清单合并对于appComponentFactory失败 [英] Manifest Merger fails for appComponentFactory

问题描述

使用Google所谓的Material Design 2.0时，您需要添加

Using Google's so called Material Design 2.0 requires you to add

implementation 'com.google.android.material:material:1.0.0-rc01'

在应用Gradle中，其中还包括

in the app Gradle which also includes

implementation 'com.android.support:appcompat-v7:28.0.0-rc02'    

显示冲突

这是日志所说的

Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0-rc02] AndroidManifest.xml:22:18-91   

is also present at [androidx.core:core:1.0.0-rc01] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).     Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:5:5-19:19 to override.

即使将其添加到清单中，它也会显示 清单合并失败，并出现多个错误

Even after adding that to the Manifest it shows Manifest Merger failed with multiple error
