Java ic_launcher_foregroude.xml在gradle构建时查找多个属性时遇到问题

我刚从AndroidStudio 2.1升级到稳定的3.0，在做一个新项目时出错（我也是AndroidStudio的新手：D） 下面是我得到的错误

错误：（7）在包“android”中找不到属性“fillType”的资源标识符

错误：（28）在包“android”中找不到属性“fillType”的资源标识符

错误：（13）在包“android”中找不到属性“endX”的资源标识符

错误：（13）在包“android”中找不到属性“startX”的资源标识符

错误：（19）在包“android”中找不到属性“offset”的资源标识符

还有几个例外

错误：java.util.concurrent.ExecutionException:com.android.ide.common.process.ProcessException:执行进程E:\AndroidSDK\build tools\27.0.1\aapt.exe（带参数）时出错{package-f--no crunch-ie:\AndroidSDK\platforms\android-23\android.jar-M\？\C:\Users\ShaD iLiX\AndroidStudioProjects\Test1\app\build\intermediates\manifests\manifest.xml-S C:\Users\ShaD iLiX\AndroidStudioProjects\Test1\app\build\mediates\merged\debug-M-J\？\C:\Users\ShaD iLiX\AndroidStudioProjects\Test1\app\build\生成的\source\r\debug-F C:\Users\ShaD iLiX\AndroidStudioProjects\Test1\app\build\intermediates\res\debug\resources-debug.ap \--custom package com.example.shadilix.Test1-0 apk--输出文本符号\？\C:\Users\ShaD iLiX\AndroidStudioProjects\Test1\app\build\intermediates\symbols\debug--无版本向量}

清理构建和/或重新启动并使其无效可能会解决问题

我昨天在复制原始项目时遇到了这个问题。 我找到的解决方案是在单独的位置创建原始项目的zip文件，然后打开/构建它

---

出现上述问题是因为我猜它找不到ic_launcher_后台所需的文件。

您有没有找到解决此错误的方法？我也面临同样的错误。
