Manifest merger failed : Attribute [email protected] value=

问题：
Manifest merger failed : Attribute [email protected] 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:9:5-34:19 to override.
出现这种问题一般是support 支持库的版本问题，统一版本就行了；我遇到的是在做flutter混编的时候，AndroidX与support支持库同事存在导致的问题，当然也是应为版本问题
