Android: Manifest merger failed CoreComponentFactory

Question

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 element at AndroidManifest.xml:6:5-33:19 to override.

My code

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="midhilaj.in">

I also ran into the same problem and after a bit of search i found this issue here: https://github.com/JakeWharton/butterknife/issues/1429

Here the creator of library has suggested that either you migrate to androidX or downgrade the library version to the compatible one.For now i am using following:

    implementation 'com.jakewharton:butterknife:8.8.0'
    annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.0'
