IllegalArgumentException: Invalid Region.Op - only INTERSECT and DIFFERENCE are allowed 解决办法

Invalid Region.Op - only INTERSECT and DIFFERENCE are allowed 解决办法

将 destCanvas.clipRect(clipRect, Region.Op.REPLACE);替换为以下代码：

            if(Build.VERSION.SDK_INT >= 26){
                destCanvas.clipRect(clipRect);
            }else {
                destCanvas.clipRect(clipRect, Region.Op.REPLACE);
            }

异常log：
