Program type already present: android.support.v4.app.INotificationSideChannel$Stub$Proxy

Question

I know it could look like This Question but I could not fix it with the solution proposed and I could not comment on it too. The Error is :

Program type already present: 
android.support.v4.app.INotificationSideChannel$Stub$Proxy
Message{kind=ERROR, text=Program type already present: 
android.support.v4.app.INotificationSideChannel$Stub$Proxy, sources=[Unknown 
source file], tool name=Optional.of(D8)}

I'm trying to create an app using firebase there's is my gradle file

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
    minSdkVersion 27
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
aaptOptions {
    noCompress "tflite"
}
}

dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'androidx.appcompat:appcompat:1.0.0-rc01'
implementation 'androidx.constraintlayout:constraintlayout:1.1.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.1.0-alpha4'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-alpha4'
implementation 'com.google.android.material:material:1.0.0-rc01'
implementation 'androidx.cardview:cardview:1.0.0-rc01'

// ML Kit dependencies
implementation 'com.google.firebase:firebase-core:16.0.1'
implementation 'com.google.firebase:firebase-ml-vision:17.0.0'
}
apply plugin: 'com.google.gms.google-services'

I pass over every file to be sure the import was good, I Also add

android.useAndroidX = true
android.enableJetifier = false

There's my Project Gradle file :

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

buildscript {

repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.1.4'
    classpath 'com.google.gms:google-services:4.1.0'


    // 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
}

I use Android Studio 3.1.4

This happened to me when I tried to migrate to Android X.The reason behind is that not all libraries have been migrated to Android X.

• You may manually remove dependencies. : Try to see all dependencies and find out the conflicting one. You may use Gradle View plugin for Android Studio or use class navigation from menu. (In android Studio: Navigation -> class; Now a search box appears and tick 'include non project items'; paste the whole class name creating error and search now; Find out the class having this dependency and remove manually!). Please check if you have any import statements left in files which uses the non AndoirdX dependencies still. If yes, please remove them too.

or

• In Android studio, Refractor -> Migrate to AndroidX.

or alternatively(manual way)

• add following to gradle.properties .

   android.useAndroidX=true
   android.enableJetifier=true

This makes Android Studio to migrate all dependencies. For more info please check here

I have a similar problem. In my case, it was because I am using Glide library and androidx. This solution works for me:

1. Set enableJetifier value to true
2. Update Gradle build tool to 3.3.0-alpha08 with Gradle version 4.9
