Nowadays we commonly get this type of error in gradle when we use third party library : Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0-rc02] AndroidManifest.xml:22:18-91 is also present at [androidx.core:core:1.0.0-rc01] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory). Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:5:5-19:19 to override. we get this types of error when library is updated and providing use of AndroidX but we are using old one.
