将项目SDK更改为android pie时Android Studio同步错误

Question

我的项目同步时出现此错误:

Android resource linking failed

构建.gradle:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.2.71'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

为什么会这样？我的项目一直很好，直到我发现我的 android 手机在 Android Oreo 上，而我的项目是 Android Pie，所以我下载了 Oreo SDK 并更改了项目 min 和 target SDK。这破坏了一切，我无法运行它。

Answer 1

Why could this be? My project was fine up until I found that my android phone was on Android Oreo, and my project was Android Pie so I downloaded the Oreo SDK and changed the projects min and target SDK. And that broke everything and I can't run it.

看起来编译 sdk 版本和支持库版本不匹配。假设基于您上面提到的内容，因为您可能错过了更新与编译 sdk 版本匹配的支持库版本。
