Program type already present: android.support.v4.graphics.drawable.IconCompatParcelizer

[shenbuqingyun]

Manifest merger failed : Attribute application@appComponentFactory

[shenbuqingyun]

Suggestion: add 'tools:replace="android:appComponentFactory"' to element

[jaredrummler]

Are you sure this is related to the library? It isn't using IconCompatParcelizer

Tengo el mismo Problema

---- 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).

I also meet this question.I have solved it. My compileSdkVersion is 28.
You only chose Refactor-Migrate to AndroidX.
Done.
