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

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

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