Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0] [duplicate]

Question

Hi I was working on a Project where I used many dependencies of Libraries. It was working fine but suddenly it has started to report errors. I am new in using Libraries dependencies and I am using Firebase database and storage and also have added google-services.json under app folder. I couldn't understand where the problem lies. Thanks for help in advance

Following is the Error list

`Executing tasks: [:app:assembleDebug]

Answer 1

Try Adding two lines in gradle.properties file:

android.useAndroidX=true
android.enableJetifier=true

These two lines automatically resolved my dependency conflicts between google's files and third party dependencies.

Hope it works for you !
