Java MessageQueue回调中出现异常：HandlerReceiveCallback洪水填充算法

我正在Android中创建一个麒麟彩色应用程序，用选定的颜色给触摸过的白色像素上色。我在下面的算法中找到了如何从可绘制的图像中创建位图，并获得触摸区域的点x、y方向和targetColor，以替换为replacementColor

以下是我的算法代码：

  public void floodFill(Bitmap  image, Point node, int targetColor,
                          int replacementColor) {
        int width = image.getWidth();
        int height = image.getHeight();
        int target = targetColor;
        int replacement = replacementColor;
        if (target != replacement) {
            Queue<Point> queue = new LinkedList<Point>();
            do {
                int x = node.x;
                int y = node.y;
                while (x > 0 && image.getPixel(x - 1, y) == target) {
                    x--;
                }
                boolean spanUp = false;
                boolean spanDown = false;
                while (x < width && image.getPixel(x, y) == target) {
                    image.setPixel(x, y, replacement);
                    if (!spanUp && y > 0 && image.getPixel(x, y - 1) == target) {
                        queue.add(new Point(x, y - 1));
                        spanUp = true;
                    } else if (spanUp && y > 0
                            && image.getPixel(x, y - 1) != target) {
                        spanUp = false;
                    }
                    if (!spanDown && y < height - 1
                            && image.getPixel(x, y + 1) == target) {
                        queue.add(new Point(x, y + 1));
                        spanDown = true;
                    } else if (spanDown && y < height - 1
                            && image.getPixel(x, y + 1) != target) {
                        spanDown = false;
                    }
                    x++;
                }
            } while ((node = queue.poll()) != null);
        }
    }

但我得到了这个错误：
