android-studio - android.useAndroidX 属性未启用，为什么要启用？

Question

我遇到了 androidDx 库的问题，所以当我将 shimmer 库添加到我的项目或 glide 照片库时，或者当我将 google play 服务广告更新到 19.1.0 时，它一直要求我启用 android dx

ERROR: This project uses AndroidX dependencies, but the 'android.useAndroidX' property is not enabled. Set this property to true in the gradle.properties file and retry. The following AndroidX dependencies are detected: androidx.annotation:annotation:1.0.1

但我不想启用它，还是必须启用它？

这是我的gradle文件

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "folo.new.test.my"
        minSdkVersion 15
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
        debug {
            multiDexEnabled true
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:exifinterface:28.0.0'
