Merged Manifest

Manifest merger failed : Attribute application@appComponentFactory value=(androidx.core.app.CoreComponentFactory) from [androidx.core:core:1.0.0] AndroidManifest.xml:22:18-86 is also present at [com.android.support:support-compat:28.0.0] AndroidManifest.xml:22:18-91 value=(android.support.v4.app.CoreComponentFactory). Suggestion: add 'tools:replace="android:appComponentFactory"' to element at AndroidManifest.xml:31:5-163:19 to override.

 

Solution

gradle.properties에 아래 두 줄 추가

android.useAndroidX=true
