android - 工具 :replace="android:appComponentFactory Error

Question

当我尝试运行应用程序时，我收到以下错误。我该怎么做才能解决这个问题？

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). Suggestion: add 'tools:replace="android:appComponentFactory"' to element at AndroidManifest.xml:9:5-31:19 to override.

See ... for more information about the manifest merger.

FAILURE: Build failed with an exception.

What went wrong: Execution failed for task ':app:processDebugManifest'. 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).
