集成引入第三方library时出现错误Manifest merger failed : Attribute application@appComponentFactory

集成引入第三方library时出现以下错误

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:5:5-19:19 to override.

这是由于AndroidX包和Android support冲突引起的 （打开AndroidStudio下方Terminal输入命令gradlew :app:dependencies可以看到包结构）

方法1

在AndroidManifest.xml文件中添加android:appComponentFactory=""（可能会解决问题，但不是在根源上解决问题）

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

方法2

1、首先查看build tools（3.2.0以上）， gradle（4.6以上）和依赖库（28.0.0）

classpath 'com.android.tools.build:gradle:3.3.1'

distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.1-all.zip

compileSdkVersion 28
implementation 'com.android.support:appcompat-v7:28.0.0'

2、选择工程右键-->Refactor-->Migrate to Androidx--> Do Refactor

方法3

把项目中依赖Androidx的库转换为Android support
在terminal中执行gradlew :app:dependencies命令查看依赖Androidx的库再去找低版本替换
