I have a problem with the suggestion of adding 'tools: replace = "android: appComponentFactory" to the xml file

Question

I have a problem with my android studio with the following information;

console

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:8:5-60:19 to override.

I have tried adding the suggestion to my xml file, but almost all of my manifest files have errors

apply plugin: 'com.android.application'

</manifest>

The simple solution is just migrate to AndroidX . Otherwise you will end up changing library versions over and over . — ADM, Jul 23 '19 at 03:51

In your manifest add tools:replace="android:appComponentFactory" in the application tag like below

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

try this. seems google play service is not implemented.

 implementation 'com.google.firebase:firebase-core:17.+'
 implementation 'com.google.firebase:firebase-ads:17.+'

Add Google Play Service at the last line

apply plugin: 'com.google.gms.google-services'

You have two solutions to this problem.

First

Migrate your project into AndroidX

Second

Add these lines inside your application tag like below.

tools:replace="android:appComponentFactory"

android:appComponentFactory="whateverString"

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

I have a problem with the suggestion of adding 'tools: replace = "android: appComponentFactory" to the xml file
