Android 如何解决清单合并失败错误

我正在使用firebase构建一个familyGps跟踪器，我发现以下错误：

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:9:5-31:19 to override.

这是因为它隐式使用了androidX库，这与支持库28.0.0冲突。您需要将android image cropper版本降级为或在项目中使用androidX。

获取此错误：清单合并失败：属性application@appComponentFactory[com.android.support:support compat:28.0.0]AndroidManifest.xml:22:18-91中的value=（android.support.v4.app.CoreComponentFactory）也出现在[androidx.core:core:1.0.0]AndroidManifest.xml:22:18-86 value=（androidx.core.app.CoreComponentFactory）。建议：在AndroidManifest.xml:9:5-31:19处的元素中添加'tools:replace=“android:appComponentFactory”'以覆盖。
