错误:链接引用失败。在Android at building

Question

我使用的是两年前开发的Android Studio应用程序，我想继续。

当我尝试构建它时，它出错了：

​

如果我转到"Run build"，它会给我一个日志，里面有下一个有趣的信息：

当我转到main "Build“时，我得到了这个：

Android resource linking failed
D:\myPath\myApp\myName.myApp\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml:1374: error: resource android:attr/preserveIconSpacing is private.
error: failed linking references.

我在找"preserveIconSpacing“和"error:失败的链接引用”，但我没有找到任何有趣的东西。我能尝试什么呢？

编辑:我添加了values.xml (在第392行，它是preserveIconSpacing) values.xml

首先，升级您的构建版本

 buildToolsVersion 

然后在gradle文件中更改以下三项内容

 compileSdkVersion 'your api level'
  minSdkVersion 'your api level'
  targetSdkVersion 'your api level'

还要升级此依赖项

dependencies {
implementation 'com.android.support:appcompat-v7:'your api level''
}
