Manifest merger failed : Attribute application@appComponentFactory updating Firebase libraries

Question

I am trying to add firebase in my project but when I implement \'com.google.firebase:firebase-messaging:19.0.0\' and \'com.google.firebase:firebase-core:1

Answer 1

With new release, libraries are migrated from the Android Support Libraries to the Jetpack (AndroidX) Libraries.

The updated libraries will not work unless you make the following changes in your app:

• Upgrade com.android.tools.build:gradle to v3.2.1 or later.

• Upgrade compileSdkVersion to 28 or later.

• Update your app to use Jetpack (AndroidX); follow the instructions in Migrating to AndroidX.

Method-1 :

add this two in your gradle.properties File, without updating anything

android.useAndroidX=true
android.enableJetifier=true

Method-2

if Method-1 doesn't solve your problem do one thing if you are using android studio version 3.2 or higher go to Refactor>Migrate to AndroidX...
