清单合并失败：[androidx.core:core:1.0.1] AndroidManifest.xml:22:18-86 中的属性 application@appComponentFactory value=(androidx.core.app.CoreComponentFactory) 也存在于 [com.android.support :support-compat:28.0.0] AndroidManifest.xml:22:18-91 值=(android.support.v4.app.CoreComponentFactory)。建议：将 'tools:replace="android:appComponentFactory"' 添加到 AndroidManifest.xml:17:5-122:19 的元素以覆盖。
