when i updated android studio i had this error :

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.

i've this error too but in gradle file ::::

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

You are using both support libraries and androidx libraries and you can't do it.

Check the official release notes of Firebase Libraries:

-----------------------------------------------------------------
|  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     |
-----------------------------------------------------------------

This release is a MAJOR version update and includes breaking changes. With this release, libraries are migrated from the Android Support Libraries to the Jetpack (AndroidX) Libraries. The updated libraries will not work unless you make the following changes in your app:

Upgrade com.android.tools.build:gradle to v3.2.1 or later.
Upgrade compileSdkVersion to 28 or later.
Update your app to use Jetpack (AndroidX); follow the instructions in Migrating to AndroidX.

i've migrated to androidx and i've this error : error:package android.support.v7 does not exist — zandroid arabapps, Jun 21 '19 at 17:13
@zandroidarabapps Check which is the class related to the error. This package (and this import) should be removed with only androidx library. — Gabriele Mariotti, Jun 21 '19 at 20:01
