[Android] Didn’t find class “android.support.v4.app.CoreComponentFactory”

to your manifest application

<application
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    tools:replace="android:appComponentFactory"
    android:appComponentFactory="@string/action_settings">

某包比如：

implementation “com.github.hotchemi:permissionsdispatcher:4.0.0”
Error:
    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 element at AndroidManifest.xml:15:2-101:16 to override.

按照其建議加上 tools:replace=”android:appComponentFactory” 後依然報錯：

Error:
    tools:replace specified at line:14 for attribute android:appComponentFactory, but no new value specified
E:\Android\Job\TestDemoProject\github\BaseApplication\BaseApplication\app\src\main\AndroidManifest.xml Error:
    Validation failed, exiting

解決：

<application
  tools:replace="android:appComponentFactory" //除了這行之外
  android:appComponentFactory="任意字符"  //還要加上這一行
