004-AndroidStudio报错Manifest merger failed : Attribute application@appComponentFactory value=(android.sup

在引入 库文件时候，AS报错

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).
Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:5:5-20:19 to override.

各种 尝试后，发现 原来 AS早已经给出提示

 

在清单文件 添加如下代码

<application

...
android:theme="@style/AppTheme"

android:appComponentFactory=""
tools:replace="android:appComponentFactory">
