这是我的安卓build.gradle

buildscript {
    repositories {
        maven {
            url "https://maven.google.com"
        }
        jcenter()
    }
    dependencies {

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.安卓.tools.build:gradle:3.0.1'
    }
}

allprojects {
    repositories {
        maven {
            url "https://maven.google.com"
        }
        jcenter()
    }
    //This replaces project.properties w.r.t. build settings
    project.ext {
      defaultBuildToolsVersion="27.0.1" //String
      defaultMinSdkVersion=19 //Integer - Minimum requirement is Android 4.4
      defaultTargetSdkVersion=27 //Integer - We ALWAYS target the latest by default
      defaultCompileSdkVersion=27 //Integer - We ALWAYS compile with the latest by default
    }
}

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

以下是我所做的事情：

我将defaultCompileSdkVersion从27更改为28相同的结果

我补充说

configurations.all {
    resolutionStrategy {
        force 'com.安卓.support:support-v4:27.1.0'
    }
}

在build.gradle的底部

我删除了构建并重新安装，同样的错误

我别无选择

提前谢谢你的帮助
