当我更新android studio时出现此错误：

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:18:5-91:19 to override.

我也有这个错误，但是在gradle文件中::::

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 28.0.0, 23.0.1. Examples include com.android.support:animated-vector-drawable:28.0.0 and com.android.support:support-v4:23.0.1 more... (Ctrl+F1

您同时使用了支持库和androidx库，但您做不到。

检查Firebase库的official release notes：

-----------------------------------------------------------------
|  Service        |  Gradle dependency                           |
-----------------------------------------------------------------
| Firebase Core   | com.google.firebase:firebase-core:17.0.0     |
-----------------------------------------------------------------
| Cloud Messaging | com.google.firebase:firebase-messaging:19.0.0|
-----------------------------------------------------------------
| Authentication  | com.google.firebase:firebase-auth:18.0.0     |
-----------------------------------------------------------------

此版本是主要版本的更新，其中包含重大更改。 在此版本中，库已从Android支持库迁移到Jetpack（AndroidX）库。 除非您在应用中进行以下更改，否则更新的库将无法工作：

将com.android.tools.build:gradle升级到v3.2.1或更高版本。
将compileSdkVersion升级到28或更高版本。
更新您的应用程序以使用Jetpack（AndroidX）；请按照Migrating to AndroidX中的说明进行操作。
