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.
如何解决此错误。

gradel文件
apply plugin: 'com.android.application'

}
别忘了添加
android.useAndroidX=true
android.enableJetifier=true
到您的gradle.properties。当我上一台新机器时,我总是会忘记这一点,因为gradle.properties不在源代码管理中。如果在这种情况下出现明智的错误,那就太好了。
清单:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.niks.abc">
<application
android:allowBackup="true"

希望这会对您有所帮助。
