strokeWidth/2),
Matrix.ScaleToFit.FILL);

Edit

... Better and easier solution find in the comment section of the link:

As you can see in the Android docs, a shape Drawable in resources is actually mapped to a GradientDrawable, not a ShapeDrawable:

And so, I've got the following code working perfectly:

GradientDrawable drawable = new GradientDrawable();
drawable.setColor(Color.TRANSPARENT);
drawable.setShape(GradientDrawable.OVAL);
drawable.setStroke((int)dpToPx(2), Color.parseColor("#EEEEEE"));
drawable.setSize((int)dpToPx(240), (int)dpToPx(240));
