# 具体遇到的问题
写的代码 按钮按上去没用，然后AS重启了以后就报错了，折腾了两三个小时还是没用，依然错
# 报错信息的截图
Could not load wrapper properties from 'D:\MyApplication\gradle\wrapper\gradle-wrapper.properties'.
# 相关课程内容截图
# 尝试过的解决思路和结果
# 粘贴全部相关代码，切记添加代码注释（请勿截图）
老师帮我看看代码哪里有问题吧

同学你好，报的错不是代码问题，你先排查环境的问题。先重新创建一个project，代码什么的都不要改动看能不能运行起来。如果能运行起来，则表明你的AS升级了，导致原来项目的配置与现环境不匹配导致的。如果还想用原来的项目，你可以对比build.gradle文件，修改一下原来的内容，或者，你把原项目main下的三个文件夹直接复制到新项目中，覆盖新项目内容，就可以使用了。
