'android.useAndroidX property is not enabled, why it should be?

I am having an issue with androiDx libraries, so when I am adding shimmer library into my projects or glide photo library or when i update the google play services ads to 19.1.0 it keeps asking me to enable 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

but I don't want to enable it, or is it a must?

this is my gradle file

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'

add this line of code into your gradel.properties file.

android.useAndroidX=true

if you add androidX dependencies, it will work only when you set its property to true otherwise it will not working.
