android studio导入旧项目后出现窗口上报错提示：

The SDK path
'\Users\cmm\Library\Android\sdk'
does not belong to a directory.

Android Studio will use this Android SDK instead:
'C:\Users\Administrator\AppData\Local\Android\Sdk'
and will modify the project's local.properties file.

错误在哪，我不说多，直接说吧

要改插件与Gradle
一、project的build.gradle中：

classpath 'com.android.tools.build:gradle:x.x.x'

二、gradle\wrapper\gradle-wrapper.properties中：

distributionUrl=https\://services.gradle.org/distributions/gradle-x.x.x-x.zip

三、app的build.gradle中：

    ......
    compileSdkVersion xx
    buildToolsVersion "xxx"
    ......
    targetSdkVersion xx
    ......
implementation 'com.android.support:appcompat-v7:xx.x.x'
    ......
