Crash in some strange case of drawing with no points

[RunYouCleverBoy]

/**
 * Setup circles on a screen
 */
private void drawLineToTouchPoint(Canvas canvas) {
    if (touchPoint.height() > 0 && touchPoint.width() > 0) {
        drawLine(canvas, circles[connectionOrder.get(connectionOrder.size() - 1)], touchPoint);
    }
}

Forgot to check that !connectionOrder.isEmpty()
It may crash if the view refreshes when you your finger on, and it's blank.
