Manifest merger failed error in Android gradle

I am getting manifest merger failed error. I have tried most suggested way to fix below error with dependency but unable to resolve.

Below is my Gradle file

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.plainnotes"
        minSdkVersion 15
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        vectorDrawables.useSupportLibrary = true
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.support:design:28.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    // additional libraries
    implementation 'androidx.lifecycle:lifecycle-extensions:2.0.0-alpha1'
    implementation 'androidx.room:room-runtime:2.1.0-alpha03'
    annotationProcessor "androidx.room:room-compiler:2.1.0-alpha03"
    implementation 'com.jakewharton:butterknife:10.0.0'
    annotationProcessor 'com.jakewharton:butterknife-compiler:10.0.0'
}

This is the Error message that I received

Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91
    is also present at [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
    Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:5:5-22:19 to override.

It because you are using a different library for android. Made refactor to AndroidX packages for all library

With this

implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:design:28.0.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

// additional libraries
implementation 'androidx.lifecycle:lifecycle-extensions:2.0.0-alpha1'
implementation 'androidx.room:room-runtime:2.1.0-alpha03'
annotationProcessor "androidx.room:room-compiler:2.1.0-alpha03"
implementation 'com.jakewharton:butterknife:10.0.0'
annotationProcessor 'com.jakewharton:butterknife-compiler:10.0.0'

to this

//Android support libraries.
    implementation 'androidx.appcompat:appcompat:1.0.0'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    implementation 'com.google.android.material:material:1.0.0'
    implementation 'androidx.recyclerview:recyclerview:1.0.0'

    implementation 'androidx.cardview:cardview:1.0.0'
    implementation 'androidx.multidex:multidex:2.0.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha2'

As of Support Library and AndroidX Library are diffrent one. So use only one type of library.

You are mixing new androidx package with older version of android support library. You can find a guide and new androidx package on following link https://developer.android.com/jetpack/androidx/migrate

I had a similar problem. Two lines in gradle.properties file:

android.useAndroidX=true
android.enableJetifier=true

and add this in manifest

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools"
package="your.package.uri">

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    tools:replace="android:appComponentFactory"
    android:appComponentFactory="androidx">
