发现问题最近在项目中用到了canvas的toDataURL方法来获取图片的base64格式数据，用以上传到后台。
由于之前也遇到过canvas被跨域图片污染不能获取数据的坑，因此这回一开始就机智的把crossOrigin属性值加上，代码大概如下：constcanvas=document.createElement("canvas");constcontext=canvas.getContext("2d");context.fillStyle="black";context.fillRect(0,0,canvas.width,canvas.h

Android徽章BadgeUtil提供了静态实用程序方法来设置Launcher上的“徽章计数”（由LG，Samsung）。
屏幕截图从三星GalaxyS3捕获从三星GalaxyS4捕获从LGG3捕获API用法BadgeUtil.setBadgeCount(Context,count);BadgeUtil.resetBadgeCount(Context);局限性目前，它可以在Android4.0上运行。
但是某些从制造商处发布的设备无法正常工作。
您应该在首次启动时重置徽章计数，因为即使卸载应用程序后，旧计数也可以保存。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
